However, Eteocles refused to cede his throne after his year as king. Polynices brought in an army to oust Eteocles from his position and a battle ensued. At the end of the battle the brothers killed each other after which Jocasta's brother, Creon, took the throne. He decided that Polynices was a "traitor," and should not be given burial rites. Defying this edict, Antigone attempted to bury her brother. In Sophocles' "Antigone", Creon had her buried in a rock cavern for defying him, whereupon she hanged herself. However, in Euripides' lost version of the story, it appears that Antigone survives. Most, if not all, of our knowledge of Oedipus come from the 5th century BC. Though these stories principally deal with his downfall, various details still appear on how Oedipus rose to power. King Laius of Thebes hears of a prophecy that his infant son will one day kill him. He pierces Oedipus' feet and leaves him out to die, but a shepherd finds him and carries him away. Years later, Oedipus, not knowing he was adopted, leaves home in fear of the same prophecy that he will kill his father and marry his mother. Laius journeys out to seek a solution to the Sphinx's mysterious riddle. As prophesied, Oedipus and Laius cross paths, but they do not recognize each other. A fight ensues, and Oedipus kills Laius and most of his guards. Oedipus goes on to defeat the Sphinx by solving a riddle to become king. He marries the widowed Queen Jocasta, unaware that she is his mother. A plague falls on the people of Thebes. Upon discovering the truth, Oedipus blinds himself, and Jocasta hangs herself. After Oedipus is no longer king, Oedipus's brother-sons kill each other. Some differences with older stories emerge. The curse of Oedipus' sons was elaborated on retroactively to include Oedipus and his father, Laius. Oedipus now steps down from the throne instead of dying in battle. Additionally, rather than his children being by a second wife, Oedipus's children are now by Jocasta (hence, they are his brothers as well).
