Abstract
The anthropomorphic monoliths culture has been common for several thousand years, from the western borders of China to the Baltic Sea and Spain, and it has been manifested in various forms in archeological findings and written sources in the Eslamic eras. It seems that the most important reason for the temporal expansion of this culture lies in its religious and ritualistic nature, and what caused the spatial expansion of this culture was probably related to commercial exchanges and, as a result, cultural exchanges. The anthropomorphic monoliths can be seen in human and animal forms and symbols of fertility The current research tries to answer these questions that what are the most important factors of temporal and spatial expansion of the anthropomorphic monoliths culture of anthropomorphic monoliths? And what are the concepts used in the anthropomorphic monoliths, culture in the prehistoric and Eslamic eras? The present study, while examining the temporal and spatial expansion of this culture and introducing its key examples in the geographical area between the Black Sea and the cultural area of the Caspian Sea, investigates the meaning of the erection of the anthropomorphic monoliths This type of research is of a cultural-historical analytical type, the information of which is collected based on documentary and library studies The results of the present research show that the most important factors in the temporal expansion of the anthropomorphic monoliths culture were due to their relationship with traditions and religious rituals, and what caused the spatial expansion of this culture was probably related to commercial exchanges and, as a result, cultural exchanges. Also, over time, the anthropomorphic monoliths can be seen in human and animal forms and symbols of fertility, which in many cases have been manifested in the form of the deceased person in connection with his burial. The results of the present research show that although there is no chronological and archaeological connection between the pre-historical and AD samples, all the samples are related to the ritual burial of religious rituals and represent a person who probably has a high social rank. This issue has been reflected in the archaeological texts.

Introduction
A stele refers to raised anthropomorphic monoliths or stones that are erected vertically in the ground and have a memorial status and are related to burial ceremonies (Darvil, 2008). Stone steles in the shape of humans or with human motifs have been reported in a wide geographical area from the western borders of China to the Baltic Sea and Spain (Tryjarski, 1971: 127). Russian and Azerbaijani archaeologists have carried out preliminary research activities in the direction of identifying anthropomorphic monoliths in the Caucasus in the meantime, some sources have studied the culture anthropomorphic monoliths in different regions in a monograph form (Schachner, 2001, 115, 142; Sevin, 2005; Ngrahamn-Summer, 1979: 68, 70; Burney, 1979: 155-156). Shahryeri site as one of the most important sites for the development of the anthropomorphic monoliths culture was explored by Alireza Hojabri-Nobari during three seasons (Hojabri-Nobari et al., 1379). The anthropomorphic monoliths of the Tabriz Museum were probably obtained from Qara Dagh region in the northwest of Iran. These anthropomorphic monoliths were first visited by the German researcher Gert Grupp (Torabi Tabatabai 490: 1355). The anthropomorphic monoliths of the Tabriz Museum were recently introduced and reviewed by Adel Yilmaz in 2012 (Yilmaz 2012). Therefore, the latest research has been carried out in Iran regarding the anthropomorphic monoliths in the Shahryeri area and the cultural relations between northwest Iran and the Caucasus (Khanali, 1379). So far, there have been many theories about what this culture is, although it is not far from the mind that these memorial stones were erected in different human societies with religious, promotional and social purposes. (Sevin, 2005: 89). It is necessary to explain that this culture has been exhibited in many graves in different societies from prehistoric times (Agasioglo, 2013) to recent centuries (Yilmaz, 2003: 44). Although the relationship between the anthropomorphic monoliths in the Shahryeri area and the burial graves was previously denied (In: Graham & Summers, 1979), the author’s recent research shows that this culture has a direct connection with the burial graves in this area. The anthropomorphic monoliths culture is one of the cultures that can be seen in the northwest of Iran due to the cultural connection between Iran and the Caucasus. The present research, while examining the temporal and spatial expansion of this culture and introducing its key examples in the geographical area between the Black Sea and the cultural area of the Caspian Sea, investigates what and why based on the anthropomorphic monoliths Undoubtedly, traditions and burial rituals in human societies do not undergo changes easily, so it seems that the most important reason for the spread of this culture from the third millennium to the end of the first millennium BC in a time span of more than 2000 years in the vast geographical area of Anatolia is probably the Caucasus. It has been related to commercial exchanges and cultural exchanges as a result.

