Birth and Achilles' HeelEdit
Achilles was the son of Peleus and Thetis. Thetis, his mother, attempted to make him immortal like the gods by dipping Achilles in the river Styx. However, there was one vital spot that was not covered: his heel, the area Thetis was holding. As a result, Achilles' heel was the only vulnerable spot that could kill him.
Achilles was the main character in the Iliad. Agamemnon had taken a woman named Chryseis as his slave. Her father Chryses, a priest of Apollo, begged Agamemnon to return her to him. Agamemnon refused and Apollo sent a plague amongst the Greeks. The prophet Calchas knew exactly the cause of the plague, but would only reveal it if Achilles would protect him. Achilles agreed, and Calchas declared Chryseis must be returned Chryses. Agamemnon reluctantly returned Chryseis, but he captured Achilles's daughter Briseis to replace her. Angry at this loss, Achilles decided to fight, but his mother urged him not to. Achilles prayed to Thetis to convince Zeus to help the Trojans fight against the Greeks in the Trojan War, and she agreed.
