Abstract
The historical site of Qalat Mutabad in Piranshahr is of paramount importance in numerous historical and cultural documents such as potteries and brick architectural remains, especially in terms of architectural maps and plans. The existence of a star-shaped plan in the design of the site’s outer fence illustrates the importance and pivotal role of this area in the Piranshahr plain. The site is located beside one of the branches of the Little Zab (or Lower Zab) River, which has been gradually destroyed due to the passage of time and the land-use change, “use as a military base in the contemporary period,” and currently the evidence of the architectural debris of the building at the site is evident. Examples of star-shaped plan design in different parts of Iran, as well as European fortresses, can be observed, and it is comparable to the plan of Qalat Mutabad in this respect. The main problem of this article is to evaluate the site relying on the available documents and evidence so that we study the importance of military forts in the Piranshahr plain while achieving a relative dating of the site. Accordingly, some questions about the architectural structure, especially its plan and the military and residential function of the site arise. According to written historical sources, the study of similar examples, as well as material artifacts at the site level, hypotheses concerning the attribution of the site to the period after Safavid, “Afshar or Qajar,” military function inspired by Western architectural elements, are presented. This study was conducted in a historical, descriptive-analytical method. In addition to studying historical sources and field documentation by the authors at the site, aerial images and data gained from these images were exploited.

Introduction
Qalat Mutabad site with an area of 20 hectares is located in Piranshahr city, 15 kilometers away from Tamrchin border crossing in south of Little Zab River. The plan of the site is star-shaped, overlooking the border crossings. In terms of architectural plan and location, Qalat Mutabad is noticeable and worthy of study.
Significance and Objectives of the Research: Concerning the destruction of the site and the ever-rising expansion of degradation factors, while introducing and recognizing Qalat Mutabad due to the lack of historical and archaeological data of the Islamic periods in Piranshahr, this study can contribute to the completeness of the information.
Questions and Objectives of the Research: Qalat Mutabad belongs to which period? What are the factors affecting the construction and star-shaped design of the site? It seems that this site belongs to the late centuries of Islam. Due to its geographical location and exposure to natural and political boundaries, Qalat Mutabad was built as a fortress and military base to repel the attacks of the Ottoman state or local insurgency.
Methods: The research method in this article is historical, and content analysis is descriptive-analytical. Aerial images explore written historical evidence and archaeological findings.
Literature Review: The historical site of Qalat Mutabad was pointed out in the photo book of Ali Khan Vali (Ali khan vali, 1862-1900: 183). In archaeological investigations, the Qalat Mutabad site with a history of 2500 BC, registration No. 611, was recorded in 1966 (West Azarbaijan Cultural Heritage Archives: 2019). The survey carried out in 2002 reviewed the site of Qalat Mutabad, and the area with historical-Islamic antiquity was registered as the hill of Qala-e-Mut with registration No. 7526 (West Azarbaijan Cultural Heritage Archives: 2019). In the study of Ali Binandeh for the master’s thesis “Archaeological Study of the Little Zab River,” he attributes this site to the Bronze Age, historical and Islamic period (Binandeh, 2008: 73).

Qalat Mutabad
Qalat Mutabad faces multiple problems, including the use of the site as a military base until recent years, industrial workshops in the area and boundary of the site, destruction by agricultural land, construction of garden houses, and the activities of unauthorized diggers. Problems have caused the site to lose its architectural structure and identity. For a detailed study, by utilizing satellite images of the Corona satellite taken in 1969, the site and its architectural structure are initially studied. Using the pictures of Ali Khan Vali’s book, a more accurate study of the site and its architectural evidence will be then addressed.
Below is the recorded photo, taken by Ali Khan Vali in the Qajar period, in which the word Qala-e-Mutabad was exploited. In addition to demonstrating that the site is a fortress, this historical document proves that the name of Mutabad has not been newly known in this area and has historical and old roots (Ali Khan Vali, Ibid: 183). The term Qalat in the Kurdish language means fortress, and it seems that Mutabad has come from the two words Mut + Abad. According to the evidence, before Iran’s Islamic revolution in 1978, there was a village called Motabad, which was evacuated after using the site as a military base in 1978 (Binandeh, Ibid: 73).
In Corona satellite images, the site has two parts of the outer fence with a star-shaped plan and the area’s inner part as a hill with a natural bed. There is a hill with a natural bed in the interior of the site. In unauthorized excavation cuts performed in the site, the thickness of ancient layers up to 2 meters is visible. Based on the Corona satellite images, an almost square-shaped area with suspicious architectural features can be seen at the top of the site.

Conclusion
Due to enjoying environmental potentials and also being located in the border strip of Iran with Mesopotamia, the Piranshahr region has always been a buffer zone due to successive wars from the Safavid period onwards with the formation of Safavid and Ottoman rules. With the coming to power of the Safavids and due to various gaps, local powers such as the Bilbas Tribal Union, the local governments of Savojbolagh Mokri and Urmia in Iran, as well as the local government of Baban in the Ottoman-ruled areas of Sulaimaniyah in Iraq, have turned the Piranshahr area into a scene of regional battles for various political, religious, and ethnic reasons. Historical documents and texts provide concise and beneficial information about the political and military situation in the Piranshahr area. Regional conflicts and wars mainly exhibit the military importance of the region and efforts to rule in it. About the existence of pottery findings and architectural works in the site of Qalat Mutabad and the lack of accurate dating of these findings because of their simplicity and locality, achieving a final decision based on the findings of pottery is impossible. Due to the existence of Corona satellite images and the intactness of the star-shaped plan of the Qalat Mutabad site and the presence of a photo of the site from the Qajar period and naming the site as the fortress, as well as the soundness of parts of the wall, towers, and architectural works in the photo, we can argue that not much time has elapsed since the destruction of the fortress. Accordingly, with comparative studies, the state of the landscape of the site and also the existence of similar examples of military fortresses with regular and star-shaped plans in the post-Safavid period “Afsharieh or Qajarieh” which are made inspired by European elements, the site of Qalat Mutabad can be attributed to Afsharieh or Qajar era.

Abstract
The Zab River basin contains the cities of Piranshahr and Sardasht in West Azerbaijan and parts of the city of Baneh in Kurdistan. The Zab River rises from the Northwest highlands of Piranshahr and after joining many branches passes through the highlands of Alan in Iran and enters Iraq. The extension of this basin is a relatively vertical strip along the Iran-Iraq border and the Little Zab River. Its orientation is Northwest to southeast and from west to east. The Zab Basin is located in an area with a cold and temperate mountainous climate, a Mediterranean rainfall regime, with average annual temperatures between 11.7°C and 13. 3°C and, 700 ml annual rainfall (Hojabri et al 95). This article tries to answer the question of how the cultural relations between this point and other areas of the presence of the late bronze culture have been established by studying the cultural materials belonging to the late bronze cultural tradition in Akhoran tepe. Also, what was the chronology of the stables? The results of archaeological excavations led to the identification of a late Bronze Age camp. The study of Akhoran cultural materials also indicates the presence of a late bronze pottery tradition. Studies and relative chronology of pottery showed that most of the cultural interactions and influences were with Hasanlu regions and outside the borders of Iran with Anatolia and Iraqi Kurdistan. The present study is based on archaeological excavations and then library studies and with a descriptive-analytical approach tries to introduce new pottery of the late Bronze Age.

Introduction
The Bronze Age is considered to be the beginning of major social changes in the early third millennium BC. The Hasanlu VI period or the Middle Bronze Age covers from 2100 to 1700 BC (Danti 2013:332 .Table 17.1). During this period, multi-colored and painted wares were commonly used in large parts of Azerbaijan (Dyson 1969). Hasanlu VI ceramic designs were in crossed, checkered, and triangle forms (Dyson 1965). The simple painted pottery, which is the characteristic of the Middle of the 2nd millennium BC, is the same as synchronously identified dishes of Khabur from Northern Mesopotamia and South West Turkey (Dyson 1969: 43-44). Our information on late bronze age in northwest Iran is quite limited. Hasanlu V, is of great importance in this region, but the period has been given relatively little attention. We therefore selected Akhoran Tepe for excavation with the goal of closing this chronological gap in our understanding of Iranian prehistory.
As a local center, the Zab basin generally witnessed the alternation of contacts and conflicts, as is evidenced by the varying patterns in the distribution of recorded sites. Unlike what is characteristic of Mesopotamia and southern Iran in the fourth millennium BC, it has not yet produced any traces of extended settlements and social complexities. 
Previous studies have illustrated that northwest Iran maintained contacts with regions south of Caucasia and the valleys hemmed in by the Aras and Kura rivers to the north, the Central Zagros to the south, and eastern Anatolia and north Mesopotamia to the west via mountain passes. 
Recent archaeological data from the adjacent neighboring regions has corroborated this observation. Therefore, serious investigation in the region has the potential to shed light on broad cultural interactions and evolutions in the middle and northern Middle East. 
The data from Akhoran is thus of considerable importance in this respect, and can improve our understanding of regional and inter-regional interactions. A foremost purpose of this paper is to look into the ties and connections between Akhoran and northwest Iran as a whole, and to explore intra- and inter-regional interactions.
One of our fundamental problems in North West Iran was the lack of excavations, with little information about the Archaeology of the region. The current paper focuses on Akhoran Tepe since we have had a little knowledge about the late Bronze Age in the Little Zab River. 

Archaeological Background
North West Iran has a particular Archeological importance since it accumulates different prehistoric periods. The area is also important from the point of view of Archeological literature since it is at a crossroad facilitating the passing of nations and trading. With regard to the history, the basin is among those that attracted the attention of domestic and foreign scholars at the dawn of professional Archaeology in Iran (Motarjem Sharifi 2014: 50).
A long-lasting Hasanlu Project started by the Museum of the University of Pennsylvania in 1956 under the guidance of Robert H. Dyson, is the most significant work carried out in this basin (Dyson, 1968; 1969). On the other hand, the work at Yanik Tepe, the Northeastern basin of the lake began in 1960 by Charles Burney that furnished important details, among them the identification of the Trans-Caucasian culture’s infiltration into Northwestern Iran (Burney 1961; 1962; 1964). Indeed, earlier excavations conducted by Burton-Brown at Geoy Tepe, in the same basin, had uncovered evidence of the Trans-Caucasian culture at Level K (Burton Brown 1951). Later excavations by Burney at Haftvan Tepe brought to light further aspects of the Bronze and Iron Age cultures.
This region experienced the Middle Bronze culture known as Urmia ware with monochrome and polychrome pottery. Danti divides the Middle Bronze Age into three periods (Danti 2013: 332).
We also know about the Urmia ware in Haftavan VIB. Investigation and recognition of the Urmia ware was carried out by Edwards (Edwards 1983).

Conclusion
Akhoran can well supplement the limited dataset at hand for Hasanlu V. An important point about this site is the absence of the middle bronze material culture. Tepe Akhoran is one of the sites with deposits of the Late bronze age within the prospective reservoir of the kani sib  Dam. The main objective of this excavations is to establish the cultural sequence of the site. Other aims include dating the most important settlement attested at the site, and pinpointing the subsistence system of the late bronze age community that occupied it. The nature of the settlement and material culture of the Hasanlu VI period in Dinkhah Tepe and the limitation of the Khabur pottery to the southern areas of Lake Urmia strongly suggest that during this period, people from Mesopotamia migrated to the Ušnu- Solduz valley (Danti et al 2004.584).  In the Piranshahr area, excavations at Akhoran Hill provided evidence of a new bronze tradition in the Zab Basin.
The most important cultural material of the Akhorn  in  late  bronze age is  potteries, which is produced in a simple and painted sherds. The pottery from Tepe Akhoran is comparable to the material coming from the, Azerbaijan and the Anatoly. 
The pottery is decorated with geometric patterns. The shape of the dishes is more inclined to closed-mouth dishes. Also, what the data of Akhoran excavations show indicates the cultural relations of this region with other parts of the Urmia Lake basin, including Hasanlu, and outside the borders of Iran, the areas of Anatolia and Iraqi Kurdistan. This area may be geographically more inclined to Anatolia. 

Abstract
In explaining Iron Age archeology, the study of metal artifacts is of particular importance because of the hidden technical values. The study of metalworking methods enhances our understanding of the industrial centers of metallurgy, stylistics, and available mines. The purpose of this study is to identify the methods of construction and elemental analysis of “ornaments” discovered from “Iron Age” sites in northwestern Iran, using metallographic experiments and an SEM-EDS elemental analysis device. In the Iron Age, the making of metal objects, especially those with many ornaments, flourished. Therefore, knowing the manufacturing methods and the type of alloy used in them is one of the essentials of this research. This research responds to the question, what methods used to make the discovered ornaments from the Iron Age sites in the northwest? Or what were the most used elements in the construction of these objects? In these areas, the current research hypothesis is that most of the “ornaments” made by hot hammering and casting methods and have a large amount of tin in their structure, which uses for greater strength and flexibility of copper and tin (bronze) alloys. In this study, several samples of ornaments discovered from Iron Age sites in northwestern Iran, which were geographically very close to each other, were tested by metallography and elemental analysis. In this experiment, using a scanning electron microscope equipped with an SEM-EDS element analyzer, making these metal objects and their constituent elements were determined. This study shows that the main methods of making these metal objects have been hot hammering, but those objects that had a large volume made using the casting method. Also, the most used element to increase the strength and flexibility of objects is the element of tin.

Introduction
In the Iron Age areas of the northwest, metalworking was done at an advanced level. The expansion of the tradition of metalworking in the northwest can be seen in other Iron Age areas of Iran. (Talaei, 2001:77-83) One of the reasons for the development of metalworking in the Iron Age areas of northwestern Iran has been the abundance of copper and iron ore mines in this region. During the excavations of the Hasanlu area in the south of Lake Urmia, founded a large number of iron and bronze objects. The large volume of metal objects discovered in the Hasanlu area indicates the prevalence of metalwork in this region of the Iranian plateau. (Pigott, 1989: 67-79) According to the studies, the residents of Hasanlu have supplied their required copper ore and iron ore from the mines that probably existed around this area. The development of metalworking art in this region, in addition to the existence of metal mines and fuel reserves, has been the development of furnaces and metal smelting molds, which in some Iron Age sites such as Hasanlu, obtained a large number of these metal smelting molds. The main reasons for the development of technology and style of metal products in northwestern Iran in the Iron Age could have been powerful governments such as Urartians and Manas. (Aliun and Sadraei, 2011) They were skilled metalworkers in the vicinity of Iron Age sites. One of the signs of this effect is discovering a bronze bracelet discovered in the Toul Talesh cemetery in northern Iran, which shows the expansion of Urartian territory in this region. There is a Urartian cuneiform inscription on it. This inscription shows that Argishti II, King of Urartu, gave this bracelet to Khaledi God. This person could have been a prince or a military person. (Tahmasebi and Masoudi Nia, 2015) The main issue of this research is to know the construction methods and the constituent elements of the jewelry discovered from the northwestern region of Iran. In the Iron Age, especially the Seldouz valley, these sites are primarily located in the Seldoz Valley and are geographically very close to each other, which can help understand the methods of construction and elemental analysis of the metal samples tested. The present research has been done by analytical-experimental method and based on scientific and laboratory studies. The purpose of this study is to identify the methods of construction and elemental analysis of “ornaments” discovered from “Iron Age” sites in northwestern Iran, using metallographic experiments and an SEM-EDS elemental analysis device. This research responds to the question, what methods used to make the discovered ornaments from the Iron Age sites in the northwest? Or what were the most used elements in the construction of these objects? In these areas, the current research hypothesis is that most of the “ornaments” made by hot hammering and casting methods and have a large amount of tin in their structure, which uses for greater strength and flexibility of copper and tin (bronze) alloys.