Investigating the concepts and scope of the temporal and spatial expansion of the culture of anthropomorphic monoliths
At the end of the 3rd and the beginning of the 2nd millennium BC, the anthropomorphic monoliths culture appears in connection with Nomads tribes in different regions of the Republic of Azerbaijan (Fig. 1) (Schachner, 2001: 132). The anthropomorphic monoliths of Dobandi village in the north of Baku was found in connection with Gori cultural materials belonging to the late Maykop culture period (Ibid: 123). The second example from this period was found around Astara city in Azerbaijan in the second millennium BC in Syria and Anatolia, anthropomorphic monoliths a special respect, so that they were often placed in front of the gates and protected the place from the entry of evil spirits. At Tell Chana in Antioch and at Tell Rimah, anthropomorphic monoliths slab similar to examples from the Caucasus region and northwestern Iran have been found (Carter, 1970: 22). 
Since the end of the second millennium, 13 stelae have been obtained from the carving site of Turkey (Ozfirat, 2002: 299). In the first millennium BC, we see the number of anthropomorphic monoliths in the region This importance is undoubtedly directly related to the increase in the skill level of using metals, especially the use of iron metal (Khanali, 2017: 461). The samples belonging to this period were obtained in Shahryeri area and Qara Dagh region of East Azerbaijan Considering the sanctity of the Shahryeri area, it seems that different people have prepared memorial stones for themselves or their deceased relatives to have a memorial in this sacred area. An example of burials without corpses in the geographical scope of the Balkhi-Marvi culture (Tughluq, Ganor) (Sarianidi, 2007: 51) in the city of Sokhteh in the southeast of Iran in the period (2500-3000 BC) (Seyd Sajjadi, 2005: 31) (Hojabri-Nubari, 2009: 112-125) has been reported in other words, it seems that the Shahryeri complex is a type of cenotaph, or “empty tomb”, “empty tomb”, “tomb of the unknown soldier”. As mentioned in detail in the previous section, in the centuries of AD, anthropomorphic monoliths with different characteristics such as monuments of warriors, heroes and symbols of fertility have emerged in connection with the burial of people. Human statues are mentioned in the texts according to different situations in AD periods with titles such as Dash Baba, Bal Bal and Badiz (Yilmaz, 2003: 45-40). It can be said that Balbal is the stone of the captured soul of the enemy and it is not in good shape, but the deceased himself or his relatives put it on his grave as a memorial stone. In recent centuries, in a wide area in the Near East, stones in the shape of a ram (image 10), a horse (Fig. 11), a turtle (Fig. 12), and in some areas, male (Fig. 13) and female genitals (Fig. 14) were placed on graves as Grave markers are used, which in general seem to be related to fertility symbols Investigations show that in the millennia discussed in this research, no findings have been found on worshiping the dead and making allegories of people and animals with the aim of praying to them. It seems that these anthropomorphic monoliths were generally built to commemorate prominent people and symbols of fertility, and their association with burial sites indicates that this culture was associated with the belief in the world after death. So far, there have been many theories about what this culture is, although it is not far from the mind that these memorial stones were erected in different human societies with religious, promotional and social purposes (Svin, 2005: 89).
But what can be understood from the study of the development of the culture of anthropomorphic monoliths is their relationship with traditions and rituals that are manifested in the form of the embodiment of the deceased person in relation to his burial. It is necessary to explain that this culture has been exhibited in many graves in different societies from the prehistoric period (Agasioglu, 2013) to the recent centuries (Yilmaz, 2003: 44) in the form of different symbols, and in general, their evolution can be seen. From memorial stones to fertility symbols Among the other concepts that are shown on the anthropomorphic monoliths is the ritual of sacrifice. This ritual is shown in the form of animals on the anthropomorphic monoliths of Hakkari and Astara. It seems that the example of humans with smaller dimensions who are unbalanced and fallen on the ground on the edge of the central person to whom the stele belongs are carved on the stele. be an example of human sacrifice.

