Abstract
Up to now, 35 rock reliefs have been identified from the Sassanid period, one of them is located outside the political borders of Iran, at the site known as the Rag-e Bibi in Afghanistan. 34 other rock reliefs have been discovered inside Iran’s political borders in various regions such as: Rey city, Taq-e Bustan, Salmas, Barm-e Delak, Goyum, Tang-e chogan of Bishapour, Naqsh-e Rostam, Naqsh-e Rajab, Sarab-e Bahram, Tangab-e Firouzabad, Darabgerd, Tang-e Qandil and Sar Mashhad. Although all of these rock reliefs were studied by archaeologists and domestic and foreign researchers repeatedly, but most studies have focused on identifying the main character of the rock reliefs -the Sassanid king. And there is no serious and diligent attempt at identifying other characters on the scene. Of course, some scholars tried to clarify the true identity of some of the characters in the Sasanian rock reliefs. But most of them did not succeed. Because most of these identities are based on speculation. However, identifying individuals in the Sasanian rock reliefs should be based on historical evidence or face recognition or semiotic studies. For example, some researchers said that the character discussed in this article should be the servant of the king. Some also said that he should be the representative of the Karin family. In this research, which is based on the purpose of basic research and based on the nature and method of historical research, was attempted to clarify the true identity of one of the characters in the rock reliefs of Ardashir Babakan with the help of historical evidence, face recognition and semiotic studies. The results of the studies show that the person present in the rock reliefs of Ardashir Babakan should be Tansar. An influential clergyman who has been tried to spread Zoroastrianism and to regulate the texts of Avesta, and helped Ardashir Babakan to reach power and also helped him stabilize his power.

Introduction
Personology of Sassanid reliefs raised debates among researchers, because of same thematic models of Sassanid kings and lack of inscriptions. Present paper discusses Ardashir’s relief of investiture and crowned by Ahuramazda. 
The research is based on the purpose of basic research and based on the nature and method of historical research, whereas collected data bibliographically, identification and thorough study of different written historical sources, and fieldwork, visiting Ardashir’s reliefs at Tanganb Firuzabad, Naqsh-i-Rajab and Naqsh-i-Rostam. Comparative study of historical sources and analytical approach at archaeological evidences and using historical approache are the methods to analyze and interpret data. 

Visual Evidence and Semiotics
Sassanid martial activities initiated years earlier that Ardashir to overcome Persia. Different factors caused clergymen raised to power and became influential through Sassanid rule (Hosseini 1392). Ardashir Babakan was a priest of Anahita temple at Istakhr, Fars (Christensen 1367: 134) enjoyed and joined dissatisfied clergymen to his government and endowed them high positions; it was his philosophy because his new ruling based on religious power and aristocracy that concluded to unification of religion and ruling (Hosseini 1392). As conclusion, one can say Ardashir needed clergymen confirm him to legitimize his ruling. Direct relation and superiority on people, doubled acceptance and support of clergymen. Following study of historic and written sources on presence of a cleric figure alongside Ardashir, firstly there is need to involve in similar visual parameters of the relief, which is identified earlier, for personological studies of the figure. In order to conclude, figure of Kartir is the best option, among options, because of the similarities to target figure, on the other hand, we know Kartir for the badge on his hat (Moosavi Haji 13996: 166); powerful face with shaved face, a badged hat, and his hair that came out of his hat on neck (fig. 5). His official custom is a long robe to his knee and a belt with a sheath (fig. 6). All explanation about his appearance is comparable to our target figure, so one could suggest that the appearance characteristic of Sassanid clergymen relied on the same pattern and tradition. However, every clergyman has common characteristic in every given religion. 

Conclusion 
Accordingly, one could conclude:
- It is not logical that a neutral person, a servant, would be carved on a public media such as a royal relief, let alone in a scene of investiture ceremony and crowning of Ardashir as the representative of Ahuramazda on earth. 
- No servant allowed to hold sword.
- Accordingly, Ardashir always needed general legitimation and acceptance that could be facilitated by a chosen religious figure at people. 
- Considering Sassanid and further written and historical sources, presence of Tansar as great supporter and evangelist is undeniable. His appearance in the relief matches to the discussion of present paper. 
- Visual composition and evidences of the figure, garment, shaven face, hat, and hairs are completely similar to great clergyman Kartir of later Sassanid period, so one could probably suggest it as general homogeny of the clothing of clerics during Sassanid period. 
- Badge of the figure, is completely similar to Kartir’s badge, on the other hand, adaptable to fire altar of reverse of coins of Persid period. Persids ruled Fars province during Seleucid and Parthian eras, who were eager to religious issues, so some scholars name them “fire servants”. 
- The target figure is present at Sassanid sources and religious events of Ardashir reign, but according written sources, Kartir replaced him after this period with no further trace on reliefs. 

