themselves "Frataraka", which probably meant "governor" based on its synonym achieved from the Aramaic documents of the Achaemenid era. Afterwards, the titles of local governors altered and they named themselves "Shahs". There have been royal crowns and symbols, temple pictures, fireboxes with aflame fires, and symbols of the moon, stars and the portrait of Ahura Mazda minted on coins of the Frataraka that shows the holy fire was adored and the Zoroastrian gods were worshiped and the old creed was permanent in Pars in contrast to other regions. In a portrait of Papak and his son Shapur carved on Takht-e Jamshid, Papak, while dressed as a priest, squeezes the hilt of his sword by one hand and manipulates the fire of the hearth and adds more firewood to it by the other hand, with his son Shapur taking the royal ring from him. In other pictures of granting the royal medal during the time, meaning granting Khwasak, the mayor of Susa, which is discovered there, and the picture of granting the medal to the governor of Elymais, discovered in Bardneshandeh, the Parthian emperor is granting the royal medal to local shahs; while in the mentioned picture of Papak and his son Shapur in Takht-e Jamshid, it is Papak who is granting the royal ring to Shapur wearing like priests. Lokonin believed that the carving of Papak granting the royal medal to his sone shows that the Sasanians took the power by force in Pars and wished to show their independence from the Parthian emperors; that was why Papak personally grants the royal medal to his son in the mentioned picture. Lokonin also believes that the religious clothes and medals of Papak on the pictures and cois of Shapur (his son), show the separation of religious and royal rule -at the time; Papak was the grand priest and his son Shapur was the land's shah. Daryaee believes that the picture shows multiple things; first that the House of Sasan had both the religious and irreligious powers together in Pars; second that the fire creed, related to Zoroastrianism, lived on before the rise of Ardashir; third that the carved picture of Shapur and Papak in Takht-e Jamshid shows the importance of the Achaemenid structure for the Sasanians.
