Abstract
Migrant Scythian tribes were occupied many parts of the Eurasia following a move to the West in the first millennium B.C. The Scythian people were among the last Aryan tribes who, after the migration of other indo-European tribes, emerged from their mainland (Southern Russia) at the end of the Eighth century, and dispersed in Northern Central and Southern Siberia, the North of the Caspian Sea and its Western boundary, in the vast plains of the Caucasus Mountains. The purpose of this study is to investigate the influence area and cultural interactions of these ethnic groups in sixteen geographical zones of the Eurasia, from east to West. The present study in a historical method, with a qualitative approach and based on archaeological reports have studied dispersion of the Scythian type artifacts in the West Mongolia, Tuva region, the Altai region, Central Asia, Iran, South Caucasus, North Caucasus, Mesopotamia, Asia Minor, Crimea, southern Ukraine and South-East Europe, Egypt, Greece, West Mediterranean, Central and Western Europe. Because of the extent of the study area, in this research has been tried to be mentioned to the main of the Scythian areas in the each zone and its materials, so that be shown a detailed view of the extent of this culture in Eurasia. The present research has been carried out according to these main questions: How is the extent area of the Scythian culture? What is the type of their materials in each of these areas? The results point to the vastness of this culture in a wide area of geography. The culture has been able to influence many cultural and geographical areas and attract the cultures of many tribes, in the short time. In many of the areas studied, there are similar findings from this culture.

Intrudoction
When a tribe enter to an alien land as an immigrant or an invader, it develops its culture as an effective factor over time. Although immigrant or invading peoples may not pursue such a goal, undeniable impacts and cultural relations, as a factor in stimulating such processes, will accelerate. They seek to dominate human resources in the every part of the world, and change the cultural, political, and social equations of the conquered regions and, after consolidating their presence, propagate purposely their culture. In the meantime, due to cultural interactions, the art of these immigrant or invading generations also affects. This impact has been associated with war in most cases, and the outcome of such a struggle is the creation of a cohesive culture in a wide range. The more these wars continue and wider, the greater the culture of dominant folk; in this process, the power of the invading force is a major factor. The generators of homogeneity in this area act in the most common and similar cases. In other words, the cultural attributes of a people in two distant geographic districts show similar characteristics. The development of the culture of the Scychian peoples in a widespread zone, and in a short time, has almost followed such a mechanism. Scythian people at the beginning of the first millennium B.C in their movement were to the west, Central Asia, North and South Caucasus, the north of the Black Sea, East Europe, Northwest of Iran, East Anatolia, Mesopotamia and the vicinity of Egypt and the Mediterranean Sea and they left their cultural features in these areas. In these movement they, they left many traces such as unique burials, special techniques for decorating ornamental objects. The course of the movement and how they deal with the ruling powers in these regions, including Urartu, Med, Mana and Asshur, in historical sources have been described.

Discussion
Basically, what is attributed to the Scythian people, is specific cultural material that specific to them. In terms of burial data, the horse has been a special place in the sacred burial ground, so that this can be seen in most of the ancient Scythian sites. In terms of burial data, the existence of objects such as triangular and flat iron and bronze arrowheads (often with a reverse barb) interesting cheekpieces with three holes in the middle of them for passage of rope that in most cases they end up with animals such as horses, eagles and rams, iron and bronze bits for harness, special styles for decorating objects (that known as animal styles, stickers and Other war material specifically) are show the art and culture of the Scythian peoples in Eurasia. The materials of the Scythian tripes have been found in the west of Mongolia from Beiram Kurgan: In Tuva region from Aimyrlig, Arglykty and Shurmak-Tei Kurgans; in Altai zone from Pazirik, Ust-Kuyum, Kurtu II and Katanda Kurgans; in central Asia the Scythian material have been found from Tasmola, Chilikta valley, Irtysh, Alakul, Uigarak and Tagisken Kurgans. in Iran have been found from Khoram Abad cemetery, in the south of Caucasus from Kar Mirblur, Musa Yeri, Chitan Dagh, in the north of Caucasus from Kelermess, Kostromaskaya, Ulski, Voronezhskaya, Ust-Labinskaya and Elizavetovskaya, in Mesopotamia from Assur, Musel, Karkmish and Al Mina. Also, the materials of the Scythian tripes have been in Asia Minor from Alaja Huyuk, Kernes dagh, Pazarli, Yazili Kaya, Gurdion and Hesarlik, in Krimeh from Temir-Gora, Perekop Isthmus, Talayevskii, Bosporus, Zolotoi, in the south of Ukrain and southeast of Europ from Elizavetinskaya, Chertomlyk, Solokha, Melitopol and Gaimanova mogila Kurgans, in Egypt from Tel Defaneh, Nakratis, Elfantin, Teps, in Greece from Aten, Atika, Delfi and Missen, in central Europ from Zwolaki, Zakrzow, Chelm, Morawy, Miyniec and Villach sites, in the west of Mediterranean from Megara Hibela, Katania and Motye sites and in the west of Europ from Brussels and France.

Conclosion
The remarkable expansion of the culture of the Scythian peoples over a wide geographical range during the few hundred years has made it one of the rarest ancient cultures. These nomadic peoples (wherever they could) have been left their cultural influence. In the areas where they entered, the most important work of their ancestors, the magnificent burials, is reminiscent, and in other areas, under their influence, the Scythian culture in the artistic objects of manifestation has been transported from the land to another country. So, the extent of damage to the their culture have been in east area Mongolia, in west with France in Europe, in north with Russia, and the southernmost part in Shush and Marvdasht.

