In order to remark his victories, Ardashir carved petroglyphs in Firuzabad (the city of Gor or Ardashir-Khwarrah), Naqsh-e Rajab and Naqsh-e Rustam. In his petroglyph in Naqsh-e Rustam, Ardashir and Ahura Mazda are opposite to each other on horsebacks and the corpses of Artabanus and Ahriman are visualized under the hooves of the horses of Ardashir and Ahura Mazda. It can be deduced from the picture that Ardashir assumed or wished for others to assume that his rule over the land that was called "Iran" in the inscriptions was designated by the lord. The word "Iran" was previously used in "Avesta" and as "the name of the mythical land of the Aryans". In Ardashir's period, the title "Iran" was chosen for the region under the Sasanian rule. The idea of "Iran" was accepted for both the Zoroastrian and non-Zoroastrian societies in the whole kingdom and the Iranians' collective memory continued and lived on in the various stages and different layers of the Iranian society until the modern period today. What is clear is that the concept of "Iran" previously had a religious and ethnic application and then ended up creating its political face and the concept of a geographical collection of lands.
