Antigone and Ismene heard with horror what Creon had decided. To Ismene, shocking as it was, overwhelming her with anguish for the pitiful dead body and the lonely, homeless soul, it seemed, nevertheless, that nothing could be done except to acquiesce [to accept without protest]. She and Antigone were utterly alone. All Thebes was exulting that the man who had brought war upon them should be thus terribly punished. "We are women," she told her sister. "We must obey. We have no strength to defy the State." "Choose your own part," Antigone said. "I go to bury the brother I love." –"The Royal House of Thebes"

"Is it not better to be poor and free than to have great wealth and be slaves?" she [Boadicea] asked. "And the Romans take not only our freedom but our wealth. They want to make us both slaves and beggars. Let us rise. O brothers and sisters, let us rise, and drive these robbers out of our land! Let us kill them every one! Let us teach them that they are no better than hares and foxes, and no match for greyhounds! We will fight, and if we cannot conquer, then let us die—yes, every one of us—die rather than submit."

–"The Story of a Warrior Queen"
