The Oedipus Trilogy was my serious summer read, but I found myself quite alarmed when I reached the end of Antigone. My question is: What happens to Ismene, Antigone's sister?
At the end of Oedipus Rex, Antigone and Ismene are brought out to bid their father Oedipus fare well; in Oedipus at Colonnus, Ismene plays a rather important role in beseeching the gods to allow her father to live uncursed on holy ground; and of course in Antigone, Ismene acts as a foil to her noble and stubborn sister. But after she attempts to share responsibility with Antigone for burying her brother Polynices, she disappears. What happens to her? (Does she die?)
Sophocles seems to ignore her fate completely--and I find this unsettling. Can anyone help?
