Also:
Oedipus killed King Laius at a place "where three roads meet," or a triple crossroad. Typically, crossroads symbolize a choice to be made. Yet because the murder of Laius occurred in the distant past. Oedipus's choice has already been made, and so the triple crossroads becomes a symbol not of choice but of fate.
