ANTAEUS, in Greek mythology, a giant of Libya, the son of Poseidon and Ge. He compelled all strangers who were passing through the country to wrestle with him, and as, if thrown, he derived fresh strength whenever he touched his mother earth, he proved invincible. Heracles, in combat with him, discovered the source of his strength, and lifting him up from the earth, crushed him to death. His tomb was shown at Tingis (Tangier).
