In Greek mythology, Ismene was the youngest child of Oedipus and Jocasta, and the sister of Antigone, Eteocles and Polynices. When Antigone proposed to bury Polynices against King Creon of Thebes' orders, Ismene refused to help, but when Antigone was arrested and charged with the burial, she tried to share the blame, only to be rejected contemptuously by her sister.