Materials and Methods 
In this research, the first eight metal samples from different Iron Age sites in northwestern Iran were collected through the reservoir of the National Museum of Tehran and sampled in the same place, and then sent to the Materials and Metallurgy Laboratory of the Sharif University of Technology for metallographic testing.

Discussion
Laboratory analysis and elemental analysis of metal samples using the SEM-EDS method show that a small amount of arsenic was founded in the alloy composition of the samples Because most copper metal ores before extraction and smelting contain amounts of arsenic. Therefore, there is a possibility of the unintentional existence of arsenic in the composition of these metals. Another element that a large percentage obtained in the composition of these metal samples is tin. Metallographic images of the ML-98-7 and ML-98-8 specimens show that these two specimens have a branched or dendritic structure in their body and are made by casting. Also, tiny cracks on the metallographic images of ML-98-2-ML-98-3 and ML-98-6 samples formed due to stress and fatigue caused by continuous hammering work on these metal works. The dark spots seen in most of these microscopic images indicate oxygen, carbon, and a lack of copper and tin, which have caused corrosion and sulfidation of these metal objects.

Conclusion
The results from the images obtained by scanning electron microscopy equipped with an SEM-EDS device found that the metal samples have a relatively large amount of tin. A small percentage of arsenic found in the metal samples tested. Considering the amount of arsenic in these samples can be concluded that metalworkers of this period may not have noticed the harms of using arsenic at that time and therefore used this element to improve the properties of bronze alloy. Ancient metalworkers used tin, arsenic, and antimony elements in the composition of bronze alloys to increase the hardness of the work. The items in the category of jewelry need to pay more to get the right shape. Another possibility is the unintentional presence of arsenic. The presence of large amounts of tin in these samples indicates that arsenic may have been naturally present in copper ores and Ancient metalworkers used tin to lower the melting point of copper and increase its strength and flexibility. Microscopic studies of bronze objects show that many copper sulfide compounds are present in metal samples. The presence of copper sulfide inclusions dispersed on the surface of the metal matrix and stretched in the longitudinal direction of the microstructure of ancient copper alloys may indicate the use of oxide ores along with some copper sulfide ores for extraction. Most of the ornaments found in the northwestern Iron Age sites, such as bracelets and collars, were made by hot hammering, subsequent hammering or forging, and objects with larger volumes and decorations molded by casting. In general, the objects discovered from the Iron Age sites in the northwest, especially the Hassanlou site, are more complex in terms of technique and construction style than the Iron Age sites in other parts of Iran, where existed local and indigenous governments. This issue has been due to the proximity of northwestern Iran to powerful governments such as Urartu and Manna.

Abstract
Bampur historical complex is located in Makran – Jazmourian Basin in a flat plain in the Northwest of Bampur city, the capital of the region and 4 km to the North of Bampur River (20 km to the east of Iranshar). Extensive firing and burnt vestiges are one of the most characteristics phenomena at Bampur Castel. The evidence of firing is scattered nearly all over the site and it is not limited just to spaces like pits or kitchens. The diversity and abundance of brunt materials (seed of cereals, fruit remains, woods, charcoals and mat-made shoes) allowed us to use them for archaeobotanical studies. Due to the limited archaeological excavations especially in prehistoric sites, Iranian Baluchestān has so far been less-known from archaeobotanical and history of vegetation point of view. This research present the results of studies on the plant remains obtained from some pits and firing debris belonged to the Qajar period’s layers. The purpose of the study was to recognize the vegetation around the site and the type of plants used by the inhabitants during that period. Microscopic observations and analyze of 2301 charcoal fragments, woods, seeds, rachis segments and fruit remains showed that the vegetation cover around the Castel included trees such as tamaris, willow, acacia, musquit bean and date palm. They used the wood of these trees to meet their fuel needs (especially tamaris) or as construction materials (willow, acacaia and mesquites). Given the current ecology and geographical distribution of these species, it is reasonable to assume that the identified trees are native to the area and have grown around the Castel. Also the remains of Cereals (wheat and barley), fruits (date palm) and Cucurbits (Watermelon and melon) found in the firing debris testify agricultural activities. In addition, further evidence is attested by the presence of burnt seeds of the wild plants or weedy such as rye, bermuda grass, brome, wild grass, vetch milk, vetch, medic, goosefoot family, knotweed, seepweed, cowherb, asphodel and sedge family (present in the fields along with agricultural products).

Introduction
The study of vegetal remains is not solely limited to climate change that occurs normaly over a long period of time. It could be used for reconstruction of vegetal cover, cultivation patterns or the introduction of non – native species compatible with the environment of a specific region. 
Bampur castel is located, in a flat plain on the northwest side of Bampur city, 4 km north of Bampur River and 20 km east of Iranshahr. The castel have a rectangular – oval shape in the northeast- southwest axis. Due to the best state of conservation at the site, large quantity of vegetal remains including seeds, fruit remains, woods, charcoals and reed mat and other artefcats were found in archaeological contexts. 
The present research will study plant data obtained from the excavated layers in the second season of excavations at Bampur castel conducted by Nozar Heydari in 2018 (heydari 2018). Here, we will try to answer to the following questions: 1. What was the vegetal cover around Bampur in the late Islamic period (Qajar period)? 2. Which kind of woods were used by the inhabitants of the region during that period? 3. What plants species were cultivated by the inhabitants as food resources?
Unfortunately archaeobotanical studies have not been realized in Iranian Baluchestān. Henece, for the first time archaeobotanical studies have been applied to identify the vegetation history of the area, the plant resources and the possible existence of non – native species. The Information on the agriculture and plant economy of Pakistani Baluchestān during the prehistoric times has been available (Tengberg, 1998; 1999; Tengberg & Thiebault, 2003; Costantini, 1981; 1990). However in the Iranian Baluchestān, no specialized study has been conducted in this field. In the southeasten part of the Iranian Plateau and in the Indo-Iranian Borderlands (Sistan, Baluchestān and Kerman) several long-term environmental studies have been carried out in some prehistoric sites by iranian and foreign experts resulted in obtaining valuable information on the history of agriculture and vegetal cover of the area (Costantini & Costantini-Biasini, 1985; Costantini, 1977a-b;  Costantini, 1979; Meadow, 1986; Shirazi & Shirazi, 2012; Tengberg, 2008; Mashkour et al., 2013 ; Vaezi et al., 2019; Hamzeh et al., 2016; Gurjazkaite et al., 2018; Shirazi 2019; Kavosh et al., 2020).

Material and Method
In the second season of excavations a total of six trenches were excavated including:  W1.T2, W1.T3, W1.T4, W1.T5, W1.T6, W1.T7. The archaeobotanical data were obtained from W1.T2, W1.T3, W1.T4, W1.T5. Extensive traces of fire and ashe were scattered all around the castel. Considering the diversity and large quantities of plant remains (grains, fruitstones, charcoals, woods and artefacts) it was decided to select them for archaeobotanical studies. In total, 10 samples from contexts such as pits and fire debris have been collected. From 153 litres of collected debris by water sieving, about 5690 ml. plant remains including seeds, fruitstones and rachis segments were obtainted. Laboratory studies of these data have been done in the Archaeobotanical Laboratory of the World Heritage Site of Shahr-i Sokhta.

Discussion
A total of 310 fragments of charcoal and woods and 1991 seeds, fruit stones and rachis segments were studies. Anthracological digramme indicates the presence of various trees and shrubs such as tamaris (Tamarix spp.), willow (Salix sp.), date palm (Phoenix dactylifera), acacia (Acacia sp.) and mesquites (Prosopis sp.). The relative abundance of tamaris and willow is higher (79%) than other plants. Tropical plants such as acacia and mesquites (15%) and fruits like date palm (6%) are in the second and third ranks respectively. This evidence shows that the inhabitants used the wood of tamaris as fule and willow, acacia and mesquites as construction materials. Given the habitat and geopraphical distribution of the actual vegetation, it is quite reasonable to assume that the identified trees are native to the area.
In addition to the identified trees, carpological digramme indicates the existence of various crops like cultivated cereals  (emmer wheat/Triticum dicoccum), bread wheat /T. aestivum, club wheat /T. compacteum and barley/Hordeum vulgare), fruits and cucurbits (date palm, melon and watermelon), wild grasses (rye, bermuda grass, brome), wild pulses (vetch milk, vetch, medic), and wild plant or weedy (goosefoot family, knotweed, seepweed, cowherb, asphodel and sedge family) that were present in the fields along with agricultural products.

Conclusion
According to our study, plant resources around Bampur includs trees such as tamaris, willow, acacia, date palm and mesquites. Tamaris is the main source of fuel in the region and willow, acacia and mesquites have been used as construction materials (beams for building strengthen). The remains of charcoal and wood of these trees in the explored contexts show that the inhabitants of the castel did not need to import wood from other areas to meet their needs and were completely self-sufficient in this regard. In addition to these tree, which grew naturally in the past as they do today, Baluchestān also enjoyed favorable conditions for cultivation of cereals (emmer wheat, bread wheat, club wheat and barley), cucurbits (melon and water melon) and other fruits especially date palm. 

Abstract
Northwestern Iran and the South Caucasus have relatively favorable environmental conditions for the formation of ancient settlements. These include the Urmia Lake basin and the Aras shores in northwestern Iran, and the Kura River, the Mil-Moghan (mountainous areas) in the South Caucasus region. The archaeological evidences and recent researches in two geographical areas illustrate the cultural shares and similarities of the period. The main purpose of this article is to introduce the areas and pottery traditions and to identify the sequence of chronology in the areas of study. The following questions will be raised in order to achieve cultural interactions in the geographical area studied in the Chalcolithic Period: How is the condition of chronology sequence in the two cultural domains? The main hypothesis in this regard is the existence of approximately the same chronology (the beginning and the end of the Chalcolithicperiod) in the two geographical locations. How do the layers of settlement and the sequences of residence from the Neolithic to the Chalcolithic Periodin ancient sites indicate the theme of cultural continuity and transition? The present article is written by descriptive-analytical method. As a final result, it can be pointed to the similarities and differences of the archaeological data, including thepottery features, architectural structures, burials, etc. By studying the areas such as Dalma Tepe, Jolfa’s Kul Tepe, Khoy’s Davagöz, etc. in northwest of Iran and Leila Tepe, Galayeri, Puylu Tepe, Boyuk Kəsik, Soyuq Bulagh, Brikil Dibi, Kawtskhevy, Tekhvot have been obtained in the South Caucasus region and chronologically covers the millennium from 5000 BC to 3700/3600 BC. 
Keywords: Chalcolithic, Northwestern Iran, South Caucasus, Cultural Interactions, Chronology.

Introduction
The northwest of Iran and the Caucasus have long been a prominent site for archaeological studies due to their proximity to important cultural sites such as Anatolia, Zagros, Mesopotamia and Central Asia. Most of the ancient sites both in the Caucasus region and in the northwestern Iran, which were inhabited by the Chalcolithic period, were also inhabited during the Neolithic period, suggesting that the human and animal habitat conditions and the environmental conditions are favorable. The following questions will be raised in order to achieve the cultural interactions in the geographical area under study in the Chalcolithic Period: 1. What is the status of the chronologysequence in the two cultural areas? The main hypothesis in this regard is the existence of a same chronology (beginning and end of the Chalcolithic Period) at two geographical points. 2. How do the layers of settlement and settlement sequences from the Neolithic to the Chalcolithic Periodsindicate ancient sites, cultural status, and the cultural continuity and transition themes? Most of the ancient sites both in the Caucasus region and in the northwestern Iran, which were inhabited by the Copper-Stone period, were also inhabited during the Neolithic period, indicating the existence of afavorablehabitat and environmental conditions for both human and animal. Although there are also single-period enclosures among them.

Discussion
In recent years, one of the most significant issues in introducing and studying the Chalcolithic culture of northwestern Iran havebeen the ambiguity and darkness in the timing chronology of the Chalcolithic Period of this region. Because, this period was introduced after the late Neolithic period, was identified in areas such as Haji Firouz, Hassanlu, Yaniq Tepe, etc., with a break of almost a thousand years. Dr Abedi’s recent years’ excavations atJolfa’s Kul Tepe and Khoy’sDəvə Göz have eliminated the gap in the timing of the Chalcolithic Period of northwestern Iran (Azarbaijan). The archaeological studies are divided in twostages; and its early stage dates back to the 19th century and is known as the Eneolit cultural period. The archaeologists in the North Caucasus geographical area of have identified two culturaltypes of Kura-Arax and Maikop in the Chalcolithic Period, hence, the two Kura and Araxrivers in the Caucasus Basin are named as the Mesopotamia of Caucasus.
One of the most important cultural data of the Chalcolithic Period is the rectangular architectural structures which are made of white raw clay. Inside the structure, large crumbs, food storage wells and numerous stoves, along with the data such as mortar, and grindstone, and burned remnants of grains such as barley, wheat and lentils have been obtained. The burial variety ofthe Chalcolithic Period is more diverse than the Neolithic period. The most repeated type of burial in the Chalcolithic Period is the pits burial, but more recently therehave also been found two other burial types such as burial in earthenware, and kurganburial.

Conclusion
One of the most important issues of Chalcolithic culture in the South Caucasus is anunbroken continuation of the Chalcolithic Period after the Neolithic period. This continuation can be seen in Mentesh Tepe, Aratashen, Khatun Ark- Aknashen, and theChalcolithic Period begins unbroken after the Neolithic periodin these areas. But after the Neolithic period, the Old Bronze Age beginsinNakhchivan’s Kul Tepe. Scientists consider the climate change as the main cause of cultural disruption. In the southern Caucasus, the earlyChalcolithic phasehas been dated from 4800/5000 to 4600 BC, and themiddle andthe lateChalcolithic phases from 4600 to 3200 BC, and some new areas, such as Nakhchivan Tepe, Uchan Aghil, Uzun Oba, is derived from the earlyChalcolithic Period that are closely related to Dalma culture.

Sarakhs plain is located in northeastern Iran and adjacent to Turkmenistan. Regarding Parthian pottery studies in Sarakhs plain, no special components have been considered for it so far. Identification and classification of Parthian pottery in this region can be a good tool to better understand the pottery traditions, study the cultural and economic interactions of the population centers of that period. The research method is based on library and field studies (descriptive and analytical) during a field survey (survey) stage. Based on the surface findings of the field survey, a total of 91 flagship pottery pieces from 14 settlements belonging to the Parthian period were selected for the survey. In fact, this study seeks to answer the question of what were the intra-regional and extra-regional relations of Sarakhs plain during the Parthian period with contemporaries? According to the studies on pottery attributed to the Parthian period in Sarakhs plain, this period can be divided into two periods in the mentioned plain. In the first period (formation of Parthian rule before the reign of Mehrdad I) Sarakhs is influenced by the culture of the Sarakhs oasis of Turkmenistan, and in the second period, until the end of the Parthian period, they are influenced by the well-known cultures of southern Turkmenistan, namely the cultures of Nessa and Merv. The purpose of this study is to identify and introduce Parthian pottery in Sarakhs plain, classification and typology of Parthian pottery in the region. The necessity of the present study is that the pottery cultures of the Parthian settlement of Sarakhs plain are unknown and the present study can provide a better understanding for further research.

