Shapur I's victory relief at Naqsh-e Rostam

Shapur I's inscription at Naqsh-e Rostam is located 3 kilometers away from the north of Takht-e Jamshid. This is probably the most famous inscription dating from Sasanian Persia. This inscription depicts a famous scene in which the Roman Emperor, Valerian, is kneeled before Shapur I and asking for grace. Shapur defeated Valerian at the Battle of Edessa, in which the entire Roman army was destroyed and Valerian itself became Shapour's prisoner. This was the first and the only time a Roman emperor taken as prisoner. There's a Greek inscription that has 5 lines in the bottom of the horse, but it is damaged. It is believed that there was two inscriptions in Middle Persian and Parthian language as well, but were destroyed.
