Abstract
The most important way of understanding human being in the past is to study their relics and among the works that have made a significant contribution to identifying culture and civilization and many other issues of ancient Iran, the motif are seals. Studies of this kind of data have been the focus of archeologists and historians for many years and many articles and books have been published on this endless subject. Because the seal and sealing in answering some questions, the correct orientation of a number of questions and new questions about social, economic and people perceptions of the past have been raised. In some motives the artist describes his/her world and this kind of description is actually the optimal use of symbols. In the Persepolis museum, there is a black seal that differ substantially from other Achaemenid seals. This bilateral seal is a lesser-known role in the art of molding and is unique in Achaemenid molding. This seal is first published and revised based on various criteria such as art style and symbol interpretation. The main purpose of this article is to document and introduce the symbols of this seal; the author will also answer a few questions about this seal by using descriptive-analytic methods and by using authentic library resources after fully describing this seal. First, what are some of the concepts used on the engraving on the seal? How these symbols originated and whether these forms were the result of Achaemenid thought or a legacy of a very ancient culture?
Keywords: Seal, Achaemenid, Persepolis, Symbol.

Introduction
On the occasion of the plan of organizing the repositories of the Persepolis museum in the summer of 2015, I had a black seal on a meeting in august of that year. This seal had differences A double-sided stamp seal that is unique in the Achaemenid period. On the other hand, the seals have a special place among the represent the customs, habit and believes of a people and also showcase history, religion, philosophy and art alongside administrative. Social management for centuries, these motives are rooted in ancient Iranian civilization and sometimes influenced by neighboring nations. This portable data has also spread art and culture to other lands due to its use in commercial exchanges, office letters and political relationships. The main purpose of this article is to document this seal and to interpret the emblems that have reached the Achaemenid from the distant past. Recorded in the Persepolis museum of bilateral seal No. 1267. It has a diameter of 15 mm and a thickness of 9 mm. It is made of stone and its location is Persepolis. There are three distinct roles on the seal. First the man sitting and holding a bowl in his hand and a flower in his other hand. The second is the cedar tree behind the man, and the third is censer in front of the man. The man is Probably a king with a short crown, the hemisphere is like the Achaemenid image.

Identified Traces
Three separate images can be seen on the seal, first is the man sitting and holding the wine cup in one hand and the flower in the other the second is the cedar tree behind the man and the third the udsuz in front of the man.
The man is probably a king with a short crown with several congresses, it is depicted from the half- face like the other Achaemenid image, the crown is similar to the Ahura Mazda round Cap. On the king’s seal has the original image and the role of cendar and is quite marginal.
Beneath the crown of hair, curly like all the motifs of persepolis the forehead and back, the king’s face wide and his eyebrows reached the ears, the nose is delicate, long and straight, lips are up and drinking and beard shorter than persepolis motifs but curly, the king’s eyes look great. The king’s neck was proportioned to the body, part of which was nuder the dress, the king’s hands are long and stretched and he looks thin. The king has a lotus flower in his left hand with a bud in his right hand corner, like Darius in the Naghshe Baram. The branch of the flower is tall and its end protrudes from the king’s hands. The king has a large wine cup in his right hand that lifts it up or closes it. The king’s waist is slender and its curvature is quite evident, and the belt is wrapped in two rows around the king’s waist. The king’s feet are on the ground and parallel to the base of the chair. The king’s Boot is a long boot with twisted straps that are not simple in the designs attributed to king Boots, but a simple shoe. Behind the king is a small triangular cedar, there are ten rows of branches on the left and eleven branches on the right of the cedar tree. The branches have all gone upwards and look like praying hands.
It is noteworthy that most tree motifs are on the palm tre seal and less than the cedar tree. Lion painted on a young and very angry seal seems to be a characteristic of most of the lions imprinted in the Achaemenid period. The body of lion is soft and agile, his head turned back. The hands and feet are in a relaxed gait so that the lion triumphantly moves forward the bird on the seal is Dorna that wing has been opened it seems that the artist insisted on drawing the head and neck of the Dorna so as not to induce the role of the Farrah.

