The Oedipus Cycle is a trilogy of Ancient Greek tragedies by Sophocles. In Oedipus Rex, Oedipus tries to escape from a prophecy that he will kill his father and marry his mother. He kills a man (unknowingly his father) and marries the queen, his mother. In Oedipus at Colonus, Oedipus dies and his sons begin to fight. In Antigone, Oedipus' daughter, Antigone, is sentenced to death by Creon for burying her traitorous brother inside the city. Before Creon can rethink his decision, Antigone commits suicide.