Introduction
Sarakhs plain as a study point due to its natural potentials and optimal environmental conditions such as altitudes, suitable soil and relatively favorable weather conditions, has been a desirable habitat for the formation of various human communities (Ebrahimi, 1384: 2). Scholars in historical texts have stated the origin of the Parthians in northeastern Iran, especially Khorasan (Asak near present-day Quchan) and their primary capital was Nessa in Turkmenistan (Altheim, 2010: 20). Based on the field surface findings, a total of 91 flagship pottery pieces from 14 settlements belonging to the Parthian period were examined. The method of this research is based on library and field studies (descriptive and analytical) during a field survey (survey) chapter. Documentation of human handicrafts is necessary in terms of studying the background and type of community culture at any point in history.      
Research Questions and Hypotheses: In fact, this study seeks to answer the question of what were the intra-regional and extra regional relations of Sarakhs plain during the Parthian period with contemporaneous areas? Therefore, in the present study, surface cultural materials have been interpreted by preparing a statistically citation able and scientific population through archeological study. Analyzes obtained from classification, typology and methodological analysis of this statistical population as well as comparative comparison of pottery species with similar examples of contemporaneous settlements show the formation of sequences of some settlements in the Parthian period and continuous continuity before and after the Parthian period in this Has an area.                                                                                                    
Aims of Research: The purpose of this study is to identify and introduce Parthian pottery in Sarakhs plain, classification and typology of Parthian pottery in the region.                                                       

Materials and Methods
The present research is based on the purpose of basic research and based on the nature and method of descriptive-analytical research. The basis of the research is the study of Parthian pottery along with library studies. Methods and tools of data collection in this research have been done in two ways: documentation and field activities. In the documentary stage, all written sources, images and maps were first collected and analyzed. In field studies, while surveying the plains in the region and identifying the settlements, the required archaeological information and evidence (pottery) were collected from the mentioned areas and recorded in the database. In order to compare the chronology of the settlements and analyze the pottery of the Parthian settlements, the total pottery collected from 14 Parthian sites was examined and compared with other sites of the Parthian period such as Nessa, Merv and Sarakhs oasis of Turkmenistan. It was not possible to identify more Parthian sites through surface surveys. 91 index pottery were selected for photography, design, classification, typology and comparison with other Parthian sites. The index samples were selected as research materials based on classification and typology. In archeology, when classifying, the differences and similarities of the pottery in question must be clearly evident in the various groups that are distinguished; In such a way that no further explanation is needed for easy identification of one group from another. It is logical to expect that no two groups of objects classified in the main and important criteria are common to each other (Azarnoosh 1377: 76). In the present study, first, in a general division, pottery pieces are divided into five general categories, including: 1- edge 2- body 3- floor 4- base 5- handle, and then edge pieces that can be recognized in the form of a container. 

Discussion and Results  
In this study, 91 Parthian pottery pieces were identified from 14 ancient settlements related to the Parthian period, many of which have chronological sequences and in addition to the works of the Parthian period, also have the works of other periods. Settlements were classified based on pottery typology, comparative studies of pottery find, and archaeological excavations in southern Turkmenistan, northeastern Iran, eastern Iran, Pakistan, Afghanistan, and other regions within and outside the region. A total of 26 sites in 11 areas for this study in the order in which it is presented has the most references. Based on this, a table was designed for each cultural region and settlements of each basin in which the amount and percentage of comparison is clearly significant (Table 2).     

Conclusion
Archaeological study of Sarakhs plain and 91 surface pottery pieces from 14 Parthian settlements were considered as the main foundation for relative chronology, classification and typology of the research. In order to obtain a scientific answer to show the cultural interactions, the method of comparative analysis was used and the findings of the archaeological study of Sarakhs plain were compared with the findings of intra-regional and extra-regional contemporaneous areas. These similarities, taxonomy, morphology, typology, and cultural connections were evident and analyzed. What results from the study of Parthian pottery findings obtained from the Sarakhs plain; According to the studies carried out on pottery attributed to the Parthian period in Sarakhs plain, this period can be divided into two periods in the mentioned plain, in the first period (formation of the Parthian government before The accession of Mehrdad I) to the Sarakhs plain is influenced by the Sarakhs oasis culture of Turkmenistan, and in the second period, until the end of the Parthian period, they are influenced by the well-known cultures of southern Turkmenistan, namely the cultures of Nessa and Merv. The presence of these pottery indicates a two-way and dynamic relationship.    

Abstract
The northeast Iran has been the context of some of the most important events of the Parthian Period, in a way that one can restrict the geography of the Parthians to Pathawa and Hyrcania until before gradual expansion of the territory during Mehrdad the First (138-171 BC).One of the least-known aspects of the Parthian in the northeast region is the potteries assemblages. Pottery is the most abundant of the archaeological finds and is the most important one to understand the cultural specifics of the historical periods. The Parthian pottery is not the same throughout the whole empire and it can be grouped into several categories based on geographic regions. The pottery assemblage under study in this paper, collected from two seasons of excavations at ShahrTappeh in Dargaz, represents part of the Parthian pottery corpus of the northeast region. In current research, the pottery aasemblage of ShahrTappeh has been studied from the typological perspective and it has been tried to put forward specifics of the pottery of Parthian period of the northeast region by comparative studies of the similar assemblages.The most frequent forms amongst the pottery assemblage of ShahrTappeh are jar, pithos, handled jar, pot, caldron, trough, bowl and cup. These forms, which are seen from the early to late phase of the Parthian period, are comparable with specimens from Marv, Nisa, Qumes, Chasada, Shamshir Ghar, Ai Khanom, HasaniMahale, Tol Espid, Tappeh Yahya, Bardsir cemetery, Gowri Kohneh, Nadali, south of Baluchestan, Khorheh, Sang-e Shir cemetery, QalehEzhdahak and Bisotun. In addition, finding of some kiln waste in the second season of excavation at ShahrTappeh suggest that this site was a center for pottery production in the northeast during the Parthian period. Lack of glazed ware, rarity of the painted ware and the prevalence of the plain ware are the most characteristics of the ShahrTappeh pottery assemblage. The latter was used as common ordinary ware during the Parthian period and based on comparative studies they were parts of the pottery tradition of the Parthians.

Introduction
The site of ShahrTappeh is located near the town of Chapeshlow in the northeast Iran. From several aspects this site has important in archaeology of the Parthian Period: with more than 70 ha, the site of ShahrTappeh is one of the largest sites of this period in the northeast Iran; 2. The site is just 100 km, as crow flies, from the first capital of the Parthians; 3. Archaeological data, including fortifications, acropolis, sharestan (lower town), industrial quarter and cultural materials recovered from the excavations comparable with those from Nisa, suggest that the site was a city in the Parthian period; 4. Based on materials recovered from the surface and excavations, ShahrTappeh was a single-period site of the Parthian period in the northeast region. These items suggest that ShahrTappeh was one of the most important Parthian centers of the northeast region. Regarding the importance of the site of ShahrTappeh in the northeast region we try in this paper to discuss the main pottery characteristics of the site to some extent. In this line, first we have studied the pottery forms of the site and then we have chosen 89 sherd fragments and whole vessels for in-depth studies. We have tried to choose the pottery sample so that it is the representative of the whole assemblage. In the following the pottery assemblage has been divided into two classes: open forms and closed forms, and then each class has been discussed. Finally, we tried to discuss, in a separate part, the common features of the Parthian pottery of the region from this study and at the end we propose a pattern for identification and characterization of the Parthian pottery in the northeast region. 

Typology and General Characteristics of the Study Sample
From the pottery collection recovered from two seasons of excavations at ShahrTappeh, 89 pottery fragments and whole vessels were chosen for study here. At the first stage, these potteries are divided into two classes: open forms and closed forms. The closed forms of the ShahrTappeh assemblage include necked jars and simple jars, pithoi, stoups, caldrons, troughs, a vessel type known as Misagh and base fragments of the vessels. The open forms include bowls and cups. Without considering the various types of forms, the ware has some general characteristics. The pottery collection under study is all plain. No glazed ware is found in ShahrTappeh yet. Some of the sherds have incised, applique or burnished decorations. The sherds usually have mean thickness, but both thick and thin variants are also seen. The color paste covers a spectrum: buff, light orange, orange, red and gray. The color of slip ranges from buff, light buff, dark buff, greenish buff, orange buff, reddish buff, buff orange, light orange, dark orange, reddish orange, red, greenish red, buff brown, gray to greenish gray. All samples are wheel made and the temper agent used is mineral, including sand, silt and white particles. The kiln temperature was enough and all sherds were exposed to proper heat. 

Conclusion
With more than 70 ha in area, ShahrTappeh is one the largest Parthian sites of the northeast region. The important point about this site is that it is a single-period site and discussing about its finds can be pursued from this perspective. One of the most important finds of ShahrTappeh is pottery. Except typological and technical grounds, the Parthian potteries of ShahrTappeh can be assessed from the viewpoints of chronology, comparable specimens, imported potteries and local production. The potteries assemblage of ShahrTappeh is datable to the early to late Parthian period. This conclusion is based on comparative grounds. On this basis, the ShahrTappeh specimens are comparable with those of eastern Parthian Empire. The early Parthian potteries of the site are comparable with those of Nisa, Marv and Qumes. Some of the specimens are comparable with pottery from Charseda, Shamshir Ghar and Ai Khanomwhich are categorized in the Seleucid-Parthian context. Although the site established in the early Parthian period, it lasted to the end of the era. Among the potteries assemblage of ShahrTappeh there are specimens that are comparable with those from Tol Spid, Tappeh Yahya, Bardsir cemetery, Gowri Kohneh, Nadali, south of Baluchestan, Khorheh, Sang-e Shir cemetery, QalehEzhdahak and Bisotun. The pottery types of ShahrTappeh can be assessed from the import and local production viewpoints. Amongst the potteries of ShahrTappeh a burnished vessel dated to the 1st to 3rd centuries AD has been found. Existence of this specimen indicates the importation of such vessels from the southeast region to the northeast region including ShahrTappeh. On the other hand, discovery of large amounts of kiln waste suggest that the site was a manufacturing center for pottery vessels. It should be noted that as no deformed specimens were found, we cannot make comments about the local variants. In general, potteries of ShahrTappeh which are comparable with assemblages from the eastern Iran can be dated from the early to the late Parthian period. These pottery types that in which imported specimens and local production can be seen, are representatives of some of the Parthian pottery types of the northeast region. 

Abstract
The Iranian house is full of structural units. The cohesion of the units creates more complex patterns, which, as a result of their location in different parts of the building, also form its physical structure and functional and cultural characteristics. Since the combination of these patterns in the home is always a reflection of the customs and lifestyle of residents and local conditions, knowing each of the patterns allows them to be used on a larger scale in the design of new homes. The content of structural patterns and the extent of their impact on Iranian-Islamic residential architecture is the basis of research inquiry. The research intends to take a physical approach to express the structure of the architectural language of the house in the sample buildings of the Qajar period; and in this way provide the basis for restoring the architectural values of the past. The research method is descriptive-historical and the method of finding research is a combination. The basis of observational studies has also been done through the presence of buildings that have a relatively complete architectural composition, and citation of existing maps, images and texts. The abstracted contents with the help of AutoCAD software introduce the basic units in geometric shapes and check their applicability in 50 houses of historical-cultural value. One of the important results of this search is the generalizability of the logical order of the initial units identified in various combinations and the production of more complex spatial units than the initial units of 5040 patterns. The results show that the patterns participate in various proportions from 0.06% to 27.16% and 42 in selected houses. Among these, pattern number 8 has the most (453) presence; while Patterns 12, 33 and 42 have the least (1) applications.

Introduction
Due to the common economic and social prosperity, the residential houses of the Qajar period define a rich language in architecture that can be extended to Iranian-Islamic houses in the contemporary and future periods. Field studies show that there are a variety of patterns in residential homes that are physically part of a sequential structure and order. From the coherence of these initial units, more complex patterns emerge, which, according to their location in different parts of the building, express the physical structure and functional and cultural characteristics of the building. Since the combination of these patterns in the home is always a reflection of the customs and lifestyle of residents and local conditions, knowing each of the patterns allows them to be used in the design of new homes on a larger scale.
Housing construction in the contemporary era of Iranian architecture and urban planning, especially in recent decades, has found significant differences with the previous era. Field studies and observations indicate a significant reduction in physical-cultural values arising from new housing methods. For example, the gradual obsolescence of the middle fabric of cities is an issue that easily causes their instability. 
This study tries to identify the past methods in housing architecture and highlight the points of emphasis in its structures and concepts, and then shaping those features into a new format, introduce the most important effective spatial patterns in order to improve the physical and quantitative structure of modern house.
According to historical background of home architecture in Iran, and the need to review the structure of modern home architecture, research seeks to find answers to these questions: 1- What are the basic spatial units in the architecture of the Iranian-Islamic house? 2. What patterns does the spatial order of the units create? 3- What is the frequency of these patterns in the existing samples?

Survey of Basic Spatial Units
The research has summarized the data using a descriptive-historical method. A review of studies conducted by researchers and experts in Iranian and non-Iranian architecture and urban planning confirms the similar and sometimes different points of view of the linguistic structure of Iranian-Islamic architecture. Each of the statements has somehow emphasized the characteristics of Iranian-Islamic architecture; and they are summarized at the crossroads of the world of meaning and the world of matter and are located in six directions (Falamaki, 2012, 194).
In the Iranian- Islamic culture, it is believed that matter or the material world is opposite to light or the spiritual world (Holy Quran, Esra: 70). In Iranian-Islamic architecture, the spatial arrangement of the body shows that, in its spatial organization, attention is directed from light to matter. In fact, “it is a journey from pure light to the depths of matter” (Holy Quran). Although architecture is shaped by the combination of matter and space, form is created by the domination of space. Therefore, the form depends on the arrangement of the initial units that make up the architecture of the building. These units include a closet, room, living room, hall, porch, Platform, courtyard and basement.
Examination of the frequency of practical application of patterns in sample houses shows that out of a total of 42 patterns used, pattern No.8 has the highest presence among the 42 units; Patterns No. 12, 33, and 42 have the least presence in the composition of houses. Among the most complex patterns, pattern No. 1 with 15 times the company had the least and pattern No. 18 with 40 times had the most use. The results also show that the patterns contribute in various proportions from 0.06% for patterns No. 12, 33 and 42 to 27.16% for pattern No. 8 in the sample houses.

Conclusion
The seven structural foundations of house architecture in Iranian-Islamic, including: basement, room, living room, hall, porch, platform and courtyard are clearly recognizable. Each of these seven primary units is distinct due to its purity and structural simplicity. The reason for the differentiation of the primary units is their placement in a successive series from darkness to light. For this reason, these units are turning points in marking the evolution of syntax and syntactic language of Iranian-Islamic housing architecture, and their location in the series of units generates patterns that allow them to produce a significant variety in housing architecture. In order to accept this theoretical view, field observations on houses of historical-cultural value make the existence of diversity correct. Based on factorial 7 mathematical calculations, there are 5040 possibilities for the logical arrangement of the initial space units and the production of a pattern; while according to field observations, only 42 possibilities have been used in sample houses so far. Primary units, in part or in whole, can communicate with other units in four directions. Studies show that the two directions of north-south and east-west are the most important patterns in terms of complexity and the extent of their use in Qajar period houses. Patterns together create a large, controlled space that joins together in hot conditions to create a larger space; while in cold conditions, these spaces separate from each other and create small and independent single spaces.
The coherence of the patterns in both longitudinal and transverse directions shows that the design language of the Iranian house, based on the flexibility of the constituent patterns in practice, has the ability to create newer examples. The flexibility of the patterns is affected by the integrity of the initial units, which is provided by adding and subtracting some initial units in the form of order.

