<P> In Greek mythology, Charon or Kharon (/ ˈkɛərɒn, - ən /; Greek Χάρων) is the ferryman of Hades who carries souls of the newly deceased across the rivers Styx and Acheron 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 . In the catabasis mytheme, heroes--such as Aeneas, Dionysus, Heracles, Hermes, Odysseus, Orpheus, Pirithous, Psyche, Theseus and Sisyphus--journey to the underworld and return, still alive, conveyed by the boat of Charon . </P> <P> Charon is the son of Erebus . He was also the brother of, among many others, Thanatos and Hypnos . </P>
