In Greek mythology, Charon was the son of Erebus and Nyx. He was the ferryman who transported the dead across the river Styx to the Underworld of Hades. Charon was depicted as a squalid, mean, sprightly, bad tempered old man. Charon demanded a fee of an Obol for the journey across the river Styx, and to this end the Greeks buried their dead with an Obol coin in their mouth with which to pay Charon. Hercules forced Charon to ferry him into the Underworld, and Hades punished Charon by binding him in chains for a year. Research Charon
