Ismene

In Greek mythology, Ismene is a Theban princess. She is the daughter and half-sister of Oedipus, king of Thebes, daughter and granddaughter of Jocasta, and sister of Antigone, Eteocles, and Polynices. She appears in several tragic plays of Sophocles: at the end of Oedipus Rex, in Oedipus at Colonus and in Antigone. She also appears at the end of Aeschylus' Seven Against Thebes. In Sophocles Oedipus Rex Ismene is not named, but is seen at the end of Oedipus Rex as her father/brother laments the "shame" and "sorrow" he is leaving her and her sister. Oedipus begs Creon to watch over them, but in his grief reaches to take them with him as he is led away. Creon prevents him from taking his daughters out of the city with him. Oedipus at Colonus Ismene appears in Oedipus at Colonus to tell her father of the situation in Thebes and the rivalry of his sons. She explains that Eteocles has taken the throne from Polynices and driven him out of the city. As a result of this, Polynices gathered his own army to either take back the city "or to die there with honor." According to the Oracle of Delphi, the location where Oedipus is buried will determine the result of the war between the brothers. Ismene tells her father that Creon plans to have him buried on the border of Thebes so that they will have the desirable outcome. Hearing this, Oedipus curses his sons and refuses to leave Colonus.
