The earliest recorded representations of dancing figures within Iran were found in prehistoric sites such as Tepe Sialk and Tepe Mūsīān. The oldest Iranian initiation of theater and the phenomena of acting can be traced in the ancient epic ceremonial theaters such as ''Sug-e Siāvuš'' ("mourning of Siāvaš"), as well as dances and theater narrations of Iranian mythological tales reported by Herodotus and Xenophon.