Abstract
With the foundation of Sasanian dynasty, the first fully anthropomorphic representations of Ohrmazd appeared in ancient Iranian art. He was depicted in eight rock reliefs at Firuzabad, Naqsh-i Rajab (2 scenes), Naqsh-i Rustam, Tang-i Chugan (2 scenes) and Taq-i Bustan (2 scenes) while investing a beribboned diadem to the Sasanian king. The iconography of Ohrmazd was not a new one and before Sasanian period in Commagene and Bactria, the image of Ohrmazd had mainly created by imitating Greek-Roman prototypes. But the iconography of Ohrmazd in Sasanian rock reliefs was different. He was completely depicted in Iranian artistic fashion, and in some scenes, he carried bundles of barsam. Barsam is an implement carry by priests in ceremonial rituals. However, Avesta reveals that barsam was not only use by priests, but also hold by some deities including Ohrmazd. In Aban Yasht, Ahura Mazda (Middle Persian Ohrmazd) praises Aredvi Sura Anahita with the barsam. There are still questions about the figure of Ohrmazd and the sources of his iconography in Sasanian rock reliefs. So it is significant to review Zoroastrian texts again and study whether they affect the iconography of Ohrmazd or not. By analyzing and comparing the characteristics and details of iconographical elements of Sasanian rock reliefs and also regarding Zoroastrian written sources, the authors try to find the origin of these artistic models and the reason why Ohrmazd carries a bundle of Barsam at Firuzabad, Naqsh-i Rajab, Naqsh-i Rustam and Taq-i Bustan investiture scenes. The results show that the iconography of Ohrmazd was especially modeled after the royal art and the king himself. Furthermore, Some Zoroastrian texts reveal that Ohrmazd incarnate in Gētīg (material world) as an Ahlaw man or a priest and probably Sasanian artists consciously depicting him while carrying barsam in his hand(s).

Introduction
By defeating the last Parthian king, Ardavan V, Artaxerxes I (224-240/1 CE) established an empire which was concentrated on centralization of Iranian state and unification of religion. To unify religion (Zoroastrianism), the iconoclastic movement was formed by Artaxerxes I. According to ancient sources, Artaxerxes I ordered to destroy idols, and instead many fires established throughout the empire; even some pre-Sasanian sacred fires were replaced by new ones. However, it seems such strictness does not prevent creating images of divine beings. There are evidences of iconography of Zoroastrian deities in Sasanian art. An important point is that in the Avesta and the Middle Persian texts, some deities were incarnated in human or animal forms and so the religious texts may be good sources for representations of deities. Interestingly archaeological evidence and written sources revealed different version of Zoroastrian in Armenia and Central Asian and idol-worship customs were prevalent there. In Commagene and Bactria, the image of Ohrmazd was mostly depicted according to Greek-Roman prototypes. On the contrary, the image of Ohrmazd as the superior Zoroastrian deity in Sasanian art was different and imitated from Iranian models. At Naqsh-i Rustam, the definite image of Ohrmazd contribute identification of him in other Sasanian rock reliefs. Due to the inscription, it was the only certain known evidence of Ohrmazd in Iranian art. At the same time, it is regarded as a significant document of the iconography of Zoroastrian divinities from the early Sasanian period. Despite extensive and diverse studies on Sasanian art and representations of Zoroastrian deities, including Ohrmazd, there are still ambiguities about the iconography of Ohrmazd and the sources of his visual images, the contribution of religious texts, and the influence of other iconographies of Ohrmazd on his representations in Sasanian art.

