Sasan's family became the rulers of the second Persian Empire and ruled over a great portion of western Asia (the first Persian Empire having been ruled by the dynasty of Cyrus the Great). The three founders of this new empire – that is, Papak and his two sons – are depicted and mentioned on the wall of the harem of Xerxes at Persepolis, a remnant site of the Achaemenids, a representation suggested to be the evidence of a claim to Achaemenid heritage likely later added.
