In
Greek mythology,
Astymedusa (,
Astymédousa) is occasionally named as a later wife of
Oedipus. After parting with
Jocasta or after the death of
Euryganeia, who was his second wife, Oedipus married Astymedousa. Astymedusa accused
Polynices and
Eteocles of attempting to rape her, thus driving Oedipus into a frenzy. This is held as an alternate cause for the curse which led to the fraternal discord at the heart of the myth of the wars at
Thebes.
