https://en.wikipedia.org/wiki/Charon

"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"
