where does the word achilles heel come from
Achilles' heel In Greek mythology, when Achilles was a baby, it was foretold that he would die young. To prevent his death, his mother Thetis took Achilles to the River Styx, which was supposed to offer powers of invulnerability, and dipped his body into the water; however, as Thetis held Achilles by the heel, his heel was not washed over by the water of the magical river. Achilles grew up to be a man of war who survived many great battles. One day, a poisonous arrow shot at him was lodged in his heel, killing him shortly afterwards.
Hector A 2004 film version of Troy has Achilles slaying Hector following a duel, whereas in the Iliad it is rather different. In the Iliad, Hector remains outside the walls, while his army flees into the city. As Achilles approaches, Hector stands his ground, fights and dies upon looking up at Troy. The film version of his death more resembles the single combat between the champions mentioned by Achilles in the Iliad, book 9.