Abstract
Among the ancient motifs from Iran and Mesopotamia, some pictures showing special shaped beakers can be seen but unfortunately no explicit comment has been made on the nature and function of these forms by researchers. Recently, 7 pottery beakers have been found in a Mannaean cemetery (Mala Mcha) and and Iron Age grave (Kani Koter) in northwestern Iran and authors are believed that their shape and possible function are compatible with some of these ancient motifs dating back from the third millennium B.C. to the Achaemenid period. A glazed beaker from Tepe Hasanlu which belongs to Iron Age II also has the same characteristics as the Mala Mcha and Kani Koter examples. Considering the symbolic meaning of the Lotus flower in ancient cultures, as well as their form and decoration, it seems that the Mala Mcha, Kani Koter and Hasanlu pottery beakers have a special application. Previously some researchers in some cases have interpreted these motifs as a Barsom (Barsam) or flower (often lotus). The authors propose that these objects that can be seen on ancient reliefs or ivories are simple or painted beakers equivalent to the clay beakers unearthed in these sites. Probably this type of beaker was not used as normal container, but it seems to have been utilized by high-level people during special events and banquets perhaps for drinking prized liquids. In addition, it seems that the samples of the Mala Mcha, Kani Koter and Hasanlu in terms of shape and possible there function, are comparable with some of the patterns of the motifs discussed in this paper. The grave of Kani Koter is rich and belonged to a warrior of high status. Also the graves of Mala Mcha which had pottery beakers were richer than other graves, and it seems that the users of them have superior position over others. The glazed beaker of Hasanlu was as well as obtained from a room with local and Mesopotamian specimens in a special room. In ancient motifs, users of these objects have a superior social position than others. In this paper, in addition to comparing the shape of the beakers of Mala Mcha, Kani Koter and Hasanlu with the remaining ancient motifs, Chromatography experiments were carried out which unfortunately, did not receive any laboratory data on its application.

Introduction
Archaeological excavation in 2012 at the Mala Mcha Cemetery near the ancient Mannaean site of Ziwiye in Kurdistan province, a number of very interesting pottery beakers were found which, according to the authors, seems to be the objects depicted in the images of ancient motifs from the third millennium BC until the Achaemenid era in the Middle East and Iran. Examples of these motifs are presented in the papers.
From Mala Mcha cemetery, five pottery beakers were found with a narrow body, and a large mouth that three beakers were identified from grave No. 5. Another two beakers is excavated from grave No. 7. The graves of 5 and 7, those containing these beakers are richer than others. The special shape of these beakers shows that they have probably had a special function. The painted beakers have a petal shape similar to lotus flowers. These potteries are often have a fine temper, well-fired, burnished, wheel-made and are comparable with Ziwiye potteries. The Garve of Kani Koter is located in the near of Mala Mcha and its tomb was destroyed by illegal excavator. The burial goods of it is rescued by Cultural Heritage of Kurdistan province. In Kani Koter grave 2 blue glazed beaker obtained which resemble to plain beakers of Mala Mcha. Different objects were obtained from this grave that indicating its richness that its artifacts is dated to Iron Age III.
In addition to these pottery beakers, a glazed pottery from the Burned Building II of Hasanlu (Iron Age II) also has a form and decorations that are almost identical to the pottery beakers of Mala Mcha and Kani Koter. In addition to these beakers, a number of glazed terracotta jars are also identified in the same layer that depicted them in Assyrian reliefs. Hasanlu’s sample is also one of the few glazed pottery that is of high quality and obtained with ivory and special objects, and it is believed that these objects are derived from the cultic context of Burned Building II of Hasanlu. The shape, motifs and the place of Hasanlu’s glazed beaker are indicative of its importance. The Excavator of Hasanlu believes that this beaker is made in the Solduz region, although it’s very similarity with objects from neighboring areas. 
It should be noted that the similarity between the burial goods of the Mala Mcha’s finds with the Mesopotamia and Iran is not limited to beakers and visible in other objects. A number of Mala Mcha vessels are similar to the Pasargadae and Assyrians potteries and artifacts of Kani Koter is resemble to Urartian, Assyrian and Mannaean samples. In Hasanlu’s excavation, various objects have been compared with the images of neighboring areas, and in particular the Assyrian. 

Ancient Motifs and Interdisciplinary Test 
In the ancient motif of the Mesopotamia and Iran sometimes a picture of a particular object is seen that used by some high-ranking people or gods, which has so far not been accurately detected about its nature and application. This object, often with a narrow body and a wide mouth, has a length of at least one beaker which according to the authors of this article can be a picture of a beaker. This image (beaker) is seen from the third millennium BC to the middle of the first millennium BC but in the first millennium BC is more. In this paper some ancient motifs with resemble picture like a seal impression from Tell Asmar that belong to third millennium BC, an ivory from Nimrud (1000-850 BC), Assyrian wall relief from Tiglath-Pilesar III from Nimrud have been compared. Among the palace reliefs of the Assyrian period; Sargon II (722-705 BC), there are similar motifs. In this motif, there is a banquet subject that is used this beakers, although its beaker is not exactly the same with the samples obtained from western Iranian excavations. Similar discussed beaker is seen in the Esarhaddon stone stele from Zanjirli. Some of the images in the following periods like Persepolis’s plain beakers which is seen in the hands of elite Persian and Median nobles on the East and north side of the Apadana is resemble to pottery beakers. These images are also presented as flowers. The similar picture is also seen in the rock-cut tombs of Qizqapan. To understand the function and the type of material used in the beakers of Mala Mcha, a chromatographic test was performed on them, which unfortunately did not produce the data that indicated their use. 

