The story of Prince Ganymede is well known. His beauty was so great that Zeus himself was seized by an overmastering passion for him. Taking the form of an eagle, the god swooped down and bore the boy up to Olympus, where he served as Zeus’s beloved minion, companion, and cupbearer. To compensate Tros for the loss of his son, Zeus sent HERMES to him, bearing the gift of two divine horses, so swift and light they could gallop over water. Tros was consoled by these magical animals and by Hermes’s assurance that Ganymede was now and—by definition always would be—immortal.
