Seven Against Thebes
Queen Jocasta's brother, Creon, had announced that any man who could rid the city of the Sphinx would be made king of Thebes, and given the recently widowed Queen Jocasta's hand in marriage. This marriage of Oedipus to Jocasta fulfilled the rest of the prophecy. Oedipus and Jocasta had four children: sons Eteocles and Polynices (see "Seven Against Thebes") and daughters Antigone and Ismene.
