Antigone's sister is named Ismene. At the beginning of the play, Antigone tries to persuade Ismene to help her bury their brother Polyneices, whose body was left to rot on the battlefield. However, their uncle Creon, who is now the king, and decreed that anyone who dares to give his nephew a proper burial will be stoned to death. So Ismene is too afraid to help Antigone and tries to talk her out of her plans. When Antigone gets caught, Creon blames Ismene too for not telling him what her sister was planning to do.
What a family!
Ismene is the sister of Antigone. Unlike Antigone, Ismene is afraid to take action against Creon's orders concerning her brother.
