Oedipus

The great masterpiece on which Aristotle based his aesthetic theory of drama in the Poetics and from which Freud derived the Oedipus complex. King Oedipus puts out a sentence on the unknown murderer of his father Laius. By a gradual unfolding of incidents, Oedipus learns that he was the assassin and that Jocasta, his wife, is also his mother.