Abstract
Since the formation of the Silk Road, the route has been the main route between East and West Asia. With the beginning of the age of colonialism, the process of globalization began and so direction-function of communication evolved greatly, which reached its peak in the nineteenth century and the close relationship of Iran-Japan became possible. the question of the present article is which areas or ports of Japan and Iran in the nineteenth century were used foreign trade, did the designated areas had a history and what factors affected trade. answer is that the products of the Sassanid and Safavid types reflect the political position of Japan and the trade role of other nations rather than a demonstration of the Iran-Japan relationship but in 19th century because of Imperialist pressure and needs of global trade this drastically changed .A historic review of this relationship reveals areas in Japan that were the main centers of state trade, such as the ports of Osaka and Kobe to Kyoto and Nara plains, the port of Nagasaki, and the ports of Kanagawa Bay specially Yokohama, which all of them played a similar & synchronized role in the 19th century to make trade possible from the ports of Bushehr, Lenge and Abbasi in Iran and even because of Opium trade it expanded to Taipei too. So before nineteenth century the trade in question was always influenced by the culture of closeness in Japan, but in the new era due to the pressure of imperialism and the trend of modernism gates were opened and strategic goods such as Opium exported from Iran to Imperial Japan. In order to achieve the above, artifacts and written sources along with the analysis of geographical data by using a socio-historical approach have been used.

Introduction
Since earliest times humans had trade relations to each other and so created trade routes which by developing and increasing of social complexity these routes became longer and connect more and larger societies, one of ancient and maybe first truly international routes known as Silk Road and so colonial powers (such as at first Dutch & USA) same naval routes. In result western countries connected Iran to Japan & those two as a process of modernization opened their doors to globe and started their embassies. our question is which areas/ports of Japan and Iran in the nineteenth century were used for trade with each other, did the designated areas had a history and what factors affected trade relations. Hypothesis is the same marine areas of Japan, Omura, Osaka & Kanagawa bays along different eras, Same with Bandar Abbas and Bushehr in Iran. Answering to this non-studied socio-historical title matter is very important. plus at least in Iran, because of social situation study of Qajar period always been hard and easily can effected by non-academic believes.

Main
Japan is an archipelago at the east end of Asia which as Nihongi say, made of eight main islands. Such geographic setting makes a special cultural which before anything is barred from outside and there is a self-aware hierarchy which despite shatter nature of geography, make centralize system possible. because of this cultural, Japan closed its borders to foreign relation many times such as in Heian, Kamakura and Edo periods. so despite creation of Silk Road in 119B.C Japan did not benefit it until Jingu invasion of Korea in 3th century, exactly when Sassanid artifacts alongside Korean ones found northern Kyushu & central Honshu. which most of them made in Korea not Iran. The only sources in advent of Islam are Geographer’s mention of Japan as Vaq. In early Colonial era everything changed when Portuguese and Dutch traders came to Safavid Iran and Japan at war. We do know Safavid cloth, salt, rug and even maybe marble exported to Japan by all of it foreign traders to Nagasaki and Osaka ports. By beginning of Sakoku or closed door policy of Edo period almost everything came back to first step. In 19C because of economic pressure of modernization Iran began it global trade, at first by silk and then Opium which make Iran close to eastern Asia and particularly Qing China. At the same time, Japan ended Sakoku and enters Meiji era so by the will of Nasereddin shah two countries began their relation which strengthen by Japanese conquest of Taiwan, where most of Iranian opium exported from ports of southern Iran like Bushehr and it follows by oil and Japanese exports from main ports like Yokohama and Osaka which were used during history because of their fine geography that make grow and trade easier.

Conclusion
With establishment of the Silk Road a great opportunity created for meeting of both civilizations of Japan & Iran but China & specially Korea had their monopoly in trade & relation. So least of acknowledgment and indirect relation was possible for Japan and Iran. In fact, the artifacts are more show of Japanese power & prestige than it economics. Another reason was closeness in Japanese cultural. In early colonial era were another lords of monopoly in foreign trade at least for Japan. Despite these trade happened in the same route and trade areas through history until 19C which because of Imperialist pressures new order began and so both countries began their globalization process and so for the first time direct political, cultural and economic relations were possible. The area of Omura bay and mainly Nagasaki alongside of northern parts of Kyushu to the Shimonoseki since early centuries of AD was main place for trade, the reason other than great gulfs is it nearness to main body of Asia. eastern Osaka area (or Osaka and Kobe) is a great place for establishment of a megapolis trade port and always was in use because of its route to Kyoto and other ancient capitals. We can see the same situation for Bushehr which is very close to Shiraz and other places of power to Tehran. But Kanagawa and Hormozgan areas have way better situation for making cities and ports specially their situation is more attractive for foreign traders. Because of that by modernization those ports roused immensely. Another port which grow because of 19C modernization is Taipei which used for importation of Iranian goods and have physical geography as good as Nagasaki.

Abstract
Cultural Iran according to historical evidences, archaeological remains and cultural features such as language, ceremonies and customs, it covers a wide range from Central Asia to parts of the Indian subcontinent to the Caucasus and Asia Minor and throughout the Middle East and parts of the north of Africa. Throughout the history of the governments that ruled the Iranian plateau, at certain points in time have dominated a large part of the ancient world that, while political domination, have left their cultural influence directly and indirectly in various aspects in these realms and areas. These effects on the mentioned areas are so deep that they can be considered as part of the cultural Iran. Material evidence of this influence and cultural influences can be found in the material remains left in the form of cities, as well as the character of buildings, ancient hills and historical sites and  their dependent effects related to them, including the formation and patterns of pottery, architectural decorations, as well as cultural influences such as language, clothing, customs, and mythology. In this regard, trade and exchange in the form of transfer of artificial products from Iran to other lands also has a particular importance. In this regard, some pieces of tile decorations in Qalhat site were obtained during the archeological survey of the Iranian mission, which are clear examples in this field. The ancient port of Qalhat in Oman is one of the lands that owes part of its history to the presence of the Iranian element there; According to evidences, the presence began at the beginning of the historical period of Iran, ie the Achaemenid period, and has continued for centuries. In this article, we are going to introduction this ancient port to answer the question that tile decorations obtained from the archeological survey of the Iranian mission how confirm the trade and cultural exchange between Iran and this port ? Another question is: from which center or tile production center in Iran have been these tiles traded? This research is descriptive historical type and seeks to answer the research question with an archaeological approach based on evidences and remains from survery and library studies, including refering to historical texts and other sources.

Introduction
The ancient port of Qalhat is located 15 km north of the port and industrial city of Sur in the eastern province of Oman. Qalhat is one of the most important ports in Islamic lands along with other ports such as Sohar and Nazwa in Oman and Siraf in Iran, which has been of special importance throughout its history due to their location. This port is located in a triangle area where the natural and geographical features including mountains and sea have formed. The city covers an area of around 60 hectares from the west to the heights of Jabal Al-Hijr, from the north to the alluvial valley of Wadi Al-Helm, and from the east to the sea, and from the south to the city fence wall. Cultural exchanges of 
The results of the study program showed that the first period of settlement in this place reaches the third millennium BC (Bronze Age of Oman). Also, historical information confirms the continuation of the activity of the inhabitants of this place in the Iron Age, and periods of Parthian, Sassanid, early Islamic, Islamic Middle Ages - Seljuk period - until the sunset of the peaks in the seventeenth century AD. Accordingly, we are witnessing a period of about four thousand five hundred years of residence and prosperity in this port city.

Description
At the end of its life, this port was occupied by the Portuguese during the reign of Shah Abbas I Safavid. The Portuguese at this time in order to expand their colonies and dominate on the Persian Gulf, the Sea of Oman, the Red Sea and the Indian Ocean and control the lucrative trade of these parts and compete with the Dutchs and the Britishs who at this time realized these lucrative areas, Sent warships and units of their navy to these areas and occupied important areas including several islands and ports, which can be mentione areas such as Gambron port - Bandar Abbas - Hormoz and Qishm islands in Iran and ports of Qalhat, Ras al-Hadd, Sohar, Nazwa and Qoryat in Oman. In 1639, following the revolt of the inhabitants of the people of Qalhat against the occupiers and the recapture of the city, the defeated Portuguese retreated using explosives placed in the city on one side and with the cannons of their ships on the other targeted the city with severe attacks and completely destroyed it , so that except for the tomb of Bibi Maryam and the water reservoir of the city that was adjacent to it, all urban structures were destroyed. Some have attributed the non-destruction of the tomb to the Portuguese respect for Maryam’s name. In any case, this destruction was so widespread that it led to the destruction and abandonment of the people, and thus this important port disappeared for ever.
Following the conclusion of an agreement between the Cultural Heritage Research Organization of Iran and the Ministry of Archeology and Culture of the Oman, Two research programs were conducted in the Qalhat area under the supervision of the author. During the first season in the winter of 2007, this area was archaeologically surveyed and all its architectural remains were mapped and documented. In this regard, the important places of the port, including the areas around Bibi Maryam’s tomb and Qalhat Mosque, were surveyed with more focus.  In the second season, in the winter of 2008, based on the knowledge obtained from the archaeological survey conducted in the previous season, a place was selected for excavation, which resulted a building with the use of a khan or travelers’ residence.

Conclusion
One of the sites surveyed by the Iranian archaeologists is the remains of the ruined Mosque of Qalhat, which is located in the southeastern part of the city and overlooks the sea. This mosque has a square plan and was constructed with materials including rubble and light coral stones, like other buildings in the city, and from the surface artifacts, it can be seen that it was decorated with a lot of decorative elements related to architecture. The tiles used in this building are of the star and cross type in turquoise and green colors.
The most important building in this city is the tomb of Bibi Maryam, which has a quadrangular building with a crypt tomb; A building that, as mentioned, has survived the pervasive destruction of the city by the Portuguese. Bibi Maryam, the wife of “Ayaz”, the ruler of the Ilkhanid period, was in Hormoz, who sat on the throne for 2 years after the death of her husband around 696 and 697 AH.  According to the available evidence, parts of the inside and outside of the tomb were covered with tiles. Except for a few pieces, none of the tile decorations are left on this building, at now, but existed evidences on walls indicate that many parts of the building are covered with different types of tiles.  The study indicated that, pieces of several types of tiles were used as ornament for the tomb. In this article, we have introduce the tiles obtained from the study and discussed how to transfer these cultural materials in the form of trade and compare and them with similar examples in Iran. 

Abstract
Sasanian Silver Bowl at the National Museum of Iran, known as the “dancer-musicians scene”, has been one of the museum’s most archaeological works for the past sixty years. According to Ali Sami, this bowl was purchased in 1334 (1955); it is attributed to the north of Iran (Kelardasht of Mazandaran). The palm-shaped head of this bowl shows four dancer-musician-singers with four different well-known musical instruments as well as a figure of a pheasant in the center. In all previous scholarly works, as well as in the many exhibitions in which this bowl has been displayed, this work has been referred to as the motif of the “female dancers-musicians”. However, doubtful interpretations of musical instruments of the motif can be found in the same scholarly works. Obviously Iranian scholars to the internally held exhibitions have followed previously mentioned works. The author will first challenge the “femininity” of these four dancer-musician-singers and will testify the view that three of them are only masculine. Secondly, I will present a new proposal to the readers with a different interpretation of these Iranian music instruments. Also, the author considers this bowl to probably be a heritage from the Persian Gulf (southern, not northern Iran). Furthermore, I will also focus on the identity of these dancer-musicians in such a musical group scene as “Indian gypsies” or at least inspired by such a musical style. The author will also refer to two other lesser-known similar bowls of the Museum. Meanwhile, the author will present a new perspective on the date of this silver object which is based on its motif details and two more Silver Works at the National Museum of Iran. In this comparative study, I will draw a line between the three motifs (of the bowls, especially two of them) based on the two seasons of “winter and spring (or summer)”!

Introduction
Much has been said and written about the Persian Gulf. Since more than 500 years ago until now, about cultural landscapes, art, music, clothing, food styles to different harbors and etc. through foreign travelogues and Iranian documents can be attributed to colorful valuable data on the Persian Gulf. Archaeology has also testified a large tangible data about Iranian identity over the Persian Gulf. Pre-historic objects to the valuable inscription of Darius the Great obtained from the Suez Canal to other archeological finds from Bushehr, Siraf, Kharg, Qeshm, Hormoz, etc., are proof of this claim. Zoroastrianism legacy in Saudi Arabia and especially Yemen to recent Sasanian coins from the United Arab Emirates, Sasanian fortresses in Oman (cf. Potts, 2012: online)... can be proof of our historical ownership of the Persian Gulf.
Nevertheless, the article stresses on a review of a Sasanian magnificent artistic relic in the National Museum of Iran. This masterpiece frequently has been referred for at least the lasxty years. This significant object has been displayed in most of exhibitions from the inside to the abroad. This Sasanian heritage has been published in most of the catalogs of the National Museum of Iran and international exhibitions. This very beautiful Sasanian work, “silver bowl” known as the “scene of dancer-musicians” with registry number 1332, weight 575.7, diameter 22.55 cm, and height 7 cm, obtained from Kelardasht (?), Mazandaran.

