In the main arch at Taq-e Bostan, the bas relief of the imperial deer hunt is in poor condition when compared to the Boar Hunt on the right
Nevertheless, interesting aspects are portrayed:

Riders hunting deer that have been rounded up by beaters.
Khosrow II beneath the imperial umbrella attended by musicians.
Camels taking away the bounty.

These pictures have been enhanced and also corrected for perspective distortions.
