Oedipus King of Thebes

When the play opens, Thebes is suffering a plague which leaves its fields and women barren. Oedipus, the king of Thebes, has sent his brother-in-law, Creon, to the house of Apollo to ask the oracle how to end the plague. Creon returns, bearing good news: once the killer of the previous king, Laius, is found, Thebes will be cured of the plague (Laius was Jocasta's husband before she married Oedipus). Hearing this, Oedipus swears he will find the murderer and banish him. The Chorus (representing the people of Thebes) suggests that Oedipus consult Teiresias, the blind prophet. Oedipus tells them that he has already sent for Teiresias. When Teiresias arrives, he seems reluctant to answer Oedipus's questions, warning him that he does not want to know the answers. Oedipus threatens him with death, and finally Teiresias tells him that Oedipus himself is the killer, and that his marriage is a sinful union. Oedipus takes this as an insult and jumps to the conclusion that Creon paid Teiresias to say these things. Furious, Oedipus dismisses him, and Teiresias goes, repeating as he does, that Laius's killer is right here before him - a man who is his father's killer and his mother's husband, a man who came seeing but will leave in blindness.