ConclusionUndoubtedly, the Sasanian silver bowl at the National Museum of Iran can be studied from a new perspective. This view can challenge all previous scholarly works from two different aspects.
First, the musical instruments portrayed on this work can testify to its interrelationship with the shores of the Persian Gulf. For example, Castanet or Sinj is a typical instrument. There is a golden shipwreck’s photo (with eight musicians-singers), has some similarities with the silver bowls of the National Museum of Iran, on the website of Asian Civilizations Museum in Singapore.6 According to the website, the work has been discovered from a Persian Gulf bound ship drowned near Indonesia. However, the author has doubts about authenticity of this report! 
Although there are few written archaic texts but these instruments have been valid from generation to generation in Iran as endorsed by sources in Sasanian, Post-Sasanian, oral history as well as archeological documents until they have reached our time. 
Most Post-Sasanian sources have preserved valuable information about Arghanun, sorena, lute (barbat) and even chime.7 Although Zoroastrian texts do not help on such a topic but the story of Khusraw ī kawādān ud rēdak (Oryan, 2004: 58) mentioned some of the best musicians: “harp-players, lute-players, wan players,8 tambour players, and reed players.” 
Chime (cf. Ibn Sina)9 is one of the oldest musical instruments in southern Iran. The Haft-Joush (seven parts) chime was also one of the most common of these musical instruments; the Indian type of which (made of bronze) had a special reputation in Bushehr (Darvishi, 2004: 540,32). Type of the short handled and tied to the fingers have been (and still are) the most common chimes in southern Iran (for the same instrument, see: Gunter and Jett, 1992: 191).
Another important fact is that the production and control of the melody with these four instruments were very difficult for females (women); three of them (bowl) still considered male instruments. In Taq Bostan too, sorena and a kind of arghanun (or bagpipe, maybe nay-e anban) are played by men where females are depicted as tambourine and harp players (farmer, 1964: 96). Both of these latter instruments have always been depicted and described in this way (female).
So, the gender of the musicians will be the second key point of this object. It is as if the previous works did not pay attention to the connection between the “type of instrument and the type of gender” which, according to the tradition, they were at least skilled players. 
The story of “ Khusraw ī kawādān ud rēdak “ (Oryan, 2004: 96) describes “a sweet-singing-dancer and a beauty with big breasts, wasp waist, black and long hair ...”. Here are two questions:
1. Whether the female musician-dancer figures on the Sasanian silver legacy, with big breasts, slim waist and charming disheveled hair (National Museum of Iran, cf. fig. 6) cannot be a seal of endorsing the above-mentioned Pahlavi text? If that is the case, which I believe it is:
2. Isn’t this (description) contrary to the motif of the musicians of the silver bowl at the National Museum?
This issue of course according to the type of make-up and body shape confirms that three of them are males. Therefore, in the dance-music scene of other objects, the shawl on the breast (or part of it such as Bishapur mosaic), from behind (such as the silver decanter at the National Museum) or above the head like a sunshade (fig. 9) can be seen. Here, the shawl is skillfully placed on privy parts (low body) by the craftsman in order to have observed Iranian ethics (of course with partial rotation of the body). If in other objects, the shawl plays a role in covering the breasts of women, here it covers probably their low bodies.  This is not very compatible with Roman art!
In the Sasanian silver decanter at the National Museum, despite a kind of decorated forehead, the hair of the musician is hung from both sides towards the shoulders but here typical long-braided hair can remind us of Indian style which impacted the Persian Gulf coasts. However, no trace of the hair of the above mentioned musicians can be seen here, and they wear a head-gear (with two different logos on the forehead in pairs) that is fastened with a bandage under the throat (it is unlikely to be a hair strand). On this bowl, the whole body (with details) is portrayed in front and the head is turned to another side (profile), something that does not occur much with other works. The highly balanced and professional limbs of these dancer-musician-singers indicate their affiliation with a professional group. The beautiful and balanced body as well as the “hairless face” of these three male musicians plus one female, is thought to be one of the reasons for calling these four dancers females.
Furthermore, a theme rarely seen in Sasanian art is a “harmonious music group”  (male and female) scene. Even in the royal hunting scene of Taq Bostan, less resemblance (coordinated group) can be found to this bowl.  The musicians of Taq Bostan cannot be called a scene of a group performance.
Another similar silver bowl (fig. 10) with the same motif (four dancer-musicians from Kelardasht) at the National Museum of Iran published by S. Ayazi (2005: 92-93) already. These two bowls differentiate each other by some significant details which have never been studied. In the second bowl, the relatively “thick cover” of the musicians along with the figures of the “birds” is very significant. It seems, to me, that the first one reflects summer or spring season but the second one clearly recalls the winter season. Figures of different birds (which can be discovered in the spring season) is a part of the claim (the second one). There is also a third bowl with the same scene, in the National Museum, which I will write about in more detail in the future.
The author believes that the motifs of these three bowls are merely radiant of a “simple secular feast” (cf. Boyce and Farmer, 1990: 55; also: Gunter and Jett, 1992: 200). Obviously, the Sasanian heritages can never have been recorded without religious traces, which subconsciously ruled the artist’s mind. Hence, the meaningful name of the owner of the first bowl  (Farrokh-hormozd not windad-hormozd) to the design of the black “ten” leaves of the palm branch, the pearl ring around the pheasant in the middle of the object, the number of pearls of the pearl ring, two ribbons and also the three branches in the beak (Glory, triple social casts  or the doctrine of the Zoroastrianism) are part of this claim.
 Although the existence of motif of birds and animals in Sasanian art (rock, art, bullae, etc...) is a normal subject, but the figure of a pheasant (center of the bowl) can remind us of the “Khorasan Art School” that goes as far as China (Akbarzadeh, 2020: 267). 
The author believes that there is no connection between this scene and the one from Roman legacy of Dionysian or the goddess Anahita (Catalog of Wien, 2003: 233; Gunter and Jett, 1992: 27), as mentioned in all previous works. The following reasons can support me to challenge the previous works: “the typical oriental type of dance of these dancer-musicians, which is evident from their body shape, the pheasant figure most unrelated to the Zoroastrian goddess, the partial nudity dancers, which is not compatible with the officially known Sasanian art (but they are covered on the second bowl), their instruments, the absence of any bold religious symbols etc... supposedly for their body shape (type of dance), type of head-bands, shawl pattern, typical southern chime (with base, like pliers), dancer-musicians in group scene ...” Also, the author points the finger at India, not the Roman heritage for such a coordinated group performance that Sasanian art lacked (cf. Boyce and Farmer, 1990: 60). 
The Indians have always been known as female-males dancer-musicians in group form (unlike individual Sasanian dancer-singers). Also, the figure of the peacock (bowls 2-3) can support this claim. Moreover, the presence of Indian musicians-dancers in the Sasanian period is a well-known issue. It is obvious that Bahram V (Gur), after treating the mental condition of the Iranian society, ordered many musicians from India to come to Iran and play in public. These musicians are known as “gypsies” in the history of Iran.10 In fact, the author evaluates this group of naked (and partly-covered) dancer-musicians (with a completely different body shape) on these Sasanian bowls as Indian gypsies. Their half-nakedness cannot be an Iranian tradition in dance. In a work, about such instruments, attributed to Ibn Khordadbeh (Mallah, 1963: 28; Sami, 1970: 49) narrates that: “Iranians usually played the lute with the flute and the tambourine and the sorna with the dohol (drum) and mastaj (chime) and the senj.” 
The author also believes that due to the to the accuracy in construction and high technic of these valuable bowls and the processing of artistic symbols, especially such a dancer-musicians in group scene, its attribution to the eighth century AD., Post-Sasanian period (given the socio-political situation of Iran), is questionable. If this bowl(s) was made in the geographical boundary of Sasanian Fars province (including parts from Khuzestan to Fars and the whole of present-day Bushehr province) (which is strongly believed to be the case), the eighth century AD. was the most difficult period of this part of the Persian Gulf. Furthermore, the artistic details of these objects are never less, if not more beautiful than the objects of the sixth century AD. (cf. Lawergren, 2009: online). The skill in the inscribed needle-shaped of the owner’s religious name, the exact size of the body of the musicians, the branches of the grape, colored lace and other details indicate that the creation of this work can be even brighter than the eighth century AD. 
Despite this, a fundamental problem will remain and that is the type of cover of the dancers on these three bowls. This coverage can mean a “seasonal difference”, that is likely to be the case. Based on this one, we should focus on the eighth century AD. The author suggests that the second bowl (covered dancers) can be a reminder of Mihragan Festival at the beginning of winter and the first one (naked) can be reminiscent of Nowruz Festival (or a summer fest). This six-month gap (between two seasons) is the least reason why the two group of the two objects can be considered the same. If we cannot opine about the time of Mihragan Festival, but the time of Nowruz Fest was not fixed at the beginning of spring in the Sasanian calendar. This event is related to the early Islamic periods and this one does not contradict the eighth century. In short, that discovery of this bowl (for whatever reason) from northern Iran will never be an excuse to consider its origin as northern, and of course this is not surprising in archeology.

Abstract
One of the most critical found objects from the site of Shahr-i Sokhta are lapis lazuli stones and beads, which were used as stone jewelry and ornaments. One of the site’s most significant archaeological and archaeometry topics is the way of manufacturing and types of stone structures into these objects. The Shahr-i Sokhta’s lapis lazuli beads manufactured with flint borers are in the forms of lens, lozenge, circle, etc., and were used as jewelry and ornaments such as bracelets, anklets, necklaces, etc. The main discussion in this research is recognizing the structure and studying the mineralogy of lapis lazuli beads discovered from Shahr-i Sokhta. Hence, by using laboratory-device methods such as petrography of thin sections, X-ray energy diffraction microanalysis, Raman Spectroscopy analysis, and gemology methods, this research studies the structures of three samples of lapis lazuli beads and stones of Shahr-i Sokhta. The results of laboratory studies show that Shahr-i Sokhta’s structure of lapis lazuli stone consists of lazurite minerals with a high percentage of calcite mineral impurities, which causes a reduction of transparency and purity of the lapis lazuli stones; also, elemental studies represent the presence of lazurite minerals. Raman structural and gemological studies show the structure, the amount of absorption coefficient, and its specific weight in the main structure of lapis lazuli stone. Chemical and structural studies indicate that the stones are similar in terms of composition.

Introduction
Shahr-i Sokhta is one of the most important and key sites among Bronz-age sites in southeast Iran’s archaeology (Biscione et al., 1974; Tosi, 1968, 1969, 1973; 1976; Tosi and Piperno, 1975; Savatori & Vidale, 1997; Piperno & Salvatori, 2007). Through excavations during different years up to now, a vast majority of semiprecious Stones and jewelry have been discovered; some of them are healthy beads in the form of necklaces, bracelets, and anklets, while others are half-worked beads as well as raw stone and blocks (Foglini, 1998). The jewelry is lapis lazuli, agate, chlorite, turquoise, limestone, flint, jasper, marble (calcite and aragonite), quartz, green tuff, and chert; that one of the most significant of them is lapis lazuli which was brought to Shahr-i Sokhta as a result of the trade from other regions. lapis lazuli stone in various forms and shapes is the most discovered abundant cultural material in Shahr-i Sokhta (Sajjadi, 2005, 2007). The discovered lapis lazuli are healthy and semi-worked, as well as raw and discarded material. The archaeological studies have demonstrated that the raw lapis lazuli blocks were imported into Shahr-i Sokhta, and then they were changed into various artifacts by artisans (Farzin et al., 2019). Hence, recognizing the structure and method of manufacturing the discovered lapis lazuli beads from Shahr-i Sokhta could be one of the most important topics for archaeologists. The archaeo-gemological study is a field of archaeometry that investigates and recognizes the structure and method of manufacturing and polishing these semiprecious Stone ornaments and jewelry. Archaeo-gemological studies examine minerals, gem materials, and jewelry, which were used as ornaments, decorative objects, jewelry materials, etc., in particular eras and places of the ancient world (Hatipoglu & Guney, 2013; Rapp, 2009; Dominguez-Bella, 2012). Therefore, this research based on Archaeo-gemological studies investigates the preliminary lapis lazuli stone jewelry produced in Shahr-i Sokhta.

Material and Methods (Samples)
The selected samples in this research include three pieces of lapis lazuli discovered from the archaeological survey of Shahr-i Sokhta. One of the samples is a raw material with a small incision that had been discarded as waste (SH-L1). The other one is a rectangular object with grooves in its width, which was broken during use (SH-L2), and the last one is a tiny bead; all three are studied in this research (SH-L3).

Methods
Microscopic thin section petrography (OPM) is administered to examine the samples under a polarizing microscope. The device model used in this research is James Swift, made in England.
The elemental Micro-analysis EDX method is applied to recognize samples chemical combinations. This examination is conducted through EDX devise coupled with a field emission electron microscope (FESEM) manufactured by Tasken company, model MIRA3TESCAN-XMU.
For structural investigation of the samples, this research uses Raman spectroscopy examination through (Takram) P50C0R10 model device, Taskan company in Raman laboratory. This device has a laser wavelength of 532nm (Nd: YAG Laser), and the range of Raman shift RS is 100-4600.
Moreover, this study uses gemological methods such as specific weight and refractive index to identify the samples.

Results
Petrography
According to the petrographic studies of the lapis lazuli samples under a polarizing microscope, blue lazurite minerals are seen with white calcite.
 
Raman Spectroscopy
The obtained spectra from this chart are compared with the reference spectrum at http://www.rruff.info This comparison indicates the existing lazurite in the stone structure of Na3Ca(Si3Al3)O12S. There is a Raman spectrum in the range of 546 cm-1, 1092 cm-1, and 254 cm-1, and the intensified spectrum is high in the range of 546 cm-1, considered the main spectrum.

EDX
Micro-analysis (EDX) Obtained spectra in the formula of these stones represent the amount of silicon (19/61 and 19/11), aluminum (7/14 and 7/21), magnesium (7/98 and 6/73), calcium (4/98 and 4/94), and sodium (3/46 and 3/13) elements with the highest abundance.

Gemological Analysis
This part investigates these lapis lazuli’s mineralogical features through two refractometer methods and the determination of specific weight. 

Refractometer
Among Shahr-i Sokhta’s studied samples, this research has selected three lapis lazuli samples to study. For investigating, first, one drop of special liquid (REFRACTOMETER LIQUID-Nd 1.81) is poured into the location of the samples; second, the flat sides of the gems locates on the oil. Then, by turning on the device lamp and closing the deflectometer cap, one could obtain each sample’s refractive coefficient measure by reading the refractive coefficient. The type of the studied sample has been identified by measuring the refractive coefficient of the samples and comparing obtained numbers with the standard table of gems (GIA- GEM PROPERTY CHART). The refractive coefficient of 1.50 is related to lapis lazuli stone.

Determination of Specific Weight
One of the quick identifying ways of the gems is the determination of their specific weight, which causes no damage to the gems. To obtain the particular weight of each mineral or gem, first, they are weighted in the air and then in the water. Next, by using a formula, the amount of specific weight is calculated. The particular weight of the discovered lapis lazuli samples of Shahr-i Sokhta is 2.1-3.3. 

Conclusion
Microscopic investigations based on the thin section petrography show that the structure of studied lapis lazuli is lazurite mineral type with calcite minerals. In microscopic images, Lazurite minerals clearly are blue, calcite minerals in the stone texture are white, and pyrite minerals rarely can be seen in the studied stone texture. Identifying the existence of a significant amount of calcite and a poor amount of pyrite in the lapis lazuli structure represents the amount of impurities in these stones. Furthermore, elemental analysis of the three lapis lazuli indicates that there are other elements with the highest frequency; these elements are silicon (20/95 and 20/67), aluminum (7/80 and 7/63), magnesium (7/28 and 8/52), calcium (4/94 and 5/33), sodium (3/34 and 3/74) and sulfur (0/66 and 1/09). In fact, lapis lazurite is a blue stone whose chemical composition is variable, and its basic composition is mineral lazurite consisting of aluminum, calcium, and sodium silicates. Lapis lazuli consists of several different minerals, such as sodalite, hauynolith, calcite, pyrite, and lazurite, which are lapis lazuli’s main components. Fewer white calcite spots and more yellow pyrite in the lapis lazuli indicate the best quality of the lapis lazuli. In table 3, silicon element (29.87%) and calcium element (12.26%) are the most amounts of compounds in the Shahr-i Sokhta lapis lazuli structures. The identified chemical compositions of the lapis lazuli in Shahr-i Sokhta are a high amount of calcium and a low amount of iron, which indicates the lapis lazuli structure of this site has a high calcium impurity and low pyrite impurity; this issue could be confirmed through petrography studies. Finally, this analysis represents the correct recognition of the composition and type of used stones in manufacturing ornament objects of Shahr-i Sokhta.
The element percentage of obtained spectra is clearly determined, indicating the main composition of lapis lazuli. The elements represent the chemical structure of a lapis lazuli, a lazulite mineral type with a high calcite impurity percentage. In addition, this study examines the three pieces of lapis lazuli samples through Raman spectroscopy; two samples represent almost similar peaks in the range of 546 cm-1 and 1092 cm-1, and only one sample shows a peak in the range of 546 cm-1. The investigations represent that based on the lapis lazuli studies using the Raman, the lapis lazuli in the mentioned ranges shows an almost significant peak. The number of elements and obtained spectra in these two spectra are almost similar.

