Oedipus the King
Homer's "Odyssey" (XI.271ff.) contains the earliest account of the Oedipus myth when Odysseus encounters Jocasta (named Epicaste) in the underworld. Homer briefly summarises the story of Oedipus, including the incest, patricide, and Jocasta's subsequent suicide. However, in the Homeric version, Oedipus remains King of Thebes after the revelation and neither blinds himself, nor is sent into exile. In particular, it is said that the gods made the matter of his paternity known, whilst in "Oedipus the King", Oedipus very much discovers the truth himself.
