“A shadowy figure from ancient Greek mythology, Charon, ferries the souls of the dead over the River Styx (alternatively the Acheron) to the Underworld. A coin was placed on the tongue of the deceased to pay for safe passage, without it the soul (or “shade”) may be lost to wander the realm for at least one hundred years.”