Conclusion
In some ancient motifs in the Mesopotamia and Iran from the third millennium BC to the Achaemenid period, a picture of a beaker-like object is seen in the hands of the gods and high-ranking people. These objects are depicted in important places or on important objects such as ivory. According to the authors, the similarity of the five pottery beakers from Mala Mcha graveyard and tow similar beakers form the tomb of Kani Koter, as well as a sample of beaker from Tepe Hasanlu IV could be considered as suitable samples for the type of function of these vessels. The motifs are also reminiscent of the role of the Lotus flower, a symbolic flower in the Middle East. The use of painted beakers that is the same can be seen reminder of Lotus flowers.

Abstract
During the fourth millennium BCE similar wares used to produce and use in the extended area in Near East which is so-called Beveled rim bowls. Its importance is for high quantity and similarity in production techniques. Different studies on dating, function, and the main reason for the spread of this pottery style have been done. Although beveled rim bowls were found in many sites in west, south, south-eastern, and central plateau, hereby new finding from Kale Kub seems that this pottery style was spread in the more extended area than what we expect. Kale Kub is located in the eastern part of Iran, Southern Khorasan, and Sarayan county. In 2018, two trenches were opened in order to identify the stratigraphy of the high amount of beveled rim bowls in addition to other pottery styles belong to fourth millennium BCE which are already known in southwestern Iran. The current study would be clarifying the importance of the Kale Kub site for identifying the dispersal zone of Beveled rim bowl pottery style by an endeavor firstly foe the classification and typology of the potteries and then a comparison between the pottery style in this site with other sites related to this period. Also, we attempt to trace the possible routes for this pottery style to the East and the interaction between east and west of Iran. Pottery collection from the excavation in Kale Kub includes a high amount of beveled rim bowls, Banesh tray, and some other pottery styles which are well-known from fourth millennium BCE such as nose handle and spouted wares. Beveled rim bowls are over 15 percent of the pottery collection and other styles have a few quantities in the collection. In term of production techniques and style, Kale Kub finds are similar to those from southwest of Iran.
Keywords: Eastern Iran, Kaleh Kub II, Beveled Rim Bowls, Forth Millennium BCE.

Introduction
The first season of excavation at Kale Kub aimed to identify the stratigraphy sequence of this site, which has revealed the chronological sequence from fifth to late fourth millennium BCE. Cultivation and human activities in recent years resulted in disturbance in most parts of the site. Beveled rim bowls, Banesh tray, and other diagnostic pottery styles of fourth millennium BCE are the most important finds in this site. In addition to beveled rim bowls and Banesh tray, other diagnostic styles such as nose handle, spouted wares were found in Kale Kub that shows all styles belong to this millennium would have seen in the eastern part of the Iranian plateau. In modern Iran, these pottery styles are reported from the southwest, central Zagros, central plateau, and southeast, but from east and northeast just reported from Farhad Gerd which scholars believe that the reported pottery is not beveled rim bowl. Excavation in Kale Kub shows the extension of this culture to the east part of Iran. This site is located far from the well-known sites from this period in the west part of Iran and there are two deserts, Dasht-e Kavir and Lut desert, between this site and other known sites with similar pottery style increase the importance of finding the answer for this question that how this culture found its way to the east.

Conclusion
Inter-regional interactions had a significant effect on the movement of raw material and production in the extended area. Because of the geographical situation of Kale Kub at the east of Iran and the existence of metal mine in the region, this site possibly appeared as a supplier place in the interaction networks for the southwest of Iran during the fourth millennium BCE. The pottery culture which is prevalent in the southwest in this site shows clearly these interactions. To answer the question of how they were connected, we need more excavations and more information. The nearest sites with similar cultural features to the Kale Kub are Tepe Sofalin in Pishva, Varamin in central plateau; and in the southeast of Iran, Mahtout Abad in Jiroft, that both have about thousand kilometers are away from Kale Kub. This distance shows that there are highly probable some other sites between Sofalin and Kale Kub and also Mahtout Abad and Kale Kub that have not been identified yet. These two-direction routes (first, the southern boundary of Alborz mountain and north of Dasht-e Kavir; second, the southern part of Lut desert to the Sistan region and eastern parts of Iran), are the possible routes that connect the east to the fourth millennium BCE cultures of southwest in purpose of achieving the raw material. In the highlands around Kale Kub, copper mining evidence showing that these mines were used till late Islamic periods in the region as well. Also, this region has various types of opal. Kale Kub location between Afghanistan and inner part of Iranian plateau suggests that this site was formed on the way of lapis-lazuli movement routs from Afghanistan; also, the mines of turquoise at the Neishabur is near to the site. Although, finding the role of this site in the networks of fourth millennium BCE needs more information that will be revealed by more excavations but current evidence shows that this site had an exchange and production function in the trade in this period. It suggests that beveled rim bowls and other material culture from fourth millennium BCE (about 3600-3500 BCE) extended to the east from the central plateau and southern part of Alborz Mountain as well as northern side of Dasht-e Kavir.

