Mount Ida was the mountain associated with the golden apple judgment in Greek mythology.
The Judgment of Paris began when Eris, goddess of strife, threw a golden apple marked for the fairest at a divine gathering. Hera, Athena, and Aphrodite each claimed it. Zeus avoided choosing among them and appointed Paris, a Trojan prince, as judge.
Paris judged the goddesses on Mount Ida near Troy, traditionally identified with the Phrygian or Trojan Mount Ida rather than Crete’s Mount Ida. Each goddess offered him a reward: power from Hera, wisdom and victory in war from Athena, or the love of the most beautiful woman from Aphrodite. Paris chose Aphrodite, whose promise led to his taking Helen and helped cause the Trojan War.
The name Mount Ida can cause confusion because Crete also has a Mount Ida, linked with Zeus’s upbringing.
