The earliest examples of visual representations in persian history may be traced back to the bas-reliefs in Persepolis (c. 500 B. C.). Bas relief is a method of sculpting which entails carving or etching away the surface of a flat piece of stone or metal.Persepolis was the ritual center of the ancient kingdom of Achaemenids and “the figures at Persepolis remain bound by the rules of grammar and syntax of visual language.”
