A third-millennium BC earthen goblet discovered at the Burnt City, a Bronze Age urban settlement in southeastern Iran, depicts what could possibly be the world's oldest example of animation. The artifact, associated with Jiroft, bears five sequential images depicting a wild goat jumping up to eat the leaves of a tree. The earliest attested Iranian examples of visual representations, however, are traced back to the bas-reliefs of Persepolis, the ritual center of the Achaemenid Empire. The figures at Persepolis remain bound by the rules of grammar and syntax of visual language. The Iranian visual arts reached a pinnacle by the Sasanian era, and several works from this period have been found to articulate movements and actions in a highly sophisticated manner. It is even possible to see a progenitor of the cinematic close-up shot in one of these works of art, which shows a wounded wild pig escaping from the hunting ground.