Abstract
Despite the importance, position and high role of the city of Hamadan in the political, economic, social and cultural developments of Iran during the Qajar era, targeted studies that determine the spatial organization and social structure of this city during that period have not been carried out, and there are many questions regarding the nature of the changes in the context. Its history remains unanswered. The current research seeks to answer questions about the transformation and development of the spatial structure of Hamedan city during the Qajar era by relying on written sources, architectural works and archaeological evidence. In order to achieve this goal, while using all the written sources related to this city in the mentioned period, the changes of the urban context and the structural characteristics of its spaces were determined and the factors affecting the growth and development of the city were determined during this period. The result of the research made it clear that due to its ancient background, special geographical location, benefiting from suitable environmental capabilities such as abundant water resources, and also due to its location on the path of important trade-pilgrimage routes in the Qajar period, Hamedan was one of the cities with social and economic importance and status. It has gained merit and accommodates a relatively large population and has attracted the attention of various social groups, especially merchants. Thus, suitable conditions have been created for the construction and discovery of numerous architectural works and monuments with different functions (defense facilities, residential neighborhoods, squares and plazas, markets and caravanserais, mosques, schools, baths, churches, etc.) and the urban space, especially in aspects The south and southeast have developed and expanded significantly.

Introduction
Cities are one of the main centers of the emergence of civilization and valuable cultural treasures, without knowing them, it is not possible to study the history of various developments in human life. For this purpose, the study of the cities left from the past plays a significant role in understanding the political, administrative, social, economic and cultural structure of the societies that created them (Krimian, 2014: 121-111) and can provide clear horizons in recognizing the physical, social and cultural structures And reopen the past civilizations to researchers (Krimian and Seyedin, 2009: 69). The study of the ancient living spaces of Iran and the historical contexts of the cities is a necessity that has allocated a part of the scientific activities of archaeologists. Although the historical fabric of Hamedan has suffered a lot of damage due to various reasons, including indiscriminate and irregular constructions, but a number of its historical and valuable buildings have survived the ravages of various times and manipulations. Recovered and recognized to a great extent. Hamadan is one of the few historical and ancient cities in the country that has survived historical developments with strength and has preserved its historical context to some extent. Undoubtedly, Hamedan’s location on the path of communication routes in different eras, as well as its special geographical location and the benefit of environmental capabilities are the main reasons for the continuity of this city throughout history. Fortunately, valuable elements of the architecture of the Qajar era have survived in this city, and by studying them, it is possible to analyze and restore the spatial structure of Hamadan city to a great extent.
The purpose of the Research: The main purpose of the research, the results of which are presented in this article, is to find out how the physical structure and spatial organization of Hamadan was created, developed and transformed by relying on architectural works, archaeological evidence, written sources and visual documents left from the Qajar period.
Research Questions: In this study, we have attempted to answer questions about space structure, different types of architectural works, scope and physical realm, as well as the extent to which different social groups have been influenced by the space organization and architectural works of Hamadan in the Qajar era.
Research Method: The study presented in this article is historical -analytical in nature and content, and has been conducted in both field and library methods.
The original text of the previous article consists of several different sections. In the discussion of the research background, the most important studies on the historical context of Hamadan have been emphasized with the emphasis on the Qajar era. In the context of the structural characteristics of the Iranian cities in the Qajar era, the main characteristics and components of the identity of Iranian cities in the Qajar period as well as how the structural characteristics of Iranian cities from the Safavid era to Qajar has been discussed. The next section of the article is analyzed and explained by the Qajar Space Organization in the Qajar era based on written sources. Travelogues and historical texts from the Qajar era have formed the most important study sources in this section. In the other section, the urban spaces of Hamadan during the Qajar period are discussed. In this section, relying on written sources and existing architectural evidence, some of the most important physical and historical spaces recovered by the Qajar era of Hamadan, including defense facilities, residential neighborhoods, inter -and -outskirts, squares and squares, commercial spaces and markets And the disposal of sewage, mosques, baths, churches, and so on. It was also known that marketers and traders were more involved in the phenomenon of the city’s architectural works in the Qajar era than other social groups.

Conclusion
In the present article, it was attempted to find out what the space structure of Hamadan had in the Qajar period by relying on the written sources and existing architectural works. With what was done, it turned out that the city was forming from three internal (city center), middle (urban areas and neighborhoods) and exterior (fence and suburbs). Hamadan Space Agency is also influenced by the pattern of Islamic cities of Iran, has a citadel (government, bureaucratic and administrative headquarters), Jame Mosque (Religious Center) and Market (Economic Heart) and other urban elements (schools, blessed shrines, intra city caravans, baths And ...) Somehow they were related to these three. Relying on written documents, it can be said that areas outside the city’s defense walls were exploited for agriculture and horticulture. During the Qajar period of Hamedan, with the center of the mosque and the bazaar in the south and southeast direction, it expanded and some new neighborhoods, along with urban elements such as mosques, baths, etc., are being constructed in this area. Most of the reasons for the expansion of the city’s texture in this area can be considered as the proper slope of the land and the lack of natural effects that could have been a barrier to construction. Due to the flow of the four rivers inside and outside the city during the Qajar period and their annual floods that occur as a result of heavy and long -term rainfall, as well as the slope of the city in the south -north, as a result of the flooding of the northern parts, as well as the natural complication. The so -called Mosalla hill in the eastern part, which prevented the development of the city’s physical structure, was the best way to develop it, southern and southeast side, along the rivers in the inner -city rivers of al -Wawsger and Davin. According to written and illustrated documents as well as existing architectural works and archaeological evidence, it can be said that the city of Hamedan in the Qajar period from the north to the Goulan Heights, Nazarbaig and Shalabafan, from the east to the neighborhoods of Imamzadeh Yahya and Zandis, from the West to the Bonehbazar and Sabadbafan neighborhoods were confined to the Kolapa, Doroudabad and Doguran neighborhoods from the south. Also, the result of studies on the role and influence of different social groups and classes in the formation of Qajar architectural works of Hamadan indicated that the traders and marketers of the marketers top the list of builders and sponsors of various buildings (religious, commercial, residential and public).

Abstract
Inscriptions in the decorations of building of the Islamic period have been noticed by artists since the early Islamic centuries. Overtime, inscriptions are damaged by various factors and need to be restored. Considering that every year in the country, a large amount of restoration operations are carried out on damaged historical monuments, including inscriptions. It was seen through the investigation that in most cases the restorations are tasteful and sometimes incorrect. In order to find the most important causes of incorrect restoration in written inscriptions, the qualitative method was used, and the grounded theory method was used to analyze the data. This research is practical in terms of purpose. The data was collected through field observations and interviews with 12 people related to the restoration of inscriptions and by purposeful sampling, and the data continued until theoretical saturation was reached. The results of the research showed that in addition to the lack of criteria that agree with the theoretical foundations of restorations, due to the prominence of the calligraphy and category, factors such as self-centered empiricism, the variety of viewpoints, knowledge and awareness of the traditional master craftsman and the rules of restoration and the lack of the artistic perspective of the traditional master craftsman. For various reasons, inscriptions have led to incorrect restorations, and of course, the lack of training courses by the institutions in charge of restoration has also been involved. Also, the variety of approaches in the restoration of inscriptions and lack of attention to the rules governing the art of inscriptions are considered as the most important consequences of the restoration of inscriptions.

Introduction
With the beginning of the Islamic era and the restoration of human and animal depictions, the use of inscriptions with religious, literary and historical themes reached its peak with various calligraphy methods and styles. This enduring art that is inscription is still performed by artists to this day. Inscription like other historical works, suffer from various physical, chemical, biological and human damages, and from various perspectives of value, aesthetics, originality, legibility, unity and integrity they suffer serious damage. Therefore, despite the important characteristics mentioned about this category of written works, the need to pay attention to this category of work is revealed in restoration operations. The importance of paying attention to the issue among other valuable historical and cultural work is important in the sense that there is a lake of criteria in accordance with the theoretical foundations of restoration, for the restoration of areas lacking in this category of valuable written works. Although in most cases, the restoration of this category of works is often done under the supervision of restoration experts, the approach and methods of doing the work in different examples are not subject to scientific principles and are mostly tasteful and sometimes incorrect and without regard to the ruling principles, they are restored on the art of calligraphy and inscriptions and it has caused distortion and sometimes loss of the of the inscription, its values and message.
According to examples of the restoration of written inscriptions ,when the restoration of a written inscription is done incorrectly , in fact, readability , integrity and beauty ( Beauty is in  harmony , balance, proportion , even beauty in observing the rules and recognizing the values and materials have been used (Qutbi, 1352, 31) the inscription is distorted and the audience , when viewing an inscription that has been incorrectly restored , gets the visual pleasure of seeing the harmony and connection between the words in an inscription will bs deprived. In fact, carrying out the restoration operation should reduce the inconsistency caused by the lack of space and help to read the work better.

Method Research
The upcoming research is applied research in terms of its purpose, because the researcher seek to obtain information that can be used in practical situations or solve a problems by means of them and obtain a solution to a problem. This research is a qualitative research in terms of method and in terms of data collection, it is based on field studies, interviews, observation and collection of documents and texts within the framework of the grounded theory method. The interview was conducted with the purposeful sampling method and until the theoretical saturation was reached 12 people were interviewed among the restoration experts, inscription artists and master traditional craftsmen. Grounded theory and systematic coding were used to analyze the interviews.

Research Background
Although restoration of inscriptions has always been one of the concerns of restorers, it seems that a comprehensive, coherent and effective study has not been done in this field. For example, the following can be mentioned: the Scientifics specialized and professional restoration community has not restoration of inscriptions of mosaic tiles in Iran (Soleimani et al., 2014), researchers have criticized the methods of restoration of mosaic tiles but there is no mention of the causes of its correct restoration. Also, sources such as Quchani (1365: 51), Bler (1394: 30) and Qader (1391: 86 &103) mention the non-original restorations of the reason for that has not been discussed. By checking the databases related to non-Persian theses, unfortunately, no example similar to the subject of this research was found. In line with above investigations, Persian sources were also carefully checked. 

Conclusion
Inscriptions are one of the most important and valuable works of the Islamic period and they are a living document from different perspectives such as historical, artistic etc. Restoration of inscription has always been one of the concerns of restorers. But the results of the interview and data showed that the main factor in the variety of approaches in the restoration of inscriptions and the lack of attention to the rules and regulations of inscriptions in the process of restoration operations is self-centered empiricism. Among the traditional craftsmen and even the scribes who are somehow related to the restoration process of the inscriptions, ignorance of the restoration rules or even ignorance of the different aspects of the inscriptions can be seen. Also, looking at the conducted interviews, it can be pointed out that the role of the custodian institutions in relation to the restoration of inscription is weak, unfortunately, in this field , training courses are not held for the inscription writers and traditional masters, and it seems that by holding training courses and obliging inscription writers and traditional masters to participate in these classes, recognizing the values of the works and observing various aspects in the matter of restoration are institutionalized. Even though in most cases, restoration operations are carried out under the supervision of restoration experts unfortunately, due to the lake of standards in the restoration of inscriptions shortage areas, diversity of approaches in the restoration of inscriptions and even incorrect restorations can be seen, also, it seems that one of the challenges in the field of protection and restoration of written inscriptions is the theoretical issues related.
To the restoration of this category of valuable written works: because the theoretical reliance of the theoretical discussions of conservation and restoration is often focused on Western theorists and their studies and theories, which have been explained from the viewpoint of a group of researchers and following the statements of summits, charters and such. Especially, when these theoretical rules are put forward in a general way and without considering the spatial, temporal and cultural background, they usually face constructions. In order to correct and solve these problems, attention should be paid to the local knowledge, which can be a way forward in view of the existing knowledge in the field of Iranian architecture and the rules governing the art of inscriptions, and in order to add new concepts and foundations to the field of conservation knowledge and restoration can be considered. 

Abstract
Since there are few works of painting from the Seljuk period, and on the other hand, most of them were written without data and place, so there are no common opinion about most of the painting works of this period. On the other hand, because most researchers, do not use the correct scientific method in their research, it adds to the existing problems in this field. One of the painting works of this period, which is the subject of this research and has a writing data, is the Al-Tariaq book attributed to Galen, which has written in 595 AH/1199 AD, written and kept in the National Library of Paris. Due to the fact that the place of its writing is not included in this manuscript, there is a difference of opinion about where the said version was written and illustrated. This version has been attributed by different people to different places such as Iran, Jazireh, Dyarbakr, Mousel and Baghdad. Therefore, the basis of the main problem of the current research is the location of the place of writing and illustration of this manuscript, which is analyzed and criticized by descriptive-analytical and comparative methods based on library studies, and the views of researchers will be examined with comparison, it will be shown that the version of Al-Tariaq cannot be attributed to any other country than Iran. By examining and comparing the illustrations of this book and other Iranian works of arts, especially pottery and metalwork, it can be said that the view of most researchers of the illustrations of Al-Tariaq book is more similar to the way of recording Iranian art than to Iraq, so, it can be said that the origin of this manuscript is Iran and other views are incorrect. 
Keywords: Al-Tariaq, , Iran, Jazireh, Baghdad Method, Mosul.

Introduction
Since there are few works left about book painting and illustration in Seljuk period Iran, and on the other hand, most of them are without date and place of writing, so most of the works of painting of this period are discussed and disputed. Apart from these problems, the failure to apply the correct scientific method and also the involvement of some prejudices, which of course are not worthy of a scientific research, have caused the existing problems in the field of painting in this period to be added, one of the works of this periods, which fortunately has a writing date, is a copy of the Al-Tariaq book attributed to Galen, which was written in 595 AH and is kept in the National library of Paris. Due to the fact that the place of writing is not mentioned in this manuscript, most of the researchers, if it is found in the text in its entirety, argued with very weak reasons and without scientific basis that this version was written in the Jazireh or Mosul and has nothing to do with Iranian art, so the purpose of this the research is a complete review of the writing and illustration of the Al-Tariaq book.
Research question and hypothesis: The main proposition of the research is to locate the place where the manuscript of Al-Tariaq was written and illustrated in Paris, and by examining the artistic style and the role of the materials used in the illustrations of the Al-Tariaq book, the question is raised, which one of the most similar styles and materials of this book are there art school? By assuming the connection and compatibility of the motifs illustrated in the mentioned book with various works of art, including the paintings of Iran’s enameled and gold-colored pottery, as well as the motifs used on the metal works of the Seljuk and Khwarazmshahi periods, it is possible to determine the place of its writing and illustration, attributed to Iran. 
Research Method: The research method in this research is a descriptive-analytical and comparative method based on library studies in criticizing the views of the researchers about the Al-Tariaq manuscript, which is related to the enameled and golden pottery and also the role of the materials used on the metal works of this period in Iran. The research problem has been discussed. 

