This 'swift-footed' warrior is the greatest on the Greek side. His father is Peleus, a great warrior in his own right, and his mother is Thetis, a sea nymph. The consequences of Achilles' rage at Agamemnon for confiscating his geras (prize of honor) are the subject of the Iliad. Achilles kills Hector, but is killed by a poisoned arrow in the heel, the only vulnerable place on his body.
