What are the names of the four children of Oedipus?

I'm assuming that you're asking about the children of the mythical king of Thebes, Oedipus, who is the subject of Sophocles' three Theban plays. Oedipus, who was given up at birth by his father, Laius, the then King of Thebes, because it was prophesied that his child would kill him, unwittingly fulfills the prophecy by killing his birth father and marrying his mother, Jocasta, with whom he has four children — Antigone, Ismene, Eteocles, and Polynices. The first two are girls the second two are boys. They are, of course, also his half-siblings although he doesn't learn this until much later. A fight between Eteocles and Polynices later results in a civil war. Antigone is later buried alive by King Creon.