Inroduction of the Manuscript of Al-Tariaq
The book of Al-Tariaq is a translation from the book of Galen, a Greek physician and pharmacist who lived in the second century AD. This book was translated from Greek to Arabic by Ibn-Ishaq in the 9th century AD. The subject of the book is written about toxicology and antidotes, which the author narrates with legendary stories. There are two illustrated versions of this book. The first version was written in 595 AH and is kept in the National library of Paris. The second version is undated and it is attributed to the middle of the 13th century. This manuscript is kept in the Vienna National Library. In this research, the dated version of the National library of Paris will be examined. This version has 12 images, the first of which begins with an image that is repeated twice. In the middle of the painting, a woman is sitting holding a moon crescent and two people are standing on either side of her. This page is surrounded by a frame made of intertwined dragons. 4-winged people can be seen on the four sides of this frame (Fig 1). After that, nine doctors of the period, including Galen himself, have been settled along with their names and biographies (Fig 2).

Conclusion
Based on the investigations and the comparison made between the pictures of Al-Tariaq book with the paintings of Zarinfam enamel pottery and Iranian metal vessels, it was found that there is a complete similarity in terms of stylistics, the way the pictures are drawn and the composition between the Al-Tariaq book and these works. Therefore, attributing this manuscript to the Jazireh is incorrect. The only reasons mentioned by some researchers are human monographs and other interwined dragons, however, if it is mentioned in full, similar to it has been seen in other regions, the image of two interwined dragons, a completely similar example of which is depicted in Mianrodan, but on the golden bowl from Kashan, so based on what has been described, this manuscript is Iranian and has the characteristics of Iranian art of Seljuk and Khwarazmshahi periods. The titles of the book are also written in Kufic script, which all researchers agree that it is Iranian. It is appropriate to attribute ir to Iran rather than to the Jazireh. It is necessary to remember that based on the available evidence, it has sometimes been seen that a copy has the artistic characteristics of one region but was illustrated for ruler another land. In such examples, the issue is not out of two situations, or that the copy in question was made outside the territory of the said ruler and was given to him or written on his order. There are many examples of this type. Like Ferdowsi’s Shahnameh, which was written in Tus and sent to Sultan Masoud’s court in Qazneh. Or, an artist migrated from one place to another and painted there, in which case he followed the style of his origin and his art shoud be attributed to his origin, to the place where the art is performed. Apart from all of these, the examples of paintings that are attributed to the Mousel or the Jazireh, were mostly influenced by the style of Baghdad, although the influence of Seljuk painting can also be seen in some of them, like the ways of drawing clothes, there are two ways of working in the paintings of this area, one is Baghdad style and the other is a combination of Baghdad style and Iranian painting. This method is mostly seen after the Mongol attack on Iran. In this method, some clothes are made in the style of Baghdad, which are pleated and shaded and others are drawn in the Iranian way. In Iranian paintings, the clothes are mostly simple or geometric and plant designs can be seen on them, however, in some examples the influence of Baghdad style pleated clothes can be seen. The faces are also influenced by Iranian art, but they are drawn a little more formally and seriously. As mentioned earlier, among the examples of mixed works illustrated in Mosul, we can mention the copy of Al-Aghani’s book, in which the clothes of the clothes of the courtiers are painted in the style of Iran. The expression of the faces is also influenced by Seljuk art, but it has differences from it, which can be clearly seen by comparing them with the Al-Tariaq version. Therefore, if this version was painted in Mosul or on the Jazireh, these clothes or a part of them should be pleated in the style of Baghdad, if such a thing is not visible in them. (Fig 28). But where was this version written and painted, finally, it can be said that it was during the Seljuk and Khwarazmshahi periods, according to the illustrations in the Al-Tariaq book and the examples compared with Iranian pottery and metal vessels. It is believed that this version was mostly likely painted by an artist in the Isfahan region, especially Kashan, less likely elsewhere in Iran. 

Abstract
The concentration of activities and sites Iron Age excavations carried out in Iran in the quarter-northwest Iran. It covers the west, northwest, north of the center, and the west bank of the Caspian Sea. The important point is that the chronological basis of the Iron Age in Iran is also based on the excavation of several sites in a small part of the northwest and its extension to the whole of Iran. Thus we see the Iron Age archaeological activities at the eastern part of Iran and especially North East is very unknown. Iran has long been the entry point for people without a nomadic component steppes of northeastern North Asia region is the Iranian plateau. According to written sources the oldest nations that have entered the Iranian plateau, known as the Indo-Iranian or Aryan tribes from the steppes of northern Asia to the south and in the land of the Pamir Mountains to Anatolia widely dispersed. Many scholars consider the gradual movement of these tribes to be from the second millennium. A period that is almost synonymous with the Iron Age in the region. But our knowledge of the Iron Age northeastern Iran today virtually all North Khorasan Province and the northern part of Khorasan Razavi province involved is negligible. This paper is based on the latest research picture of the Iron Age northeastern part of the country, with emphasis on the upper basin Atrak be provided. According to the study and identification carried out in this basin, the Iron Age of the upper Atrak basin is part of the Yaz 1 culture.
Keywords: Northeastern Iran, Iron age, Upper Atrak basin, Yaz 1 Culture, Archaic Dehistan, Settlement Patterns.

Introduction
It has been less than a decade that steps have been taken to understand the Iron Age in Northeastern Iran through surface explorations and excavations. Based on this, it seems that some parts of northeastern Iran are in the cultural area of Archaic Dehistan and another part is in the cultural area of Yaz I (Basafa 2017, Dana & Hejebri Nobari 2019, 2021, Vahdati 2016, 2018). The upper Atrak basin is an almost rectangular valley with a length of 90 km and an average width of 20 km. This region is one of the most important regions of northeastern Iran in terms of population movement because it connects the north of Kopet-Dagh to the interior regions of Iran and the center of the Iranian Plateau (Fig.2). Northeastern Iran has long been the place of entry of nomads from the northern steppes to the inner regions of the Iranian plateau. Due to the geological feature, Kopet-Dagh act as a barrier between the Karakum desert in the north and the fertile areas in the south, which cannot be crossed except through a few natural passages. 
More than 500 sites were identified in the archaeological surveys of the upper Atrak basin, among which 23 sites were dated to the Iron Age (Fig.3).

Iron Age Sites in the Upper Atrak Basin
The 23 Early Iron Age sites identified in the upper Atrak basin are listed in Table 1. In the surface survey of these sites, the only available data was pottery. In all Iron Age sites of this basin, the dominant pottery is Yaz 1 hand-made pottery. These pottery are poorly made, rough and in the range of buff and bright red, and the motifs are usually drawn geometrically with ocher and jujube red colors, and most of them are mixed with grog. 9 of the identified sites can generally be attributed to the Iron Age, and traces of Yaz I painted pottery were not found in the surface surveys. The pottery of these 9 sites are similar in form to the pottery of the Archaic Dehistan culture, but unlike them, they are in the buff and red spectrum.

Location based on ٍlevation Factor
The Iron Age sites of the region are located at an altitude between 1007 and 1718 meters above sea level. The size of the smallest site is 0.01 and the largest is 10 hectares. Examining the Pearson correlation coefficient regarding the area of the enclosures with the height factor shows -/299 (Table 2), which indicates a negative but moderate correlation. This means that as the height above sea level increases, it is expected that the size of the enclosures will decrease due to the limitations of natural factors.

Water Resource Factor
The distance of the Iron Age sites in the region from permanent water sources, including rivers and other running water sources, ranges from 0 to 6395 meters, and their average distance is 1441 meters. Pearson correlation coefficient/313. (Table 2) states that this figure shows the relationship between the direct and average level of significance between the size of the sites of the region with the factor of distance from permanent water sources. 

Land Use Factor
Pearson’s correlation coefficient between the size of the sites of the region with the soil type factor of the location of the sites shows -.054 (Table 2). This figure is weak and small. It is expected that there are large sites in the sedimentary plains and smaller sites on the edge of the plains and mountain slopes, and this is not the case in this area.

Slope Factor
Pearson’s correlation coefficient between the sizes of the sites of the region with the slope factor of the location of the areas is 0.72. (Table 2). The figure shows a very weak relationship between the size of the sites and the degree of slope of their location. 

Slope Direction Factor
Pearson’s correlation coefficient between the size of the sites of the area with the slope direction factor of the location of the areas shows -240 (Table 2). This phenomenon shows that some of these sites have not been used for a long time or that the different slope directions were not so important for the residents of this site in different seasons.

Communication Routes Factor
The sites of the region are located at a distance between 0 and 15355 meters from the main communication routes today. The Pearson correlation coefficient shows -114 (Table 2), this figure shows a very weak and small and inverse relationship. In other words, as we move away from the main communication routes, we should expect the size of the enclosures to decrease and become smaller.

Distribution of Iron Age sites in the Upper Atrak Basin
In this research, in order to obtain the distribution pattern of settlements in the region and to better analyze and understand the distribution of archaeological sites in the region and to find a pattern that fits environmental variables, the statistical method of cluster analysis has been used. Based on statistical analysis and their clustering, three patterns were obtained (Table 3, Chart 1).
Settlement distribution pattern 1: Settlement distribution pattern 1 includes 6 enclosures (Chart 1, Table 3). Due to the location of these types of sites in the landscape of the region and according to the distribution of these settlements on the level of the plain and the highlands, their small size, which is less than half a hectare, the economic method of these habitats can be assumed as temporary and seasonal settlements.
Settlement distribution pattern 2: There are 14 enclosures in this pattern (Chart 1). Due to the location of these types of sites in the landscape of the region and according to the distribution of these settlements on the level of the plains and the highlands, their small size, which is less than two hectares, the economic method of these habitats can be assumed as agricultural and livestock settlements.
Settlement distribution pattern 3: There is only one site in this group, and the reason for their placement in a cluster or separate pattern is its very large area compared to other sites. The size of this site is 2.2 hectares. The characteristics of this site, especially being located at a high altitude and a long distance from water sources and communication routes, and other characteristics show that it is similar to model 1, and only because of the difference in the size of this site, it is placed in a separate group.

Conclusion
The largest sites in the upper Atrak basin (except the IUA03 site) are located almost in a vertical line and very close to each other, Tappe Yam with 10 hectares, Tappe Ja’far Abad with 2.8 hectares and Sofalgaran-e Zadak site with 3 hectares, for a total of about 16 hectares from the total 33 hectares, half of the size of the Iron Age sites cover this basin. Today, these sites are located around the city of Faruj and almost in the middle of the plain. This area can be considered as the crossroads center of important roads in the region.
The important point in the reconstruction of the roads is the mountainous conditions of the region, which does not allow passage anywhere. With these conditions, there is only one possible way in the south, and that is today’s Binalud-Shah Jahan road, which goes from Quchan to Sabzevar. Near this road, there is Tappe Golshan Abad, which is actually located in the entrance area of this mountain pass. 
However, it is a little difficult to determine the northern route to pass Kopet Dagh and go to its north due to the number of valleys and the connection of some valleys with each other. By carefully examining the existing routes in the area and their connection with the Iron Age sites, a route is suggested that includes the sites of Tappe Yam, Dalan Tappe Kukach, Dalan Tappe Bozorg and Unnamed Tappe of Milanlu.
The western road along Atrak River connects the upper basin to the middle Atrak basin.
The eastern road also continues to the Kashaf River basin and the Mashhad plain without any natural obstacles.
Today almost all researchers agree that the people had Yaz I culture, nomads. Since Yaz I remains in a wide area of Greater Khorasan and the southern parts of Transoxiana, the route of population migration will inevitably pass-through Greater Khorasan through the north-south routes that connect the steppe regions of North Asia to its inner regions in the Iranian plateau. In this view, the upper Atrak basin is located in the area of Yaz I pottery culture, and due to its strategic location, it plays a very important role in the arrival of people with Yaz I culture to the inner parts of the Iranian plateau.

Abstract
Abstract: This essay attempts to do a typological study on one of the most applicable lighting devices -i.e. Oil Lamps- of the early Islamic period from Iran. Although introduction of Iranian ceramic Oil Lamps goes back to the pre Islamic period of Iran, the most remarkable changes in the design process of these products appeared during this period. Therefore, the main goal of this research is to study and follow design process of Iranian ceramic Oil Lamps of early Islamic period. This essay enquires about the most important developments on the history of Oil Lamps design. In order to reach the goal of this study and to do this research I have used descriptive analytical methodology of research and collected a great deal of needed information by desk study methods of data gathering. In addition, in order to delineate as good as possible the changes and developments appeared on various types of Iranian ceramic Oil Lamps from early Islamic period, here in this study I decided to use a specific framework for systematically studying history of objects’ design suggested by an Indian university professor named Kumar Vyas. According to Vyas, in order to be a major landmark a moment in the history of an object should indicate five kinds of changes: changes in design and structure of devices; changes in appearance of them; changes in methods of manufacturing; changes in the ways they have been used; and finally changes in objects’ relationship with their users. Therefore, one can categorize the most important developments in designs and types of Iranian ceramic Oil Lamps in three main groups. The first group includes those ceramic Oil Lamps with open, bowl shaped bodies and projected wick holders; Second group have globular enclosed bodies with elongated tubular wick holders. Finally, footed lamps with central stem on a plate shaped stand recognize the last group of our typology of Iranian ceramic Oil Lamps from early Islamic period.

Introduction
Oil Lamps or “chiraghs” were one of popular lighting devices of early Islamic period in Iran. They were kind of a container that simply worked with a vegetal wick and animal oil and thus answered their users’ needs. Although introduction and application of Iranian ceramic Oil Lamps goes back to the pre Islamic and especially the early historic period of Iran, but because of the development and improvement of related technologies of pottery in the Islamic period, the most remarkable changes in the design process of these products appeared during this period. It goes without saying that both design and production of ceramic devices were mostly relied on the advanced technology. During early Islamic period, it seems that Iranian has used pre-Islamic and specially Sasanid forms. However, gradually there has occurred considerable progresses in making and decorating potteries, promoting mostly their visual and aesthetic effects along with enhancing their quality of production. While ceramic Oil Lamps were among most popular lighting devices of early Islamic period in Iran, after Mongol invasion in the early thirteenth century their application has been reduced and ceased. 
The main goal of this research is to study and follow design process of Iranian ceramic Oil Lamps of early Islamic period. The question I am going to answer here is how the design of mentioned devices has changed during time and under what conditions. Here, studying the most important developments and changes in design styles of Iranian ceramic Oil Lamps from early Islamic period, I tend to trace and delineate the evolution path passed through by these devices from the beginning of the Islamic period until the end of 12th / 6th century. 
Materials And Method: In order to reach the goal of this study, after reviewing related literature and explaining specific methodology of research, first I have discussed the terminology of Oil Lamps in Persian and tried to describe its function. Then in two parts, I have structured my discussions. In the first part of the body, I have divided forms of ceramic Oil Lamps of Islamic period into three main groups. Then, in the next part, I have tried to explain the major distinctions between these groups by Kumar Vyas’s criteria. These are changes in design and structure of devices; changes in appearance of them; changes in methods of manufacturing; changes in the ways they have been used; and finally changes in objects’ relationship with their users. 