Discussion
Archaeological evidence and written sources shows that Ohrmazd occupied the highest status in ancient Iranian beliefs. The oldest and most definite references to him traced back on Achaemenian inscriptions (Lecoq, 1997: 176-276) and fortress tablets at Persepolis (Henkelman, 2008: 527-529). Furthermore, some scholars regarded the images of the winged disk with or without a bearded bust on Achaemenian monuments as the very ancient image of Ohrmazd (Lecoq, 1984; Skjærvø, 2014: 179-180). Contemporary with Parthian at about 30 BC, the Commagene king, Antiochus I erected statues of gods at Nemrud Daq (Herzfeld, 1941: 275). According to the inscriptions, one of the statues belongs to Oromasdes who was synchronized with Zeus (Widengren, 1986). Although he dressed in Persian fashion (Duchesne-Guillemin, 1978: 189) and holding barsam, but he was depicted like Zeus. On Kushanian coins, Ohrmazd was depicted again more likely after Greek models (Shenkar, 2014: 61-62), but under the name of Ōoromozdo or the abbreviated name Ōrom (Humbach, 1975: 139-140). For the first time during Sasanian period, Ohrmazd was represented in a fully anthropomorphic figure while investing a diadem to the Sasanian kings. At Naqsh-i Rustam, Ohrmazd synchronized with Zeus (Lukonin, 2005: 307), but he was depicted completely different and he appeared resemble to Sasanian kings probably for legitimization goals. Furthermore, Ohrmazd holding barsam in several reliefs. According to Bundahišn, Shāyist Nāshāyist, Ohrmazd incarnated as an Ahlaw man or a priest (Zot or Atravan) in Gētīg. He also praised Aredvi-sura-Anahita with barsam (Yš. 5. 17). So it seems that Sasanian artists deliberately depicted barsam in the hand of Ohrmazd to show him in the figure of Zoroastrian priest. As the image of Ohrmazd was not remained similar during Sasanian period, barsam appeared on Artaxerxes I’s rock reliefs and reemerge on Khosrow Parviz’s investiture at Taq-i Bustan.

Conclusion
Before Sasanian period, no definite representation of Ohrmazd is detected in Iran. The only images of the winged disk on Achaemenian and post-Achaemenian monuments in Pars attributed to Ohrmazd by some scholars. Contrary to Parthians, the iconography of deities in Sasanian period is much fewer. Although ancient sources attribute iconoclast movement to Artaxerxes I, but archaeological evidence manifest production of divine images. However it is important to distinguish cultic statues and portrayal of deities in the art. During Sasanian period fire-temples were established all over the kingdom and the cult of fire become the state religion. Erecting cultic statues was prohibited, however the images of deities including Ohrmazd produced in Sasanian art. Investiture ceremonies on rock reliefs show Ohrmazd in the shape of a royal figure while in some cases carrying a barsam like Zoroastrian priests. As Sasanian kings emphasize their legitimate claim during their sovereign, Ohrmazd depicted similar to the king. The representation of Ohrmazd in these monuments was completely in Persian mode and was against the image of him in Commagene or Kushan where he was depicted after Zeus. In the Middle Persian texts, Ohrmazd is invisible even amongst the sacred beings, except for the prophet Zardosht. He can be comprehend through wisdom and the power of comparison. However in the Pahlavi Rivāyat and Shāyist Nāshāyist, Ohrmazd described with a human appearance. In a passage from Shāyist Nāshāyist, Ohrmazd is an intangible spirits who appears in Gētīg in the body of the Mard-i Ahlaw (Just man). According to Bundahišn, Ohrmazd appears in the form of Zoroastrian priest in Gētīg. Also, he comes to the world as Zot. He is Atravan. So it is not strange that Ohrmazd depicted as a priest in some reliefs, while carrying a barsam. 

Sasanian Empire was one of the most powerful periods in ancient Iran. Archaeological evidence and traces, and Sasanian and Post-Sasanian texts show cultural and artistic relations of the Sasanian Empire from the East to the West. However, official Sasanian methods of warfare are one of the most important legacies of the period that have been less studied. These offensive and defensive arms and armor can be analyzed by looking at remaining evidence left by kings and officials within the national borders to the lands abroad. Sasanian swords are depicted on rock reliefs, silver dishes, and coins (drachmas and dinars). Although studies have been done on the classification of Sasanian swords shown on rock reliefs, no systematic study on the depiction of Sasanian swords on Sasanian drachms has been done so far. The following paper tries to restudy the subject by comparing the swords depicted on Sasanian coins and compare them to the swords shown on rock reliefs and dishes. Sasanian swords are depicted on different Sasanian royal arts such as Sasanian coins, Sasanian silver dishes, and Sasanian rock reliefs. Different elements will be taken into consideration such as the shape of swords in general and their method of hanging from the belt in particular. A closer look shows that Sasanian drachmas and dinars show two major types of hanging Sasanian swords via a scabbard slide system: A. hanging the sword in front of the body. B. hanging the sword on the left or the right hip. Additionally, the following paper will compare them to some extant examples of Sasanian swords that are kept in museums and private collections.