Conclusion
Prehistoric believes of Iranian ethnicity have had such a broad role in shaping Iranian art that it is still visible in many works of art, an example is the seal studies. At a time when most of the seals built during the Achaemenid period are cylindrical, a bilateral seal imprinted on Persepolis is the most famous and important Achaemenid city, all the carved motives on it reflect the millennial believes of the Iranian people, some of which still have the same implicatins for contemporary people. None of the motives were devised by the Achaemenid artist, rather, old concepts in a new way with new technology and sophistication are on the seal.

Abstract
The expansion of the Seleucid realm in the east and its need to dominate the Iranian people led to the creation of pro-Greek bases by forcing its Greek-Macedonian subjects to emigrate into the eastern lands. The construction of new colonies along the eastern trade routes and their politico-economic performance strengthened the Seleucid rule and made it more enduring than the Macedonian empire of Alexander the Macedonian. The existence of Hellenistic colonies in Central Asia led to the sending of large numbers of Greek-Macedonian immigrants to the region, which themselves opened a new window on Eastern-Western trade. Based on the archeological data and historical texts and using the descriptive-analytical method, the present article intends to clarify the nature of Seleucid urban planning and the difference between colonies and poleis. Then it will explain the reasons for the creation and function of colonies in Central Asia and the Iranian plateau. Since the focus of previous research has been more on how to build and rebuild Seleucid cities in Syria and Asia Minor, the present study seeks to focus on the question of why the Seleucids intended to build different colonies and cities. The research hypothesis is that the Seleucids, in addition to their military use of these cities, also considered their economic use, especially when one can see that these colonies, which later became large cities, were located along the eastern trade routes, which played an economic role. 
Keywords: Seleucids, Urbanism, Polis, Colony.

Introduction
During the rule, the Seleucids ruled over a wide range of civilized lands in the ancient East, and in the broadest sense, they controlled the borders between Polis and Syria. They established colonies and Polis to gain more control over their open lands and to build popular bases in these lands to strengthen their power bases in the lands that previously belonged to the Achaemenids. Formating. the idea of colonizing and creating barracks, there is a legacy of Alexander the Great during the time of his conquests, which was the import of digital and social construction of the liberated lands. The arrival of Ionian-Macedonian immigrants in the area between Mesopotamia and the ancient East was a turning point in the culture and civilization of Hellenism during its lifetime. In a way, the center of gravity of the Hellenistic base is transferred from the west of the ancient world to the eastern part, and until the last days of the life of the Hellenistic empires in Syria and Egypt, it is necessary to try to survive.
The active presence of the Polis in the rise to power or overthrow of the Parthian emperor’s Citizenship or disobedience to the commanders of the Roman civil war and the Polis and then their lives in the time after the most important Seleucid heritage in the east of the budget. Therefore, the present study aims to first clarify the nature of colonies and Polis and then answer a few questions about them. Among the policies of colonization and urban planning (Polis) in the Seleucid Empire, have they been carried out on a planned basis or not? Has the Khorasan road been a clear trajectory for the establishment of a colony? Did the location of the colonies and the Polis play a role in the creation of trade roads in later periods?

Conclusion
The Seleucid emperors faced many problems during their lifetime, including the heterogeneity of tribes in the vast geographical region of their rule. An important part of the protests and revolts against this non-Iranian dynasty was the non-indigenousness of these people. Although Seleucus the 1st  tried to eliminate this position of the Iranian tribes towards himself by choosing Antiochus I, an Iranian mother, as his successor, but as we have seen, he did not succeed much. The Seleucid emperors found a way out of this situation by establishing popular bases within their lands. He took the first step to legitimize himself by establishing colonies and migrating the Greek-Macedonian population to these places throughout his lands. The Seleucids, with a clear understanding of the position of the colonies from a Geo-political and Geo-economic point of view (Geo-economics) in the lands under their control, sought to strengthen and expand some of these colonies to establish stronger bases for themselves in Although in some places, such as Central Asia, the weakening of the Seleucid government was accompanied by the declaration of independence of the Central Asian Polis from the Seleucid Empire, in some areas the Seleucids had better control over those areas. The Polis and Polis remained under their yoke, although with the collapse of the Seleucid regime in Iran, the colonies gradually dismantled or became a small town, for many years the Hellenistic Polis played a key role in Iranian politics. Thus, the undeniable role of the colonization policy in the ups and downs of the Seleucid government can be considered and it was concluded that with the decline of the importance and credibility of the colony, the Seleucid government lost its strategic base and the rhythm ended. The lifespan of this dynasty intensified.
 

