This tableau carved into the rock face of the cliff is the most famous of the Sassanid rock reliefs. It depicts the Triumph of Shapur I (241-272 CE)) over two Roman emperors, Valerian and Philip the Arab. Behind the king stands Kirtir, (‘high priest’), the most powerful of the Zoroastrian Magi during the history of Iran.
In an inscription, Shapur I claims possession of the territory of the Kushans as far as “Purushapura” (modern day Peshawar) .
