The "Thebaid" begins with a view of Oedipus, the former king of Thebes. Having gouged out his own eyes, he had relinquished his kingdom after learning that he had killed his father Laius and committed incest with his mother Jocasta. He places a curse on his sons, Eteocles and Polynices, who had tuned on him because of his transgressions. The fury Tisiphone is sent to Thebes in order to sow discord among the brothers. In the city, Eteocles and Polynices strike a pact, stipulating that rule of the city would alternate between them on an annual basis while the other spent a year in exile. Eteocles is granted the first term as king.