Abstract
In the repository of Persepolis Museum, there are about 700 pieces of inscribed stones related to the cinctures of Persepolis Palaces, almost all of which are broken and incomplete. It us noteworthy that all the pieces are incomplete and broken in one place and only one cincture in the museum hall is complete and the rest of the pieces are all incomplete. Even the healthy piece was broken at the same point where the other cincture were broken and later repaired. All these fractures and defects have been done intentionally and from two specific places. About 40 of these pieces belonged to Thatcher Palace, and after their arrangement and reconstruction, 12 cinctures were obtained equal to the number of Thatcher Palace columns. In all this number, the name of Xerxes is seen as the builder and there is no other name of the Achaemenid kings. The sculptors have followed a certain pattern for their work. Apparently, all the pieces have inscriptions and these inscriptions were in three living languages of that time, namely ancient Persian, Elamite and Babylonian, and all the inscriptions were carved with cuneiform. These three civilizations were the most important civilizations of their time and they certainly had interactions with each other. In this article, we will try to study the cincture inscriptions of Thatcher Palace columns by descriptive-analytical method. How many paragraphs dose the writing contain and what does it contain? The three languages are compared and analyzed, their differences are identified and finally the cause of their breakdown is investigated. 
Keywords: Cuneiform, Cincture, Persepolis, Thatcher Palace.

Introduction
The common script in Achaemenid times is cuneiform, which some scholars attribute to the previous kings of Darius and even the period of historical beginning (Young, 2007: 38). Elamite was the official language and Aramic language common is most areas under Achaemenid rule. But it should be considered in mind that with the vastness of the Achaemenid territory, there were certainly many linguistic differences in this land, which according to recent linguistic research, probably more than 10 languages were common in this territory, (Anthony, 2013,37). The number of inscriptions from the Achaemenid period that have been discovered so-far is over 40 inscriptions, the most famous of which is the great Bistoon, which is written in three languages: ancient Persian Elamite and Babylonian. With the coming to power of Darius, this line was completed so that the types of verbs and their tenses, as well as pronouns and objects and the construction of verbs in it were well observed, and because it was based on grammar, it was possible to decipher it. It is noteworthy that the cuneiform is the only line that there is slash sign between words, and this feature led Rawlison to decipher it for the first time, and then the starting point for deciphering other lines, such as the Babylonian, Elamute and Assyrians...... The main goal of any linguistic research based on a silent language is to go through the veils of historical and cultural language and to achieve a correct understanding of the inscriptions and a report that is as enlightening as possible, in addition, providing an opportunity to teach a silent language has been a sub-goal of this research. In this research, apart from the ancient Persian language, the Elamite language of the Achaemenid period, which was strange in its birthplace, Iran, has been studied. Unfortunately, less of this research has been by domestic researchers in the field of ancient Iranian languages in the field of Elamite language. Thatcher Palace, column and its cinctures.

