Overview
In Greek mythology, Jocasta, also rendered Iocaste and also known as Epicaste, was a daughter of Menoeceus, a descendant of the Spartoi Echion, and queen consort of Thebes. She was the wife of first Laius, then of their son Oedipus, and both mother and grandmother of Antigone, Eteocles, Polynices and Ismene. She was also sister of Creon and mother-in-law of Haimon.
Life
After Laius' abduction and rape of Chrysippus of Elis, Laius married Jocasta. Laius received an oracle from Delphi which told him that he must not have a child with his wife, or the child would kill him and marry her; in another version, recorded by Aeschylus, Laius is warned that he can only save the city if he dies childless. One night, Laius became drunk and fathered Oedipus with Jocasta.
Jocasta handed the newborn infant over to Laius. Jocasta or Laius pierced and pinned the infant's ankles together. Laius instructed his chief shepherd, Menoetes (not to be confused with Menoetes, the underworld spirit) a slave who had been born in the palace, to expose the infant on Cithaeron and leave it to die. Laius' shepherd took pity on the infant and gave him to another shepherd in the employ of King Polybus of Corinth. Childless, Polybus and his queen, Merope of Corinth (according to Sophocles, or Periboea according to Pseudo-Apollodorus), raised the infant to adulthood.
Oedipus grew up in Corinth under the assumption that he was the biological son of Polybus and his wife. Hearing rumors about his parentage, he consulted the Delphic Oracle. Oedipus was informed by the Oracle that he was fated to kill his father and to marry his mother. Fearing for the safety of the only parents known to him, Oedipus fled from Corinth before he could commit these sins. During his travels, Oedipus encountered Laius on a narrow pass at Phocis. After a heated argument regarding right-of-way, Oedipus killed Laius, unknowingly fulfilling the first half of the prophecy. Oedipus continued his journey to Thebes and discovered that the city was being terrorized by the sphinx. Oedipus solved the sphinx's riddle, and the grateful city, along with the acting regent Creon, elected Oedipus as its new king. Oedipus accepted the throne and married Laius' widowed queen Jocasta, Oedipus’ actual mother, thereby fulfilling the second half of the prophecy. Jocasta bore her son's four children: two girls, Antigone and Ismene, and two boys, Eteocles and Polynices.
