Ahura Mazda and Ardashir I is a rock relief from Sasanian Persia.
It is located in the east corner of Naqsh-e Rostam and was carved 2 meters above the ground.
The inscription shows Ardashir I's coronation ceremony in which he receives his kingship seal from Ahura Mazda (or Hormozd) and Ahura Mazda appoints him as the Shahanshah of Ērānshahr.
The man behind Ahuramazda on the left side of the relief is the high priest Kartir.
There's an inscription on Ardashir's horse in three languages: Middle Persian, Parthian and Greek.
