Charon’s Staircase

In the time of Hiero II, an underground corridor was built which crossed the entire orchestra of the theatre.
The recess was accessed by a ladder that led from the stage to a small room: this set-up was identified as Charon’s Staircase.
The name of this scenic device immediately provides a clue as to its function: Charon, in Greek religion, transported souls to Hades along the river Acheron. It is no coincidence then that this passage was used to suddenly appear and disappear by people who played spirits from beyond the grave during theatrical performances.
