In Greek mythology the Judgment of Paris was a beauty contest between three of the most beautiful goddesses on Mount Olympus: Aphrodite, the goddess of love; Hera, wife of mighty Zeus and Queen of the Gods; and Athena, goddess of wisdom and war. The winner of the contest will receive the prize of a golden apple.
It all started at the wedding of Thetis, the sea-goddess, and Peleus, the mortal. Angry at not being invited to the wedding, the goddess of discord, Eris, throws a golden apple among the assembled guests. The apple is inscribed with the words "To the fairest" and Aphrodite, Hera, and Athena all think that means them. Zeus intervenes in the dispute and decides that the only way to settle the issue is to get Paris, prince of Troy, to judge which goddess is the most beautiful. All three goddesses offer Paris gifts to make him choose them. But it's the wily Aphrodite who wins the contest. She offers Paris the prize of Helen, the beautiful wife of Menelaus, king of Sparta. Paris's subsequent abduction of Helen is the catalyst for the Trojan War.
