Ganymede was the son of Tros, founder of Troy. A youth of great beauty, he was abducted by Zeus while the young man was tending his flocks on Mt. Ida. Carried to Olympus either by an eagle, or Zeus himself in aquiline form, Ganymede served as the god’s cupbearer in place of Hebe, as well as his eromenos. This arrangement angered Hera to such a degree that she would abandon the Trojans in their war against the Greeks. To recompense Tros for the loss of his son, Zeus provided him with a pair of horses so swift, they could cross over water, and which were the ancestors of the horses for which the Trojans were renowned.
