Antaeus was the son of Gaia and Poseidon. Challenging all who passed his way to a wrestling match to the death, Antaeus was invincible as long as he kept contact with the earth, which supplied him with all of his strength. During their match, Hercules was able to defeat the giant by lifting him from the ground. For a bronze with a similar pose, in the Walters Art Gallery, see no. 77a in Olmos and Balmaseda, "Antaios" in LIMC.
