Achilles Cultural  
  1. In classical mythology, the greatest warrior on the Greek side in the Trojan War (see also Trojan War). When he was an infant, his mother tried to make him immortal by bathing him in a magical river, but the heel by which she held him remained vulnerable. During the Trojan War, he quarreled with the commander, Agamemnon, and in anger sulked in his tent. Eventually Achilles emerged to fight and killed the Trojan hero Hector, but he was wounded in the heel by an arrow and died shortly thereafter.

Achilles is the hero of Homer's Iliad.

People speak of an “Achilles' heel” as the one weak or sore point in a person's character.

The phrase “wrath of Achilles” refers to the hero's anger, which caused so much destruction that Homer refers to it as his main theme in the first line of the Iliad.

The Achilles tendon runs from the heel to the calf.