Conclusion
The main topic of this research is to investigate what and why the anthropomorphic monoliths are erected In this regard, at first, the area of temporal and spatial expansion of this culture was explained In the prehistoric period, this culture generally spread in the geographical area between the Black Sea and the Caspian Sea, and among the most important traditions related to burial during the 3rd, 2nd and 1st millennia BC in the geographical area of northwestern Iran, the Caucasus, and eastern Anatolia has been In recent times, this culture has spread from the western borders of China to Europe In centuries AD, the culture of anthropomorphic monoliths has been mentioned in the texts of poems and archeological findings with different names such as Balbal, Badiz, Dash Baba, etc., which shows many characteristics in the traditions of their beliefs and other In terms of historical and geographical sequence, there is no connection between the culture of anthropomorphic monoliths before history and the beginning of history and AD, or at least it is not known so far. However, the written sources about Balbal and Badiz are among the most important semantic data of this culture. anthropomorphic monoliths culture has been common for several thousand years, from the western borders of China to the Baltic Sea and Spain, and it has been reflected in archeological findings and written sources in the periods after AD. It seems that the most important reason for the temporal expansion of this culture lies in its religious and ritualistic nature, and what caused the spatial expansion of this culture was probably related to commercial exchanges and, as a result, cultural exchanges. anthropomorphic monoliths can be seen over time in human and animal forms and fertility symbols This culture in the mentioned areas, although there are visual differences in some details, but in many cases, they have common features. The level of visual and technical similarities is such that it emphasizes the connection of this culture during the time under investigation in a wide geographical area. So far, there have been many theories about what this culture is in this regard, religious, promotional and social goals were mentioned, but the investigation of the development of anthropomorphic monoliths culture in the context of time and space shows that this culture is related to the burial of traditions and religious rituals. This issue has also appeared in archaeological texts and findings.

Abstract
A series of field activities including two seasons of survey and excavation at the Shahneh Poshte cemetery of Babol on the northern slopes of the Alborz Mountains in central Mazandaran in 2018 and 2019 resulted in the discovery of a collection of human graves and burials scattered throughout this 11-hectare site. Due to the mass of destruction caused by unauthorized excavations in the cemetery, several disturbed graves were observed without any classifiable information. In contrast, by conducting scientific excavations in the 16 trenches, a total of 39 identifiable and Readable human burials were found and then the collection of information and archaeological findings related to each burial was recorded and classified. In this study, we attempt to answer questions about the existence of possible burial methods and patterns and the meaningful characteristics of these variables by studying a set of different aspects including burial practices such as the position and orientation of the body, position of face of hands, architectural structure of the graves, gender and age of skeletons, individual and group burials, and burials with and without objects. The results of absolute dating and comparative studies indicate that this cemetery belongs to a long time span from the 11th and 12th centuries BC (Iron I) to the 4th and 3rd centuries BC, i.e. the Achaemenid to the early Parthian period (Iron IV), and therefore cultural materials of this cemetery are comparable to intra-regional ancient sites in Mazandaran as well as trans-regional sites in the Gorgan Plain, the Central Plateau, and especially the Gilan region. Our research also shows that the Shahneh Poshte graves follow a specific pattern in some burial aspects including the supine position and the direction of the face to the south and therefore have long-term burial traditions.

Introduction
The Shahneh Pashte cemetery is located adjacent to village of Kamikola and southwest of the Khoshrudpey city and 21 kilometers south of the Babol (Fig. 1) (Saedian, 2014: 321). This cemetery was excavated over two seasons in 2018 and 2019 by Hassan Fazeli Nashli. The result of these excavations was the identification of 39 human burials in situ (28 graves) (Fig. 2) which provide a set of valuable archaeological data such as absolute and relative dating, burial methods including the position and orientation of the bodies and faces, the position of the hands and the structure of graves. Based on the whole of archaeological data, the site can be dated to the late 2nd millennium B.C (late Iron I) to the mid-1st millennium B.C (Iron IV, 3rd - 4th centuries B.C / Achaemenid to early Parthian). More precisely, the absolute dating on 5 skeletons uphold this period. Based on archaeological studies between 39 burials, 29 burials belong to the late Iron I (late 2nd millennium BC) to Iron III (burials 1-11 and 22-39) are called “Iron age I - III Group” and the other 10 burials (burials 12-21) can be dated to the 4th and 3rd centuries B.C (late Achaemenid to early Parthian) that are called “Iron age IV Group”, considering the absolute dates of the two burials and their spatial relationship.

