Tiresias and Thebes
Tiresias appears as the name of a recurring character in several stories and Greek tragedies concerning the legendary history of Thebes. In The Bacchae, by Euripides, Tiresias appears with Cadmus, the founder and first king of Thebes, to warn the current king Pentheus against denouncing Dionysus as a god. Along with Cadmus, he dresses in women's clothing to go up the mountain to worship Dionysus with the Theban women.
In Sophocles' Oedipus the King, Oedipus, the king of Thebes, calls upon Tiresias to aid in the investigation of the killing of the previous king Laius. At first, Tiresias refuses to give a direct answer and instead hints that the killer is someone Oedipus really does not wish to find. However, after being provoked to anger by Oedipus' accusation first that he has no foresight and then that Tiresias had had a hand in the murder, he reveals that in fact it was Oedipus himself who had (unwittingly) committed the crime. Outraged, Oedipus throws him out of the palace, but then afterwards realizes the truth.
Oedipus had handed over the rule of Thebes to his sons Eteocles and Polynices but Eteocles refused to share the throne with his brother. Aeschylus' Seven Against Thebes recounts the story of the war which followed. In it, Eteocles and Polynices kill each other, and Megareus kills himself because of Tiresias' prophecy that a voluntary death from a Theban would save the city.
Tiresias also appears in Sophocles' Antigone. Creon, now king of Thebes, refuses to allow Polynices to be buried. His niece, Antigone, defies the order and is caught; Creon decrees that she is to be buried alive. The gods express their disapproval of Creon's decision through Tiresias, who tells Creon 'the city is sick through your fault.' However, Antigone has already hanged herself rather than be buried alive. When Creon arrives at the tomb where she is to be interred, his son, Haemon who was betrothed to Antigone, attacks Creon and then kills himself. When Creon's wife, Eurydice, is informed of her son and Antigone's deaths, she too takes her own life.
Tiresias and his prophecy are also involved in the story of the Epigoni.
