Apple of discord

All the gods and goddesses were invited to the wedding of Peleus and Thetis, save one, Eris or "Strife." To avenge this slight, this goddess of discord tossed into the wedding hall a golden apple with the inscription "For The Fairest." It was immediately claimed by three rival goddesses: Hera, Athena, and Aphrodite. Zeus refused to decide the issue, but instead gave it to Paris, the son of Priam, king of Troy, to settle. The Judgment of Paris, as it has come to be known, bestowed the apple on Aphrodite, who had promised to Paris, the most beautiful woman in the world, namely Helen, wife of Menelaus, king of Sparta. The abduction of Helen by Paris was the cause of the ten-year siege and destruction of Troy under the onslaught of the Greek forces, pledged to wreak vengeance on the seducer. The apple of discord describes any action or situation that causes dissension and turmoil and is more trouble than it is worth.
