In
Greek mythology,
Euryganeia (,
Eurygáneia) is occasionally named as
Oedipus' second wife and the mother of his children,
Polynices,
Eteocles,
Ismene and
Antigone. She was either a daughter of
Hyperphas or
Jocasta's sister. According to
Pausanias, the statement at
Odyssey 11.274—that that the gods
soon made the incestuous marriage between Oedipus and his mother Jocasta known—is incompatible with her bearing four children to him. The geographer cites the
Oedipodeia as evidence for the fact that Euryganeia was actually the mother of Oedipus' brood.
Pherecydes, on the other hand, attributed two sons (named
Phrastor and Laonytus) to the marriage of Jocasta and Oedipus, but agreed that the more famous foursome were the children of Euryganeia. There was a painting of her at
Plataea in which she was depicted as mournful because of the strife between her children. Following Euryganeia's death, Oedipus married
Astymedusa, who plotted against her stepsons.
