Eris

Ancient Greek personification of strife. Her Roman counterpart was Discordia. The daughter of Nyx and the sister of Ares, she was best known for her role in starting the Trojan War. When she alone was not invited to the wedding of Peleus and Thetis, she threw down among the guests a golden apple inscribed “for the most beautiful.” Hera, Athena, and Aphrodite each claimed it, and Zeus assigned the task of judging to the Trojan Paris. He awarded the apple to Aphrodite, who in turn helped him carry off the beautiful Helen, an act that triggered war.
