CHARON

In Greek mythology, Charon is a psychopomp, the ferryman of Hades who carries souls of the newly deceased who had received the rites of burial, across the river Acheron (or in some later accounts, across the river Styx) that divided the world of the living from the world of the dead. A coin to pay Charon for passage, usually an obolus or danake, was sometimes placed in or on the mouth of a dead person. Some authors say that those who could not pay the fee, or those whose bodies were left unburied, had to wander the shores for one hundred years, until they were allowed to cross the river.