Abstract
Archaeological studies on the northern coasts of the Persian Gulf are in the early stages. Although such studies have been started in this area for decades, long interruptions have led to a lack of reliable results. This issue is more acute in the prehistoric period. Limited research results publication has also increased this problem. Although archeological surveys have been done well in Bushehr province, unfortunately, the results of those studies have not been published well. Studying on the northern coasts of the Persian Gulf is not just a research topic today; it is a research duty. Archaeological studies conducted in this region have shown that at least from seven thousand years ago, people who live on the land of Iran have been settled on the northern coasts of the Persian Gulf and had the opportunity to use the sea; although in the early periods this settlement was seasonal; but according to the new evidence of mud-brick architecture at Toll-e Suzo, villages and then permanent cities have been created in this region since the fourth millennium BC, and in the historical and Islamic period, these areas have been completely inhibited. In addition to the food supply, the sea has been playing an important role in trade relations since the Fifth/ fourth millennium BC, which should be considered in archaeological studies of the region. Toll-e Suzo, which is located in Genaveh district, Bushehr Province, is one of the prehistoric sites of the region, which, according to the cultural evidence identified from the excavation in the stratigraphic trench, has been settled from the middle of the fifth millennium to the end of the fourth millennium BC. The inhabitants of this area have been in contact with the interior of the Fars cultural region and southwestern Iran and have also access to marine resources.
Keywords: Persian Gulf, Archaeological Excavation, Toll-e Suzo, Middle Bakun Period, Lapuei Period.

Introduction
The first season of archeological excavations in Toll-e Suzo led to the identification of the cultures of the fifth millennium (Middle Bakun) and fourth millennium (Lapuei) BC, 28 km north of the Persian Gulf coast. This season’s excavation goal was determining the buffer and Core zoom of the site and stratigraphical excavation, which was carried out in the winter of 2017. In this excavation, a trench measuring 4 × 4 meters in the center and at the top of the site was excavated. The thickness of the cultural layers that have been excavated in this trench is 5.80 meters. During the excavation of this trench, two cultural periods with possible gaps were identified. It should be noted that 1.5 meters of the surface layers of the top of the site have been destroyed by bulldozers and surface layers/ periods are not excited. The lower layers (contexts 1016-1036) represent the Middle Bakun (late and mid fifth millennium BC) with diagnostic painted pottery from this period. This pottery is quite comparable with the findings of archaeological excavations in the Fars cultural region. Although the dimensions of excavation were small during this period, the establishment of this period in Toll-e Suzo can be considered as belonging to semi-monogamous communities that, according to the climatic conditions, were established in this area in suitable seasons. The Middle Bakun period is the culmination of several thousand years of pre-historical cultural development in the Fars region.
Research Methods: Archaeological field activity and library have been used in this research. In this way, during one season of field excavation, cultural evidence and archaeological documents were collected, and then by studying published references and library sources and archival reports, the background research of the region was studied and comparative examples were collected.
Research Questions: 1- The oldest settlement evidence of Toll-e Suzo is related to what periods? 2- What is the chorological sequence of Toll-e Suzo? 3- Is there evidence of Fars prehistoric cultures on the northern coast of the Persian Gulf? 4- Did the people of Toll-e Suzo have the possibility to exploit the marine resources?
Research Hypothesis: 1- The oldest cultural evidence of settlement in Toll-e Suzo dates back to the fifth millennium BC. 2- Toll-e Suzo has been identified according to the material evidence and the thickness of the settlement layers has two cultural periods; Bakun and Lepoi. 3- Fars prehistoric cultures were completely prevalent on the northern coast of the Persian Gulf in Bushehr province. 4- The animal bone evidence of the Toll-e Suzo excavations shows that the inhabitants of this area used marine resources.

Conclusion
During this period, despite regional differences, a large part of southern Iran reached uniformity in terms of material culture (Week et al, 2010). Regarding the distribution of Bakun pottery in such a wide area from the Persian Gulf in the south to the Bakhtiari Mountains in the north and from the eastern borders of Khuzestan in the west to the western borders of Kerman in the east, the hypothesis of traveling potters is raised. They were moving, due to different spatial situations, while preserving the main and standard features of this period, they have also designed various local motifs on pottery (Askari et al, 2008: 38; Weeks et al, 2010). Another hypothesis is based on the fact that there was a tradition of extramarital relations between local villagers of this period and other areas, which by transferring women to some kind of technical knowledge, vocabulary, and grammar of the decorative patterns of Bakun pottery (Alizadeh, 2004). : 48-49). Also, the phenomenon of nomadic tribes has played a major role in the transportation and exchange of goods produced by the villagers (Alizadeh, 2004; Alizadeh, 2003). Today, Bushehr province and the northern coast of the Persian Gulf are the winter quarters of the Qashqai tribe, so in the so-called winter, these tribes are scattered in all areas of Bushehr province and in the summer in Fars province (Afshar Sistani, 1362: 432). Suzo archaeological evidence also confirms this.
Another cultural period identified in this excavation is Lepuei (contexts 1000-1015). The proposed date for this period is the mid-fourth millennium BC. The diagnostic pottery of this period is simple polished and patterned red vessels, which in some cases are decorated with scarlet motifs. In addition to this type, simple buff ware, gray ware and two samples of Poro Elamite pottery also have been recognized in the fourth-millennium pottery collection of this period. Remains of the mud-brick and right-angled architecture were also encountered under the surface layers, which, due to the small dimensions of the excavation, is not possible to provide a specific function for this structure. According to the architectural evidence, unlike the previous period, it seems that the establishment in this period was permanent and relations with the interior areas of Fars and Khuzestan (according to the samples of the nose-handed jar vessels which are identified on this level) were established. The chronology presented in this paper is only based on comparable and relative studies, but the presentation of absolute dating is inevitable due to the lack of archaeological studies in the prehistoric period in this area, which is hoped to be possible in the future.

