Laius, the king of Thebes, received a terrible prophecy from the oracle. He ordered that his infant son be abandoned on a mountain to die. However, the child was given to a shepherd by a servant. Years later, after Laius's death, the man Oedipus unknowingly fulfilled the prophecy by killing his father and marrying his mother Jocasta. Sigmund Freud would later name this concept the Oedipus complex.
