All gods and goddesses, as well as several mortals were invited to the wedding of Peleus and Tethys (the parents of Achilles). Only Éris, goddess of discord, was not invited. She was irritated by this, so she arrived at the wedding banquet with a golden apple, which had the inscription καλλίστῃ (kallistēi, "for the most beautiful"), and threw the apple between the goddesses. Aphrodite, Hera and Athena all claimed to be the most beautiful, and thus, the owner of the apple. The goddesses chose to let the matter be resolved by Zeus, who, not wanting to favor one of the goddesses, placed the choice in the hands of Paris, a prince of Troia.
The goddesses undressed for Paris on Mount Ida, yet, Paris could not decide, as all three were ideally beautiful, so the goddesses resorted to bribes. Hera offered control over all of Asia and Europe, while Athena offered wisdom, fame and glory in battle, and Aphrodite offered the love of the most beautiful mortal woman in the world, this woman was Helena, who was married to the king of Sparta, Menelaus .
Paris chose Aphrodite, and the other two goddesses were furious that they lost and favored the Greeks in the ensuing war, caused by the abduction of Helena by Paris. . In the war, Hera even wounded Artemis who protected the Trojans, and took Aphrodite's magic belt to favor the Greeks.