Discussion
The study of the Shahneh Poshte burials shows that a set of methods were used to place the deceased in grave which are divided into two general categories: lying on the sides and supine. These two general modes include a total of 11 sub-modes. In general, in the entire Iron Age in this site (I-IV), the lying on the sides includes 13 burials (33.3%) including 4 burials on the right and 9 burials on the left, supine 15 burials (38.5%) and also 11 burials (28.2%) lack any recognizable signs. In more detail, during the Iron I-III period, there were 8 contracted burials (28% of total) of which 4 were on the right and 4 on the left. In addition, 12 burials (41% of total) were buried in supine. Also, 9 burials (31% of total) were of unknown status. In the Iron IV, there were 5 contracted burials (50% of total) all of which were on the left and no right-sided burials were found. Moreover, 3 burials (30% of total) were buried in supine. Finally, 2 burials (20% of period) were classified as undetermined burials due to extensive damages (Fig. 3-5). Regarding the position of the hands of the skeletons, during the Iron I-IV, a total of 16 positions were observed which can be classified into three general groups: lying on the sides, supine and unknown. In addition, the first group includes 6 subgroups (25% of all), the second group is divided into 9 subgroups (54% of all) and the third group is divided into 9 cases (21% of all) as unknown (Fig. 6-7). In Shahneh Poshte, three types of grave architecture have been identified. The first is a simple pit, second is a simple pit with a clay cover and the third is a pithos. Of the 28 graves in site, 26 graves (93% of all) are simple oval pits, of which 20 graves belong to the Iron I-III (71.6%) and 6 graves (21.4%) belong to the Iron IV. The second method, a simple pit covered with big clay fragments includes only 1 is from Iron Age I-III (3.5% of total). Also the pithos burial consists of only 1 grave (3.5% of total) from Iron Age IV (Fig. 8-10). In terms of gender and age of the deceased in this cemetery, total of 9 burials (23% of all) were identified as male, including 8 burials (27.6%) in Iron I-III and 1 burial (10%) in Iron IV. In addition, there were 14 burials (36% of total) as female including 12 burials (27.6%) in Iron I-III and 2 burials (20%) in Iron IV. Also, of the total burials, 16 burials (41% of total) were disturbed (Fig. 11-17). In addition, 7 different positions of the bodies were identified in relation to geographical directions including: south-north 5% of all, east-west 2.5%, west-east 23%, northeast-southwest 10.5% of all, southwest-northeast 10.5%, southeast-northwest 10.5%, northwest-southeast 15% and also an unknown direction 23% of all burials (Fig. 18-19). It is worth noting that for the orientation of face, during all periods, the dominant method was the south direction with a total of 23% of all burials, and especially 20.5% of all in Iron I-III, it was certainly the most common burial method. It seems that this method was not a priority in the Iron IV and was used less often. After that, the north direction was the most common method with 15.3% including 10.2% in Iron IV and 5.1% in Iron I-III (Fig. 20-21). Regarding other study characteristics, 67.8% of the total graves are individual and 32.2% are group graves. Among the first group, 53.5% of the total is related to Iron I-III and 14.6% are related to Iron IV. In addition, group graves comprise 32.2% of the total graves of which 621.5% are related to Iron I-III and 310.5% are related to Iron IV (Fig. 22-25). Finally, about the possession of objects, in total, 70% of all burials were buried with burial objects and 30% did not contain any goods (Fig. 26-27). Finally, regarding the amount of possession of objects, in total, 27 burials (70% of all) were buried with burial objects, and only 12 burials (30% of total) did not contain any burial objects or grave goods.