Data
Collecting data for this study has been conducted by desk studies, including materials from books and websites. These data, here, has been analyzed qualitatively.
Data collection techniques refer to methods used to collect and analyze different forms of data. Collecting data for this study has been conducted by desk studies, including materials from books and websites. These data, here, has been analyzed qualitatively. In this study, data are made up of material evidences of ceramic oil lamps from early and middle Islamic periods. These evidences are accessible sometimes directly through museums and collection of Islamic or Persian art all over the world and sometimes indirectly through reproduction of those materials within catalogues of Islamic ceramics available in libraries. First of all it was very important to distinguish between oil lamps and other kind of lamps prevalent in Iranian art of Islamic period. Then one should consider historical order of lamps so it could be possible arranging them into two groups of early and middle Islamic period. Whitin each category, there exist many forms of lamps with multiple ways of decorating them including monochrome glaze or underglaze decorations. Then the researcher has to sort these evidences by their historical period, first, and by their forms and shapes, second. Furthermore they should consider their decoration in order to reach a better understanding of them. In order to delineate as good as possible the changes and developments appeared on various types of Iranian ceramic oil lamps from early Islamic period, here in this study I decided to use a specific framework for systematically studying history of objects’ design suggested by an Indian university professor named Kumar Vyas. According to Vyas, in order to be a major landmark a moment in the history of an object should indicate five kinds of changes: changes in design and structure of devices; changes in appearance of them; changes in methods of manufacturing; changes in the ways they have been used; and finally changes in objects’ relationship with their users.

Discussion
One can categorize the most important developments in designs and types of Iranian ceramic Oil Lamps in the early Islamic period in three main groups. The first group includes those ceramic Oil Lamps with open, bowl shaped bodies and projected wick holders. In these lamps, reservoir and wick holder are closely connected to each other. Second group of Iranian ceramic Oil Lamps from early Islamic period have globular enclosed bodies with elongated tubular wick holders. Here, wick holders earn distinctive characteristic of its own and it somehow separate formally from reservoir. Finally, footed lamps with central stem on a plate shaped stand recognize the last group of our typology of Iranian ceramic Oil Lamps from early Islamic period. The form of main part in lamps of this group is not so different from that of first group. However, having been elevated by a tall cylindrical column has made the function of lamps of this group much more distinctive than those of other groups. 
Drawing upon Kumar Vyas’ approach to systematically studying history of objects’ design, one can analyze the main distinctive aspects of these three types of Iranian ceramic Oil Lamps from five point of view: changes in design and structure of devices; changes in appearance of them; changes in methods of manufacturing; changes in the ways they have been used; and finally changes in objects’ relationship with their users. Design and structure of Oil Lamps from these groups are more remarkable that changes in other aspects. However, the most important development during the history of these Oil Lamps is their way they have been seen and thus used by their owners. Certainly, Simple forms of lamps from first group did not need as complicated treatment as it was necessary dealing with lamps of third group. 

Conclusion
Iranian ceramic Oil Lamps in the early Islamic period can be categorized in three main groups. The first group includes those ceramic Oil Lamps with open, bowl shaped bodies and projected wick holders; Second group of Iranian ceramic Oil Lamps from early Islamic period have globular enclosed bodies with elongated tubular wick holders. Finally, footed lamps with central stem on a plate shaped stand recognize the last group of our typology of Iranian ceramic Oil Lamps from early Islamic period. Here, in this essay, distinctive aspects of these groups have been analyzed from five point of view, according to Kumar Vyas’ approach to history of objects design. Design and structure of these three types are distinctive in their form of body and wick holder. Using different kinds of glazes and painting techniques has made the appearances of Oil Lamps somehow unique. Ceramic Oil Lamps of these groups also have been produced by various processes. Furthermore, the way they have been used varied form lamps of one group to the other. Finally, mention has to be made of the relationship between users with every lamps of each group. Based on design and appearance of lamps this relationship has proven to be remarkably discrete.   

Abstract
In recent decades, cultural heritage-related concepts have been widely investigated, and agricultural heritage has been adopted as a concept of cultural heritage because of its contribution to livelihoods, food security, and the world economy. This consideration from 2002 to 2018 led the Food and Agriculture Organization (FAO) to develop a framework known as Globally Important Agricultural Heritage Systems (GIAHS) and to introduce global agricultural heritage sites accordingly. The GIAHS committee presented five criteria for incorporating the sites in the list of globally important agricultural heritage. Biodiversity, local awareness and techniques, socio-cultural values, food and livelihood security, and visual landscape were included in the five categories; thus, this article aims to evaluate historic farmsteads in the central Iranian regions. Historic farmsteads were thought-about an efficient agricultural production system characterized by architectural, economic, social, and cultural features in the past, the traces of which are still available. The main research subject concerns the growing destruction of farms following climate changes, the migration of owners and beneficiaries, and the lack of community knowledge about their nature. The research main goal is to introduce Iranian historical farmsteads as a globally vital agricultural heritage system. Thus, the research seeks to investigate the issue through an interpretive approach and an interpretive strategy and to use field studies and document research to respond to research questions on Iranian historical farmsteads in conjunction with global agricultural systems. This research concludes that the potentials of historical farmsteads meet GIAHS standards. The GIAHS secretariat can also identify the Iranian historic farmsteads in the first stride and then register them internationally. It will help many historical farmsteads as a large part of the Iranian agricultural heritage to be dynamically conserved.

Introduction
In recent centuries, traditional agricultural activities have decreased, considering numerous reasons, along with the rapid development of cities (Oosterveer & Sonnenfeld, 2011). In the meantime, preserving cultural heritage for a sustainable livelihood has received much attention as many studies on sustainable development have focused on people, the environment, and cultural heritage (Ojomo, 2010). As a result, a new concept known as agricultural heritage was added to cultural heritage. Then, in 2002, the conception of globally important agricultural heritage systems (GIAHS) was developed by the Food and Agriculture Organization (FAO) in the international arena. The first global GIAHS summit was held in 2018 after 16 years (Behzadnasab, 2019:9). GIAHS was introduced to the world not as a specific product or geographic area but as a recognized system. The National Committee of GIAHS was established in 2014 in the Iranian Ministry of Agriculture Jihad called NIAHS, investigating issues such as the irrigation of aqueducts and migration of nomadic Qashqai tribes (Joafshan-Vishkaea, 2015:18). Each GIAHS site should have a historical and contemporary aspect and can be restored and developed to the benefit of future human generations. 
Therefore, many sites with agricultural heritage potentialities in Iran can be regarded as possible candidates in the future. This article aims to focus on “historic farmsteads of central Iran” as a proposal for inclusion in the GIAHS list to evaluate them according to the five criteria mentioned above. In the central regions of Iran, especially Qom, Kashan, Niasar, Semnan, Isfahan, Meibod and Yazd, these farmsteads have two physical and functional characteristics, but some criteria for their implementation have already been established (Raie, 2017:230). Historic farmsteads were efficient agricultural production systems of the past with architectural, economic, social and cultural features, the remains of which can still be seen today. Presently the main problem is the non-recognition of such historic farmsteads as globally recognized agricultural heritage. They are considered to be threatened by various factors, such as climate change and migration by landlords and beneficiaries. The research aims to introduce these farmsteads as a globally important agricultural heritage system. Thus, the research seeks to investigate the issue through an interpretive approach and an interpretive strategy and to use field studies and document research to respond to research questions on Iranian historical farmsteads in conjunction with global agricultural systems. 

Data
Farmsteads in the past had two functional and physical systems. These systems, which are based on lived knowledge and techniques, are experience-oriented and traditional and have caused the formation and consistency of farmsteads from the past to the present. Much data related to traditional knowledge about architecture, agriculture, civil, economic, legal, cultural, social, and political fields can be introduced and revived in the heart of Iran’s historical farmsteads.

A) Physical system
1. Order of position and formation including; Methods of choosing the location of farmsteads with two priorities of water and security (Raie, 2020: 59);

Discussion
The FAO provided five criteria for identifying agricultural heritage systems worldwide; biodiversity, traditional knowledge and technology, socio-cultural values, food and livelihood security, and visual landscape. This research investigates the locality of Iranian historical farmsteads in conjunction with agriculture heritage criteria. Regarding the first criterion, there is a significant relationship between historical farmsteads and agro-biodiversity. The presence of water in different regions diversifies agricultural products, livestock and poultry.
Planting of damask rose and the production of rosewater in Niasar farmstead, as well as straw oil extraction in Nahchir farmstead in Isfahan, can be cited as good examples in this regard. Concerning the criterion of local knowledge, the farmsteads are said to be based on living experiences and old knowledge. These problems are recognized in terms of two physical and functional characteristics. The third criterion deals with cultural values and social entities at the farmsteads. Fixed population rates and the presence of a group of beneficiaries and stakeholders suggest that farmsteads have achieved sustainability with the collaboration of these groups of people over time. The fourth criterion concerns food and livelihood security. Historical farmsteads have, at various periods, been regarded as economic and production businesses for people, landlords and the government, making significant contributions to the agro-tourism sector. The fifth criterion evaluates the farmsteads’ landscapes. The population, physical environment, and agricultural lands can all be used, to illustrate the natural, cultural, and historical landscapes of central Iranian regions. Landscapes are presented on both an internal and external scale.

Conclusion
The study concludes that the historical farmsteads in Iran significantly met the five criteria after carefully examining them. In addition to their historical significance, historic farmsteads continue to exist today and contribute to food and agricultural security in various places. They have gradually adapted to their surroundings, producing assorted products based on cultural and economic values while retaining and increasing agro-production knowledge and practices.
Local residents and stakeholders have worked together in this regard throughout time to maintain the farmsteads. Farmsteads have been a product of continuous human presence in the environment, creating cultural, historical, agricultural, and visual landscapes. The GIAHS secretariat can first identify historic farms in the central regions of Iran and then have them registered globally using executive guidelines. It makes it possible to study a variety of vital and previously disregarded farm data, leading to their dynamic conservation based on location and time needs.

Abstract
So far, the settlements of the Iron Age of Sarakhs plain have not been studied archaeologically, and on the other hand, the Iron Age of Plain Sarakhs represents the Yaz culture in the region and owes its name to the Yaz Hill area in southwestern Turkmenistan. Studies of the Iron Age culture of the Sarakhs Plain can reveal the basic information of this period and help to understand the general Iron Age of the Iranian plateau and the land of Turkmenistan. The purpose of this study, while identifying Iron Age settlements, is to analyze environmental factors to explain the patterns of Iron Age settlements in the Sarakhs plain. For this purpose, a field study was conducted in the plain and by studying the collected works and library studies. It was found that 16 sites have Iron Age artifacts. Some settlements are single-period and some have chronological sequences. The necessity of the present study is the unknown culture of the Iron Age of Sarakhs plain. Therefore, the identified Iron Age settlements of Sarakhs plain were analyzed from the perspective of environmental factors and their role in explaining settlement patterns. The output of maps and data of Iron Age settlements in Sarakhs plain showed that among the environmental factors influencing the determination of settlement patterns, Distance and proximity in the range of 300 to 900 meters above sea level, Location of settlements along the rivers of Sarakhs plain (linear settlement pattern) and large urban or rural centers (Mir Ahmad and Bazangan) up to 65 hectares (central location), Communication routes (communication route of Greater Khorasan in the Iron Age), In the formation and distribution of settlements have been more influential than other environmental factors. One of the most important results of the present archaeological study, Identifying the Iron Age settlements represents the culture of Yazd Plain Sarakhs, which will be used to measure the distribution of Iron Age settlements in this area to draw a very accurate and comprehensive perspective for understanding the social life of the people of that period.

Introduction
Sarakhs Plain as the research site has been a favorable habitat for the formation of various human communities due to its natural potential and optimal environmental conditions, including altitude, suitable soil and relatively favorable weather conditions. The study of the collected works of the Iron Age in the Sarakhs plain through archaeological investigation shows that some cultural traditions of southwestern Turkmenistan (Yaz culture) of the Iron Age were prevalent in the Sarakhs plain, and this plain is probably the link between the southwest of Turkmenistan and the northeast of Iran and culture. Its pottery is noticeably and significantly influenced by the culture of southwestern Turkmenistan (Yaz area). At the end of the Bronze Age, a new culture covers Central Asia and Southwest Turkmenistan, which is known as the Yaz culture, and it borrows its name from the Yaz Tepe area, located in the southwest of Turkmenistan and present-day Ashgabat. The pottery of this period is generally simple and in red, pea and gray colors.

Materials and Methods
The current research is based on the purpose of fundamental research and based on the nature and method of descriptive and analytical research. The method and tools of data collection in this research have been done in two ways: documentation and field activities. In the field survey, while surveying the plain in the region and identifying the settlements, the required archaeological information and evidence (pottery) were collected from the said sites and recorded in the database. In order to obtain scientific answers, the conventional methods of establishment patterns and GIS and Spss analyzes were used in this research, and after preparing the outputs and maps, two descriptive and inferential methods were used to analyze the questions.

Data
Our information about the land of Turkmenistan is based on the findings of Russian and Turkmen archaeologists’ excavations in the region and presenting their latest findings and reports, some of which have been translated and used, which can be used as library studies. he remembered at this stage, all written sources, images and maps were collected and analyzed. In the field investigation, while surveying the plain in the region and identifying the settlements, the required archaeological information and evidence (pottery) were collected from the mentioned areas and recorded in the database.

Discussion
At the end of the Bronze Age, a new culture covers Central Asia and Southwest Turkmenistan, which is known as the Yaz culture, and it borrows its name from the Yaz Tepe area, located in the southwest of Turkmenistan and present-day Ashgabat. The iron settlement patterns of the Ferns Plain have been formed with the influence of these environmental and natural factors. With these interpretations and based on this, in the current research, the relationship of each establishment and establishment patterns with respect to major and main environmental variables have been analyzed and measured.

Conclusion
During one season of archeology field investigation in Sarakhs Plain and study of collected works and library studies, it was obtained that the extent and continuity of culture in the place, the proximity and location of the settlements along the Tajan, Harirood, Kashafrood, Shurluq and Chakoodar (linear settlement model) in all the geographical directions studied in Sarakhs Plain showed that This plain has a direct relationship with the facilities and environmental conditions, such as the quantity and quality of settlements, the frequency and increase of the Iron Age settlements of the Sarakhs Plain compared to the previous period in terms of population density and the gradual complexity of the relationships between settlements and the relationship with the environment and Direct exploitation of water resources for agriculture and animal husbandry has been on the rise and in the last period of the Iron Age It increased all of a sudden and it is through this plain that this culture spread to other areas of South Khorasan and the plateau of Iran. In order to analyze and explain the settlement patterns of the Iron Age of Sarakhs Plain, a test was conducted between various ecological variables with the distribution of settlements based on the Pearson correlation coefficient and the effect of the significant level. The result of this study was the identification of 16 settlements from the Iron Age, which can be considered and evaluated from the perspective of environmental factors and the size of the sites. In the analysis and explanation of the Iron Age settlements in the Sarakhs Plain, the height above the surface of open water, the distance from rivers and other water sources, and the distance from communication routes with Pearson’s correlation coefficient with a significant level, had the greatest impact, and the other variables each implied They have left a significant impact on the Iron Age settlements of the Ferns plain. The results of Pearson’s correlation coefficient indicate that the distribution of Iron Age settlements in the Sarakhs Plain are regularized in relation to environmental and ecological capabilities and limitations, and these factors have played a significant role in the spatial distribution, determining the type of function and the importance of Iron Age settlements in the Sarakhs Plain. This has had an undeniable effect on the distribution of the population, the type of livelihood, the settlement patterns and their bodies. The Iron Age settlements that can be seen in this plain are the result of the specific geographical conditions of the region.