The correct position and the determining role of the second and first millennium BC cultures in the Fars region (Marvdasht plain) which we know as the Shoqa/Timuran cultures and the importance of this culture in the transition from the prehistoric to the historical period (Achaemenid) are still not well known. Despite of extensive archaeological research that has been done in the Marvdasht plain and the presence of significant sites of this period, due to the limited and generally very old excavations in these sites, it is still difficult to understand these developments. During that time, huge developments were taking place in Khuzestan and Fars regions; Changes usually created many conflicts between native cultures and southwestern cultures origin (Elamite).Some archaological findings, such as weapons, are signs of the height of such conflicts in the past. This paper will study and introduce the collection of weapons of Toll-e Shoqa, which were obtained from the excavations of Mahmoud Rad in 1942 and Vandenberg in 1950 in that site, those are now kept in the National Museum of Iran. These collections have been studied recently in the inventory project in the National Museum of Iran archives. So far, few cultural materials from Toll-e Shoqa have been published and more emphasis has been placed on its pottery; the pottery is the basis of the relative chronology of this period in the Fars region. Unfortunately, the results of the archaeological excavations in Shoqa were never fully published and all its cultural materials were not introduced. In the organizing project of the National Museum of Iran which will be described and analyzed in this paper.

Abstract
The northeastern region of Iran, characterized by a diverse and expansive landscape, has been a significant area for cultural and commercial exchanges throughout history. The geographical features, including parallel mountain ranges, natural valleys, and basins, have facilitated interactions between the peripheral desert plains, the eastern Alborz Mountain, and the Iranian Plateau with Central Asian regions. The Tepe Pahlavan, located in the northern-southern valley of Jajarm in North Khorasan Province, serves as a valuable example for studying inter-regional cultural trends during the Late Neolithic and Transitional Chalcolithic periods. The present research used a descriptive-analytical methodology to investigate the pottery assemblage retrieved from Tepe Pahlavan in Northeastern Iran during the Neolithic and Transitional Chalcolithic periods. The study aims to classify and analyze the pottery within both the local and regional contexts to comprehend the pottery traditions prevalent during the aforementioned periods. The pottery assemblage of the site indicates its association with the Eastern Sange Chakhmaq and other Neolithic sites from the Shahrud Plain. Furthermore, the presence of the cultural tradition of Cheshmeh-Ali in the settlement sequence of sites during the Transitional Chalcolithic period demonstrates regional and inter-regional cultural interactions. The pottery of this period at Tepe Pahlavan shares common technical features with the pottery assemblages of the Central Iranian Plateau and exhibits less diversity in form and decoration. In summary, the Pahlavan site reflects regional cultural interactions during the Neolithic period and inter-regional interactions during the early phase of the Transitional Chalcolithic period in northeastern Iran with the Central Plateau and the northern regions of the Kopet Dag.

Introduction
The northeastern region of Iran boasts a diverse range of ecosystems, from desert and semi-desert mountains to foothill plains and the Caspian Sea coastline. The Jajarm Plain is a strategically located natural corridor, serving as a vital passageway between the Aladagh Mountains, the Atrek Valley, and the northern edge of the Dasht-e Kavir. Geographically, it is divided into two distinct regions - mountainous and desert - and experiences semi-arid conditions with a dry climate. Tepe Pahlavan is a multi-period archaeological site with deposits from the Neolithic, Transitional Chalcolithic, and Islamic Middle Ages. Although previous surveys and documentation by Spooner, Masuda, and Vahdati had been conducted, our 2017 excavation marked the first excavation of the site. Pottery, as a human-made artifact, offers valuable insights into cultural interactions, socio-economic changes, and cultural changes in ancient human societies. Taking a descriptive-analytical approach, our goal is to classify, typologize, and compare the pottery assemblage from Tepe Pahlavan. This study will provide us with a better understanding of the typological and stylistic characteristics of the pottery assemblage, as well as its cultural significance in the Neolithic and Transitional Chalcolithic periods in northeastern Iran.
Refined Research Questions and Hypotheses: 1. What cultural influences have shaped the pottery tradition of Tepe Pahlavan? 2. How does the pottery collection of this site fit into the regional archaeological framework? 3. In what ways has the pottery tradition of Tepe Pahlavan changed over time in response to regional and supra-regional trends?
After examining the ceramic evidence from Tepe Pahlavan during the Neolithic period, it appears that the pottery tradition might have been influenced by the pottery traditions of the Jeitun-chakhmaq and silk I cultures. Additionally, pottery fragments discovered at sites like Cheshmeh Ali, Silk II, Ghaf Khāneh, and Anu similar characteristics to those found at Tepe Pahlavan, suggesting that they could belong to the Transitional Chalcolithic period.

