In Greek mythology, Memnon was an Ethiopian king and son of Tithonus and Eos. As a warrior he was considered to be almost Achilles' equal in skill. During the Trojan War, he brought an army to Troy's defense. The death of Memnon echoes that of Hector, another defender of Troy whom Achilles also killed out of revenge for a fallen comrade, Patroclus. After Memnon's death, Zeus was moved by Eos' tears and granted him immortality.
