The dynasties of the Parthians and Sasanians ruled over Iran, Iraq and much of Central Asia and Afghanistan from 248 B.C. - 651 A.D. Both the Parthians and the Sasanians used images on their coins that underline the close connection with God claimed by the kings. Kings were seen as God's representatives on earth. For example, the Parthian 'King of kings' often receives a royal headband (diadem) or palm frond as symbol of kingship from a goddess.