Discussion
During the Tepe Pahlavan excavation, over 2000 pottery sherds were unearthed and meticulously recorded. These fragments can be broadly classified into two distinct chronological groups: late Neolithic and Transitional Chalcolithic, comprising roughly 45% and 55% of the entire assemblage, respectively. These pottery sherds exhibit a range of sizes and unique features.
The archaeological analysis of the pottery discovered at Tepe Pahlavan during the late Neolithic period has revealed significant technical and visual similarities with the late Neolithic pottery of the Shahrud region. These similarities are observed in the forms, paste color, clay quality, surface coating, baking, and motifs. However, there are some minor differences in some of these aspects. One of the notable differences is the tempering agents used in the two regions. The Tepe Pahlavan group mostly used very small pieces of sand and plant inclusions as temper, while in the Shahrud plain, finely crushed plant materials were primarily used. This difference in tempering agents may have been associated with differences in the availability of raw materials or the preferences of the potters. This characteristic makes the pottery of Tepe Pahlavan more similar to the late Jeitun pottery. The surfaces of the pottery at Tepe Pahlavan have been well-executed, but unlike the pottery of the eastern Tepe Chakhmaq and Deh-Kheir, they do not exhibit glossy or burnished surfaces.
The pottery of the Cheshmeh-Ali culture in the central plateau and the northeast region corresponds with the pottery of the Kopet-Dagh region in terms of forms and motifs. The multiplicity and intricacy of motifs in the pottery of the Cheshmeh-Ali horizons in the central plateau are more significant than those in the northeast region. In the northeast region, such as Tepe Pahlavan, Qaleh-Khan, and Aq-Tepe, unlike the central plateau of Iran, examples of pedestal vessels, basket-shaped vessels, and very large jars are absent. Although the motifs in this type mostly consist of geometric, floral, animal, and a few human motifs like central plateau pottery, these are much simpler and less numerous than those found in the central plateau pottery. The motifs in the early Transitional Chalcolithic horizons of Kopet-Dagh are limited to a few geometric designs, such as oblique ladder-like rows, wide bands below the rim, ray-like bands to the vessel base, vertical frames of zigzag bands, and hatched shapes.
The discovery of diverse pottery at Tepe Pahlavan provides valuable information about pottery making in this region during the late Neolithic and Transitional Chalcolithic periods. The observed similarities and differences in the pottery of Tepe Pahlavan with other regions contribute to a better understanding of the cultural relationships and developments during this period.

Conclusion
The pottery assemblage at Tepe Pahlavan is characterized by two distinct chronological periods. Specifically, the assemblage comprises artifacts from the Late Neolithic period, encompassing Eastern Sang-e Chakhmaq, as well as the Cheshmeh Ali culture which represents the Transitional Chalcolithic period. The findings from this excavation provide invaluable insights into the cultural evolution of the region during these periods. The pottery discovered from the Late Neolithic era within this area exhibits a resemblance to the pottery tradition of the Jeitun/Chakhmaq culture, as well as settlements from the latter part of this culture in the Shahroud and Bastam regions. In addition to the similarities, there are minor differences in certain aspects of pottery-making, such as temper and surface treatment, which indicate local characteristics in the pottery-making tradition of the Late Neolithic at Tepe Pahlavan. These local and regional similarities and distinctions continue into the Transitional Chalcolithic period. Despite the strong resemblance between the pottery of this period and the pottery-making tradition of the Cheshmeh Ali culture in the Central Plateau, there are noticeable local characteristics, such as a reduction in the diversity of patterns and vessel forms.
The available dating samples from Tepe Pahlavan provide evidence of multiple settlements within the time frame of 5800-4800 BCE in the surrounding area. The cultural materials and settlement sequence of this area correspond with the Late Neolithic in northeastern Iran, specifically in Strata 3 to 1 of Eastern Sang-e Chakhmaq within the time frame of 5800-5300 BCE, and the early phase of the Transitional Chalcolithic within the time range of 5200-4800 BCE. This serves as strong evidence of regional similarities between the pottery of Tepe Pahlavan and the surrounding areas and sites of the Central Plateau. There is strong evidence of a correlation between the pottery tradition of this site and the Shahrud region. The cultural materials found at Tepe Pahlavan, along with absolute dating, reveal the emergence and replacement of the Cheshmeh Ali horizon following the Jeitun/Chakhmaq horizon. While Tepe Pahlavan samples have been primarily dated to the 6th and early 5th millennium BCE, there remains uncertainty regarding the replacement of the Cheshmeh Ali culture by the cultural practices of the Transitional Chalcolithic period at a local and regional level. This is largely due to the scarcity of well-preserved layers from the Late Neolithic and early Transitional Chalcolithic periods in the cultural stratigraphy of the area.

Abstract
Iranian architects often designed structures to serve multiple functions beyond their primary purpose, a practice heavily influenced by Iran’s hot, arid climate and long summers. This multi-functionality is most evident in water-associated architecture, particularly in Isfahan’s historical bridges. Despite extensive research on Isfahan’s architecture, this specific aspect of its bridges has been understudied. This research aims to re-examine the non-transportation functions of four Isfahan bridges: Pol-e Shahrestan/Ji, Pol-e Allah-Verdi Khan/Si-o-se-pol, Pol-e Khaju/Shahi, and Pol-e Jubi/Sa’adat-Abad, highlighting their role in ceremonial and environmental landscape architecture. Main Research Question and Hypothesis: The study investigates how and why ceremonial functions were integrated into these bridges. It hypothesizes that this practice was inspired by Indian Jal Mahals (water palaces), introduced to Iran via extensive political and cultural exchanges during the Safavid era. Research Method: This study employs a historical-descriptive approach, with data gathered through documentary research and analysis of historical sources and travelogues. The findings indicate that while the concept of ceremonial water pavilions (Cheshmeh Emarat in Iran, Jal Mahal in India) pre-existed, its application on bridges was an innovation in Safavid Iran. The bridges served as ceremonial platforms for royal events like the Abrizan (Water Sprinkling Festival), receptions for ambassadors, and public spectacles. Furthermore, they played a crucial role in microclimate moderation by creating reservoirs that increased humidity and helped recharge underground aquifers, addressing critical environmental needs of the capital city.