Discussion
Thatcher’s stone cinctures in Persepolis are divided into three categories in terms of material, shape, color, and size. 
1. Cinctures made of limestone which has a light gray color and in terms of shape and form has a simple cut and no geometric tools and on it inscriptions in three languages of ancient Persian, Elamite and Babylonian in a very beautiful, technical way carved without the slightest fracture. All letters and symbols have a dimension in the sculpture and have elongated symbols and are neither short nor long due to the small space. For this reason, this type of current is called cuneiform by Nasta’liq writers. (picture7). This cincture sample has not been found more than two samples so-far, for this resin, this specimen must belong to the columns inside Thatcher Palace Hall. The stones with which the sculptors used to build these types of columns were extracted from the mines of the same area. (picture, 1,4,5). 
2. The cincture is made of decorative stone or hematite, which is glossy black, this type cincture is smaller in diameter and height than the other two, similar in shape to the first sample, which is made of limestone. The reason for the simplicity of this sample is probably the high degree of hardness of the lathe. On this cincture unlike the first sample, trilingual inscriptions with cuneiform lines are carved in a row and in the same order, a few centimeters apart. In this way, the last sign of the Babylonian cuneiform, which is the end of the inscription, is located a few centimeters behind the beginning  of the ancient Persian inscription, the carving of the symbols and letters on it were simple and had no dimension, and perhaps due to the hardness of the stone, they used narrow and simple symbols and letters, and had no small, crushed pieces and also there are two samples of this cincture, one almost complete, which attracted the inside the Persepolis Museum, and the other was half of cincture that was placed in the tank of the same museum. (Picture 2 and 8). 
3. Cincture made of decorative stone and light blue color with a gutter tool around its upper edge, also this cincture is larger in diameter and height than the other two types, and triple cuneiform are carved in a row on it. This type of cuneiform has beautiful but it does not have concave dimension and beauty of the first type. (Picture 3and 6). The size of the cinctures starts at 5 Cm and covers up to one third of a cincture. Its inscriptions were masterfully sculpted in ancient Persian, Elamite and Babylonian languages. After arrangement, the pieces reached 12 cincture, which were the number of columns in the Palace. After translating each word, it replaced them and finally a text was obtained that was repeated 12 times in 3 languages. The important point with our discussion was that a common part this text disappeared in the sentence and then continued the sentence to the end.

Conclusion
When Alexander entered Persepolis, more than two centuries had passed since the Achaemenid Kings ruled the world, and more than one hundred and seventy years had passed since the construction of Persepolis. Conqueror historians have written that after Alexander’s conquest of Persepolis, he ordered it Tobe burned while intoxicated at the request of his mistress, and they know this commandment against his inner desire and try to remove this shameful act from his face on the other hand, if Xerxes or his father Darius, he immediately rebuilt it, although such an action, ie the burning of Athens by the Achaemenids, was never reported. With these details, the authors of this article found that the fire and destruction of Persepolis had nothing to do with the above story, Greek soldier, consciously and under Alexander’s direct order, destroyed the inscriptions, symbols and looted the architecture and its treasures. When they translated these inscriptions for Alexander, he saw himself defeating the Achaemenids without a rival to the emperor of the world. As a result, he ordered the destruction of all inscriptions that had such meanings, especially titles such as king of the world etc., for this reason, broken pieces were not found when translating the cincture. There is also a broken statue of Darius in the treasury of Persepolis, which is clearly visible due to the strong blow, especially the left eye of the statue, which is split on both sides and the place of the blow corresponds to the arrow of Alexander’s soldiers, and as you fill the gap with the sculpting paste, it becomes an arrow, the same shapes can be found at the fracture site of the cincture.

Abstract
Obviously Persepolis is one of the most important archaeological sites in the world. Numerous scholarly works have been published about this site since the last century. However, this article stresses on a specific and new topic concerning a tool on shoulders of an Indian among India’s delegation in Apadana Palace of Darius the Great. The portrait of the delegation has been pre-served in the eastern and (damaged) northern staircases. The author, unlike previous works, be-lieves that this tool reflects a bamboo-stick which is known in India.  Indians used accessible bamboo-sticks, as a native plant, to carry their loads. They put a bamboo-stick on the shoulders while tied two containers in its two sides. The bamboo-stick is also widely used in ritual cere-monies (Hinduism). Clearly, to transfer the holy water of Ganges River to Shiva temples, pil-grims use a bamboo-stick tied to two containers. The bamboo-stick has been a significant tool in Kanwar Cult or Kanwar-yatra in India. Furthermore, Krishna’s Flute is made of a bamboo wood! In the famous Indian story of Shravan Kumar, this devoted child takes his blind parents to pilgrimage with a tool exactly like the one depicted in Persepolis, two baskets attached to bamboo-sticks on the back. Flexible bamboo-stick does not hurt the shoulders, it is easier to control with both hands and it is less likely to break. For this reason, these flexible sticks - un-like scales - do not need handles in the middle and fastenings at the two ends with their bas-kets! In fact, the Indian bamboo-stick carrier arrived at Darius the Great court with a pure Indi-an traditional manner. So, the author relying on the special standing of bamboo stick in Indian culture ranging from ritual ceremonies to the life style challenges previous scholarly works on this subject.

