The penalty of death was promulgated against any who should defy this order.
Antigone was distraught. Polynices had been left unburied, unwept, a feast of flesh for keen eyed carrion birds. Antigone asks her sister Ismene, for it was a challenge to her royal blood. “Now it is time to show whether or not you are worthy of your royal blood, is he not my brother and yours ? Whether you like it or not ? I shall never desert him- never I” But Ismene responds, “How could you dare,when Creon has expressly forbidden it? Antigone, we are women, it is not for us to fight against men.” With a touch of bitter ness, Antigone releases her sister from the obligation to help her, but argues she cannot shrug off the burden. “If  I die for it what happiness Live, if you will live, and defy the holiest of laws of heaven.”