Introduction 
This paper explores the multi-functional design of Safavid-era bridges in Isfahan, which extended beyond mere river crossings to incorporate significant ceremonial and environmental roles. This architectural ingenuity was a direct response to Iran’s challenging arid climate and the socio-political ambitions of the Safavid court. The study focuses on how the bridges Pol-e Shahrestan, Allah-Verdi Khan, Khaju, and Jubi were integrated into the urban and royal landscape. While the paradigm of the water pavilion (Cheshmeh Emarat) was known in Persian and Indian (Jal Mahal) architecture, its adaptation onto bridge structures represents a unique Safavid development. This research addresses a gap in the existing literature by systematically analyzing these bridges not just as feats of engineering, but as central elements of ceremonial life and environmental engineering in the capital.

Materials and Methods 
This research is based on a historical-interpretive methodology. Data was collected through meticulous documentary research, including analysis of primary sources like European travelogues (e.g., by Chardin, Tavernier) and Safavid chronicles. Secondary sources encompass modern scholarly works on Safavid architecture and urbanism. Architectural analysis was conducted by examining historical plans, photographs, and existing structures to understand the form and function of the pavilions. The comparative method is used to draw parallels between the Iranian Cheshmeh Emarat and the Indian Jal Mahal tradition, tracing potential routes of cultural and architectural influence during the 17th century.

Data and Findings 
The investigation reveals distinct evolutionary stages:
• Pol-e Shahrestan: An older bridge onto which an octagonal pavilion (Hasht Behesht plan) was added during the Safavid period, representing an architectural annexation rather than an original design.
• Pol-e Allah-Verdi Khan (Si-o-se-pol): Built by Shah Abbas I, its primary function was connectivity. Ceremonial activities were initially held in the vaulted spaces beneath the bridge deck due to structural constraints, serving as a royal loge for the Abrizan festival and receiving dignitaries.
• Pol-e Khaju: Constructed by Shah Abbas II, it represents the pinnacle of this integration. Two central pavilions (Beyglarbeygi), adapting the Hasht Behesht plan to the bridge’s axis, were purpose-built as ceremonial platforms. The bridge could be dammed to create a vast lake for boating, fireworks, and reflections of upstream palaces like Ayeneh-Khaneh.
• Pol-e Jubi: This bridge provided private access to royal gardens. It featured a central pavilion (now destroyed, but documented in European engravings) similar to the one on Pol-e Shahrestan, offering the royal family a secluded vantage point.

Discussion 
The findings confirm the hypothesis that the sophisticated development of bridge-pavilions in Safavid Isfahan was influenced by cultural and political exchanges with the Indian subcontinent, where the Jal Mahal tradition was well-established. The Safavids adeptly synthesized this influence with pre-existing Iranian concepts like the Cheshmeh Emarat and the ancient Abrizan festival. This discussion argues that these structures were not merely aesthetic additions but vital components of urban infrastructure. They served as instruments of royal propaganda, stages for displaying sovereign power to both the public and foreign emissaries. Furthermore, the creation of artificial lakes through damming was a brilliant hydrological strategy. It addressed Isfahan’s environmental needs by significantly moderating the microclimate through evaporative cooling and critically recharging the subterranean aquifers that supplied the city’s water via qanats.

Conclusion
In conclusion, the historical bridges of Safavid Isfahan exemplify a profound integration of multifunctional design. Iranian architects, responding to climatic necessities and royal ambition, masterfully extended the function of these structures from mere utilities to complex ceremonial platforms and environmental regulators. The practice of adding pavilions to older bridges or incorporating them into new designs was a strategic innovation in the landscape architecture of the era. While inspired by the Indian Jal Mahal, the Safavid implementation on bridges was an original contribution. These structures became iconic urban elements, central to the city’s public ceremonies and essential to its ecological balance. They stand as testament to a holistic architectural vision where utility, ceremony, and environmental technology were seamlessly woven together, defining the grandeur of Isfahan as a Safavid capital.

Abstract
The slag sites under study are located in Khatam County, Yazd Province. In the archaeological surveys of Khatam County in 1400 AH, twelve metal smelting sites were identified through abundant metallic slag, and each of these sites was sampled. Petrographic analysis revealed that the predominant slag is iron, with only one instance of copper slag. The sites where metal smelting occurred, attributed to historical and Islamic periods based on pottery, exhibited evidence of iron smelting and its compounds in eleven samples. These samples contain metallic minerals such as wustite, marcasite, hematite, and magnetite. Marcasite and wustite minerals are related to smelting furnace processes and are products of mineral substances. It appears that in some mines in the region, magnetite and hematite are the predominant minerals, while in others, hematite is the predominant mineral, with a smaller amount of magnetite, which is evident in these primary minerals within the slag. Another sample related to copper slag exhibited small vesicular structures and limited copper ore minerals (chalcopyrite, digenite, and metallic copper) within the slag matrix. Alongside these primary minerals, there is a flow-like green glassy component indicating high furnace heat. The analytical results show that the MgO content in the samples is less than the amount of lime. Therefore, the limestone in this area is mainly ordinary limestone and not dolomite. Chemical analysis revealed that metal workers in this area were more successful at producing sponge iron.

