Nagshe Rajab is located 3 kilometers to the north of Persepolis at the foot of Mt. Hosain (Kooh-e Rahmat), There are carvings of Ardeshir Babakan and Shapur I. This carving consists of three embossed pictures of Ardashir Babakan (r. 226-241 CE), his son and successor Shapur I (r. 241-272 CE), as well as the emblem of his dynasty besides other great personalities of Ardashir’s era.
Naqsh-e Rajab is the site of four limestone rockface inscriptions and rock-cut bas-reliefs that date to the early Sassanid era: One of the carvings is the investiture inscription of Ardeshir I, the founder of the dynasty.

The king recieves the Farr diadem of Power – the two rear figures at left are most likely high-ranking nobles of Wuzurgan (and/or possibly high-ranking military leaders of the Sassanian Spah [army]). The figure to the left bestowing the Farr to Ardashir is most likely the supreme god, Ahura-Mazda.
The second investiture inscription is Ardashir’s successor, Shapur I (241-272 CE).