Introduction
Obviously, Persepolis is one of the most important archeological sites in the world. Many sci-entific works have been published about the site since one hundred years ago. Persepolis is lo-cated 60 km northeast of Shiraz in the Marvdasht plain. Around it, the glorious heritage of the Achaemenid to the Sasanian Empire can be seen on the mountains and valleys. The oldest de-scription of Persepolis, according to Diodorus Siculus (Herzfeld, 1941: 230), is based on ac-counts of Alexander’s appearance in the East. Nevertheless, Iranian geographers of the first Is-lamic centuries such as Mas’udi, Ibn Balkhi and Moqadasi ... have also pointed to this area in-tertwined with King Jamshid (cf. Akbarzadeh, 2014: 36). This magnificent national historical site was registered in the UNESCO World Heritage List in 1979.
From the late Qajar period, western scholars began exploring and studying ancient sites and Persepolis was one of them. Shapur Shahbazi (2009: online) has referred to a list of these peo-ple. Among them, I should refer to the masters like Schmidt (1953, 1957, 1970; Herzfeld,1941; Stronack, 1961-1963; Behnam, 1939, Mostafavi, 1951, Shahbazi, 1976) and etc.

Topic of the Article
However, the subject of this article is a new research on the portrait of a tax-paying Indian del-egation on the eastern (also damaged northern) stairs of Darius the Great’s Apadana.
An Indian (of the delegation) is carrying something like a scale (according to previous work i.e Schmidt, 1953-1970; Root, 1979, Callieri, 2004: online; Briant is silent; Briant, 2002: 268). Meanwhile, the main question is that: Can this tool be a scale?
This tool, which is the main topic of this article, will be discussed according to a photo about the delegation (Persepolis). To challenge the previous works, I will refer to Indic texts where I will describe some old significant Indian rites.
In the photo, a long carrying stick all over the man’s shoulder (with protrusions on both sides), two cheek baskets that hang from the end of each piece of wood, without any fasteners is clear-ly visible. Moreover, the man’s hands are the most important factor in maintaining this flexible wood attached to heavy baskets on both sides. The powerful Achaemenid craftsman accurately displayed the flexibility of the wood.

Discussion
A look at the scale’s forms in the ancient world from the Hellenic borders to Egypt and Iran (Buttner & Renn, 2016: 757) as well as text studies (see next) clearly diminishes belief in that the Indian man is carrying a scale!
However, to answer the main question: I should note that this tool can never be a scale as all western and Iranian scholars have been convinced. I would explain it as a bamboo-stick, the fa-mous native plant of the country (India). This plant can be seen all over India, especially along rivers and valleys. The Indians have widely used (even today in villages) flexible bamboo wood to carry light cargo.
In the famous Indian story of Shravan Kumar (Balasokulam, 2005: no. E32), this devoted child takes his blind parents to pilgrimage with a tool exactly like the one depicted in Persepolis, two baskets attached to bamboo-sticks on the back. “Once upon a time, when king Dashrath ruled, there lived a boy named Shravan Kumar. His parents were old and blind. He had to do all the works for them, since they couldn’t see. One day, Shravan Kumar’s parents expressed their de-sire to go on pilgrimage. As an obedient son, he wanted to fulfill their wish; but how would he do that? He couldn’t afford any transportation since he did not have money. He found another way. He took a strong bamboo-stick, tied baskets at its two ends and placed his parents in those baskets…” 
Furthermore, the bamboo-stick is mingled with the Hindu beliefs. Krishna normally appears with a flout which is made of bamboo! Sacred Ganga water carries by bamboo-stick (Kanwar) to Shiva Shrines.  In fact, Kanwar (Kanwar-yatra-) is a genre of religious performances where participants ritually carry water from a holy source in containers suspended on either side of the pole (cf. Singh: 2017, 46). 