Introduction
Iran has long been recognized as a center for mining and metal smelting. Archaeological evidence indicates that northern and central Iran are among the oldest centers of metallurgy in the world. The presence of rich mineral reserves in Iran, among other factors, has influenced the growth of mining and metalworking in this region (Momenzadeh, 2005). Due to the existence of various metal ores and advanced cultures in Iran, this area can be identified as one of the main hubs of technological innovation in the field of ancient mining and metalworking. Khatam County, located in the southern part of Yazd Province, holds particular significance in the realm of iron slag. One of the earliest efforts to produce steel worldwide took place in this region (Alipour et al., 2021). Considering the evidence of steel production in this area, it is essential (Alipour, 2017) to understand the role Khatam played in iron production during the Islamic and Sassanian periods. To investigate this matter, 12 sites in Khatam County were selected for studying iron slag. The main objective of this research includes petrographic and geochemical analysis of the slag to identify the type of extracted metal(s) and the extraction process and production of metal(s) at these sites. Additionally, the provision of necessary minerals for mining in this area is also under scrutiny. Historical and field research methods were employed for this study, involving the collection of data and archaeological investigations; field studies, such as topographic mapping, photography, identification of sites and metal smelting furnaces; and examination of samples using polarizing microscopes and XRF devices. This research has addressed primary inquiries related to the type of metals in slag, the mining process, and metal production at Khatam’s iron slag sites. Overall, Khatam County held significant importance in the production of metals during ancient and Islamic times. This region is recognized as one of the ancient mining and metalworking centers, and further research into the history and mining processes in this area could provide additional insights into the history of metalworking in Iran.

Discussion
Based on XRF chemical analyses of the slag, the results indicate that the majority of the mineral content in these slags consists of iron ore, with only one case showing the presence of copper. The CaO concentrations in these slags range from 3.59 to 28.41%, and an increase in CaO leads to the production of calcium-rich olivine. The type of slag (flow, permeable, massive, or furnace bottom) significantly impacts the results of chemical analysis and the ratio of oxides of the main elements (metallic oxides and silica). Additionally, the high amount of CaO facilitates the formation of a calcium-rich silicate phase. Petrographic microscopy studies confirm these findings, revealing observable olivine phases and primary silicate phases with metallic iron minerals such as magnetite and hematite. Due to the silica content, the addition of limestone to the smelting process increases the amount of duplex iron (Fe3O4). Consequently, silica stabilizes triplex iron oxide (hematite), while limestone stabilizes spinel iron oxide (magnetite). Moreover, microscopic examinations primarily reveal metallic minerals such as magnetite and metallic iron. Furthermore, sponge iron, like many other ancient civilizations in the region under study, was produced. The production of this type of iron requires less technical knowledge than other types of iron (Abbasnejad, 2009).
Surveying the region revealed that plants such as pistachios and wild almond produce high-quality charcoal. Since blacksmiths have no idea about using additional limestone in the furnace, the smelted slags were highly adhesive, leading to significant iron loss. The use of limestone in iron removal creates slags with fine properties that are easily separated from the iron (Abbasnejad, 2009). A good slag resulting from smelting should contain 30 to 40% limestone. Tests conducted on iron ore in this region show limestone percentages ranging from 3.59 to 28.41%. The slag analysis results also indicate a small amount of limestone, averaging approximately 11.38%. The deficiency of these two elements in slag, as they play crucial roles in reducing smelting heat and separating iron from slag, can indicate high iron levels and the inadequacy of slag (adhesiveness, viscosity, high density), resulting in low-quality sponge iron. The percentage of Fe2O3 ranges from 23.20 to 74.25%, and the percentage of Al2O3 ranges from 0.003 to 0.94%. The percentage of MgO in the tested slags is less than 0.003%. According to the mineral analysis, the most important iron minerals in this region include hematite (Fe2O3) and magnetite (Fe3O4). Due to technical flaws in these furnaces, sponge iron contains impurities such as silica, phosphorus, aluminum oxide, manganese oxide, and other metallic oxides, as confirmed by various tests conducted on ore and slag.

Conclusion
Eleven samples from the metal smelting site showed evidence of iron smelting and its compounds. In these samples, metallic ores such as wustite, marcasite, hematite, and magnetite are observed. Marcasite and wustite ores are related to smelting furnace processes and are mineral byproducts. It seems that in some mines in the region, magnetite and hematite are predominant, while in others, hematite is less prevalent, and magnetite dominates. Additionally, in the sample related to copper smelting slag, small and limited vesicles of copper ores (covellite, digenite, and metallic copper) are observed alongside a part of the green glassy matrix, indicating high furnace heat. This primary mineral evidence is observed in the slags. Considering the changes in the calcium oxide (CaO) concentration, it can be inferred that this substance was added during smelting operations to aid in smelting and reduce the temperature of the furnace materials. The microscopic results of some slags reveal primary minerals, mostly hematite and magnetite metallic ores, indicating a magmatic origin for the utilized minerals. The percentages of silica (SiO2), magnesium, and aluminum in these slags are relatively low. Analyses of these slags and iron stones from this region show that a deficiency of CaO and SiO2 leads to iron loss in the slag while increasing the iron content within it.
Based on this research, it is likely that iron ore was extracted from mines near the site and was subsequently transported to this location. Given the presence of iron mines at distances of 8, 10, and 15 kilometers from these sites, these mines are likely the source of these slags. Regarding the archaeology of the region, historical references indicate that the area held significance and prominence in various historical periods, particularly during historical and Islamic eras. However, due to insufficient information about the archaeology of the region and the lack of precise dating of these sites, accurate dating of these sites is unfeasible.
