 The investigating archaeologists did not regard the practice as typical of the region, but speculate that the local geography lent itself to adapting the Greek myth, as bodies of the dead in actuality had to be ferried across a river from the town to the cemetery.Charon's obol is usually regarded as Hellenic, and a single coin in burials is often taken as a mark of Hellenization, but the practice may be independent of Greek influence in some regions.The placing of a coin in the mouth of the deceased is found also during Parthian and Sasanian times in what is now Iran.