Conclusion
The author believes that the portrait of that Indian tribute/gift bearer in Persepolis is only a re-flection of an Indian tradition in which Indians carried their goods in this way. It is strongly be-lieved that the two baskets at the two ends of the stick are the least reason why some scholars have confused it with the scales. In fact, this Indian man, according to his tradition, has brought a gift to the king! The multifunctional bamboo-stick of Persepolis (Skt. Vaina-, Hindi. Behngi and Kanwar (Bihar), probably Sogd. wn-, wn’kh (Apte, 2006: 27; Gharib, 2004: 408) were strongly supported by Indic texts and religious rites. In the story of Sravan Kumar, the loyal child took his parents to the pilgrimage by a bamboo-stick tied to two baskets! Also, Kanwar rite is one of the most important Hinduism beliefs where the bamboo-stick plays a significant role.
A part of religious aspect, flexible bamboo-stick was controllable by hands and it was accessi-ble and none-costly in all parts of the country.  Also, Indians were skilled to bring things by such bamboo-sticks. 
So, the craftsman recorded a detailed Indic tradition in the court of the Achaemenid king, Dari-us the Great, where this Indian man arrived with a bamboo-stick and nothing more. The author thinks that the bamboo-stick’s flexibility is a reason that some scholars mistakenly supposed some heavy things like gold stones (cf. Shahbazi, 2002, 268) can be referred in the boxes (of the baskets). 

Abstract
It is possible to study the climate adaptability of past and present architecture by benefiting from the sciences of archeology, architecture, geography, applied climatology and paleoclimatology. Conducting such studies in connection with the complex of Persepolis in Marvdasht plain belonging to the Achaemenid period adds new information to the scope of our knowledge of the architecture of the mentioned period. The current research seeks to evaluate three main questions: 1) What were the physical components of the architecture of Persepolis complex in order to adapt it to climatic conditions? 2) How effective were these components in line with the mentioned issue? And 3) What were the non-physical heating or cooling arrangements of the complex? The necessary information has been collected by library and field methods and analyzes of four software, AutoCAD, Climate Consultant, Ecotect, and DesignBuilder in the field of energy and architecture and processed in a descriptive-analytical way. The physical components of the architecture of the complex include its orientation towards the south with a northwest-southeast stretch, high density and height of buildings and the creation of passages with a small width, the use of mud-brick in the construction of walls and the creation of a flat covering of wooden beams, the installation of side doors and windows in the walls. South in most of the buildings are the construction of the pillared porch at the entrance of most of the buildings. These components are effective in using the radiant heat of the sun to heat the residents in some hours in the time range from October to April. However, the application of these solutions from November to March (1632 hours in total) is not enough, and heat production was needed. Probably, in order to achieve thermal comfort, the residents had time management in holding gatherings and used non-physical heating arrangements similar to portable open fire-place from the palaces of the Assyrian Empire. Finally, the climatic adaptability of the complex to the Marvdasht plain and the adoption of suitable heating and cooling measures in it have ensured the thermal comfort of the residents.

