and Herodian's works, can be understood. He believes that the Sasanians' territorial claims were basically different from those of the Achaemenids. In the Sasanians' legendary genealogy that has appeared in Kar-Namag i Ardashir i Pabagan, the relation between the Sasanians and the Achaemenids is mentioned. In the book, the thought that has been reflected is the relation of Sasan, the ancestor of the Sasanian house, with Darius's descendants on one hand and the local Persian kings on the other hand; though in the fifth century, the Sasanians attributed their lineage to the mythical kings of Avesta or Kayanians; and its proof is the addition of the prefix "Kay" to the aliases of the Sasanian shahanshahs. The question whether those claims and schemes and avengings, in the same way as mentioned in the historical sources, were actually proposed by Ardashir himself or were later attributed to him as the founder of the empire has still remained without answer due to the lack of sufficient sources; though the attribution of these claims to Ardashir after his lifetime seems more logical. According to these, it is undoubtedly true that Ardashir's grandiose views about policy and relations with the outside world had formed based on rebooting and repeating the Achaemenids' successes. However, the Sasanians' knowledge of the Achaemenids were superficial and vague information and did not have a regular and historical basis. About that, Richard Frye and Daryee believe that the section of the Arabic-Persian sources (like Al-Tabari) that contain the Sasanian history since the beginning until the age of Khosrow I should be looked at suspiciously; they consider this suspicious look at texts like Kar-Namag i Ardashir i Pabagan too. The suspicious look has been due to that most of the Iranian history sources were edited in the age of Khosrow I and by the royal writers and clerics in order to accommodate their predecessors' history with then world view of the Sasanian empire and draw a picture of Ardashir idealistic and aligning with Khosrow's ideals in the best way. Religious policy Papak was the grand priest of the temple of Anahita in Istakhr and the father of Ardashir, the founder of the Sasanian house, with the beginning of whose reign religion sat on the Persian throne. Papak's religious credit might have helped him in taking the power from Gochihr, then Persian governor who had no interest in following the religion of fire.
