The two equestrian reliefs of Bahram II (c. 276-293).
This equestrian relief, located immediately below the tomb of Darius I, is divided into two registers, an upper and a lower one.
In the upper register, the king appears to be forcing a Roman enemy from his horse.
In the lower register, the king is again battling a mounted Roman soldier.
Both reliefs depict a dead enemy under the hooves of the king's horse.
Next to Bahram, his standard bearer is visible.

Bahram II was the fifth Sasanian King of Persia in 274–293. He was the son of king Bahram I and the grandson of king Shapur I.

He was not the strongest ruler of the Sasanian dynasty. Having lost a war against the Roman emperor Carus, he accepted the loss of Armenia and Mesopotamia; he had some difficulty in suppressing a revolt by his brother Hormizd II; and he lost power to the Zoroastrian high priest Kartir.
Still, Bahram II left no less than ten rock reliefs, three of them in Naqsh-e Rostam.
