Μemnon: An Ethiopian king, demigod, and Greek hero whose skill in battle was considered to be almost equal to Achilles. In ancient Greek mythology, Memnon was born of Tithonus, a mortal prince of Troy, and Eos, immortal goddess of the dawn. Known as the “son of Dawn,” Memnon was raised by Hesperides, nymphs associated with the evening and golden sunsets. According to the lost epic poem Aethiopis, Memnon returned from his kingdom in Ethiopia to defend Troy during the Trojan war, killing Antilochus, a favorite of Achilles. Hydrias like this one from approximately 500 B.C. depict the great battle between the two heroes, Memnon and Achilles, as their goddess mothers, Eos and Thetis, watched close by. Achilles ultimately killed Memnon, who falls into the devastated arms of Eos and is carrried back to Ethiopia. Moved by her tears, Zeus grants Memnon immortality.
