Persian armoured cavalry in the
Sassanid Rock Relief at Fīrūzābād
Drawing of the 1st relief at Firuzabad
On the first scene, a Persian seizes his Parthian opponent and has his arm around his enemy.
This scene, in the centre, shows how Ardašir's son Shapur unseats Artabanus' vizier. Note the fine armour of the rider and the horse.

Finally, the fight between the two kings: Ardašir defeats Artabanus, whose horse turns a somersault. The victorious new king attributed his success to the god Ahuramazda, which is the subject of the second relief.
The relief shows three stages in Ardašir's fight against the Parthian king Artabanus V in 224.
The Persian leader, who had united the southern part of modern Iran, had built Ardašir Khureh, and Artabanus was worried about Ardašir's increasing power.
When he arrived with an army, however, he was defeated by his rebellious vassal and the Persian became the new "king of kings".
This was the beginning of the rule of the Sasanians, which was to last until the rise of Islam in the seventh century.