Introduction
Creating ecological stability between man-made and nature is necessary for the continuation of life. Architecture is one of the aspects of human life that has a direct relationship with climatic conditions. The formation of native architectural styles throughout history shows the extent of knowledge of the ethnic groups from the climatic conditions of the surrounding environment, which is based on the reading of the geographical, historical and social background of the region (Moazzen & Sad berenji, 1400: 168). When the climatic conditions in a region are favorable, human life is formed and continues there. These conditions are different in different parts of the world and it is necessary to use elements in the architectural body of the building with the aim of complying with the mentioned conditions. Archaeological evidence shows that humans have been aware of this issue since prehistoric times and have taken steps towards the optimal use of natural factors and reducing their negative consequences. The architecture of the residential and religious buildings discovered in Tepe Zagheh (Malek Shahmirzadi, 2011: 326-327) and the architectural works obtained from the V cultural period of the Tepe Sagzabad (Talaei, 2015: 145-145) are proof of such knowledge. By adopting suitable cooling and heating measures in the architectural body of the building, a mental condition is created in the residents that express their satisfaction with the thermal conditions of the environment, and it is called the thermal comfort range (Hejazizadeh & Karbalai Darei, 2014: 22).
Historical documents and archaeological data related to the Achaemenid Empire have been discovered from different parts of their territory, and architectural remains are among these discoveries. The architectural complex uncovered in the vicinity of Persepolis in Marvdasht plain is one of the architectural remains left over from the Achaemenid period. The architecture of this complex is in a way that has certain proportions and the Peymoon system (Javnmardi & et al., 2018: 123). The architectural body of each building must match the climatic conditions of the surrounding environment as much as possible in order to ensure the thermal comfort of its inhabitants. If the physical adaptability of the architecture is not enough, cooling and heating measures are taken to produce cold or heat in the building. The problem of the current research is to know the physical components of the architecture and the heating and cooling solutions thought in the architecture of the Persepolis complex in accordance with the climatic conditions of the Marvdasht plain, which can bring information about the adaptation of the architecture to the climatic conditions in the Achaemenid period.

Identified Traces
The physical components of the Achaemenid architecture of Persepolis, in order to implement these arrangements, include the orientation of the complex in relation to the azimuth of sunlight towards the south with a northwest-southeast extension, which is exposed to an average of the maximum amount of solar radiation energy and its optimal value. Due to the gradual construction of the complex, the high density and height of the buildings has caused the creation of passages and two courtyards with a small width, which has reduced the area of the movement field of unfavorable winds, shading the openings on hot days and causing a lot of failure in the passages. The use of mud-brick in the construction of walls and the creation of a flat covering of wooden beams with a large thickness, which has a high capacity and thermal delay, prevents the loss of heat on cold days and reduces the entry of heat from the outside into the interior of buildings on hot days. Installing openings in the northwest-southeast azimuth is an average of the maximum radiant heat (east) and optimal (east-west with south view) azimuths, and the amount of heat received from sunlight is suitable for hot and cold days of the year. Most likely, the doors and windows are closed on cold days. The construction of pillared porches in most buildings also played a role in adjusting the air inside. Applying these solutions in most of the hours from November to March, which is calculated as a total of 1632 hours, is not enough to ensure the thermal comfort of the residents of the complex, and heat production is needed.

Conclusion
Considering the great and well-studied achievements of the architects and master craftsmen of Persepolis in various architectural, technical and artistic fields, it is expected that they will have significant achievements in the field of adaptation of architecture to the environment and heating and cooling arrangements. Based on the analysis of the climatic conditions of Marvdasht Plain and the thermal comfort of its residents, it is more necessary to comply with the heating measures compared to the cooling measures in the architecture of a building in the mentioned area for climate adaptation and providing the thermal comfort of the residents. Natural heating measures include the use of heat from sunlight, which relieves the cold stress of the residents in some hours in the time range of October to April. The cooling arrangements also include shading on the openings and natural air ventilation, which provides thermal comfort to the residents from April to May and from September to October in some hours and in the middle days of the two mentioned periods at all hours of the day and night. There was no need for cooling during the year. In this collection, wall-mounted heaters similar to the examples of the third floor of Babajan Tepe Lorestan have not been identified. For this reason, it is likely that the inhabitants used portable metal fire-place similar to the Assyrian types and provided the necessary heat. Finally, the present research shows that the architects of Persepolis complex, as well as having mastered various architectural techniques, also had sufficient knowledge in relation to various aspects of climate adaptability and the adoption of heating and cooling measures in order to ensure the thermal comfort of the residents in different months of the year.
