Antigone is a hero because she remains true both to the Gods and her brother. Even when faced with death, she refuses to go against either one, choosing to end her own life. Antigone does, in fact, have all three of these qualities, and thus is one of very few tragic heroines.The first quality of a tragic hero, the noble birth, is satisfied by the fact that Antigone is one of the four children of Oedipus: Polyneices, Eteocles, Ismene, and Antigone.
