Jocasta

Jocasta (Iocasta in Latin) was a daughter of Menoeceus of Thebes, a descendant of the original Spartoi, and brother to Creon. She married King Laius, although an oracle warned them against having children because any child was destined to kill his father and marry his mother. Thus, when they conceived Oedipus accidentally, the baby was left to die on Mount Cithaeron (although he was rescued and brought up in Corinth). Oedipus later went to Thebes and solved the famous riddle of the sphinx, upon which he became king and married the widowed queen Jocasta, unaware that she was actually his own mother. Jocasta and Oedipus went on to have four children together, Antigone, Ismene, Eteocles and Polynices. When Oedipus eventually discovered the truth of his origin, he blinded and exiled himself, while Jocasta hanged herself.