Discussion 
Human skeletons in Shahneh Poshte cemetery are mostly buried in individual and group graves, including 28 graves which mostly include simple pits, one case of a simple pit with a clay cover and one pithos. In fact, the architectural of the graves was mostly in form of simple pits. A simple pit grave with a clay cover is quite unique in this site and a similar the grave has apparently been found only in one grave in the Lefork cemetery of Savadkuh which has been dated to Iron Age III (Abedini, 2017: 154). Third group of tombs is pithos type that has many similar older and contemporary examples in Mazandaran county. Among the numerous similar examples in the Iron Age of Mazandaran, can mention the children’s tombs in Gohar Tepe (Piller and Mahfroozi, 2009: 19) and cemetery Amirkola in Savadkuh (Abedini, 2017: 154), as well as Qaleh Kuti I cemetery (Fukai and Ikeda, 1971: Pl. XIX, Fig. 2) and Kaluraz in Gilan (Fahimi, 2002: 106-107), Tepe Gyan (Contenau and Girshman, 1935: 12), Maral Tepe of Uzbeki (Majidzadeh, 2008: 135-136) and Dinkhah Tepe (Muscaerella, 1974: 75). In addition, this method reached its peak of use during the Parthian period such as Taq bustan in Kermanshah (Kambakh Fard, 1998: 45), Liarsang-Ben cemetery in Gilan (Jahani et al., 2023: 38; Jahani et al., 2018: 114), and especially in the central Zagros basin (Mohammadi Far and Hojabari Nobari, 2004) such as Sanandaj (Khosravi et al., 2018: 317), Marivan (Mohammadi Far and Sarraf, 2006; Masoumian and Rahimi-Galugahi, 2012: 428) and several points in the city of Hamadan and its surrounding areas (Azarnoush, 1975: 56, vol. 7; Dailer et al., 2013). The graves of Shahneh Poshte are scattered in different parts of the cemetery and it does not seem that a specific space of the cemetery was dedicated to a specific group or class of people in this society. The group graves are in the form of two-burial and three-burial graves with a slight difference in depth and space compared to each other, although the attribution of some of these group burials to each other has been ambiguous. However, the spatial proximity of the skeletons and their burial objects and the difficulty in distinguishing them from each other led to the attribution of some of them to a single grave and it seems that even despite a slight difference in depth, there was a clear awareness in creating a single grave for multiple skeletons. Usually, the deceased were placed in the grave in various positions, either contracted (lying on their sides) or supine with different positions inclined to the right or left. The positions of the hands are usually in front of the chest and face and sometimes in line with the body and the legs are also bent in three different degrees: less than a 90-degree angle (high, inclined inward towards the abdomen and spine: grade 1), 90-degree angle (medium, perpendicular angle to the spine: grade 2), and more than 90-degree angle (low, open angle to the spine: grade 3). A few are also supine and extended in line with the body.

Conclusion
The study of the burials of the Shahneh Poshte cemetery shows that there were a group of methods and rituals related to the burial of the dead, some of which were used more than others and, in other words, became a burial tradition. Regarding the position of the dead during the Iron Age and during the use of this cemetery, all the conventional methods of placing the deceased in the grave were used in the Shahneh Poshte area and despite the slightly higher number of supine method, it does not have a significant advantage over the lying on sides method and both methods can be seen as burial methods and traditions in great abundance. Also, the supine method was the most common burial method among women with 71% and men did not have any dominant method. In the discussion of the architectural structure of the tomb, the common tradition and method, the usual method is a simple oval pit but there are two unique methods, one is a simple pit grave covered with pottery fragments and the other is a pithos burial, each of which was used in the form of a grave only as a specific method, not a burial tradition. Finally, based on the set of burial characteristics of the Shahneh Poshte cemetery, it can be seen that this site is comparable in many aspects to sites within the region in Mazandaran and adjacent the region especially Gilan and the Central Plateau. It can also be considered that the set of burial methods and traditions of the Shahneh Poshte cemetery is homogeneous and identical to other contemporary sites in Mazandaran and to some extent a continuation of some pre-Iron Age burial methods in this region.
