In Greek mythology, Achilles (Ancient Greek: , Achilleus) was a Greek hero of the Trojan War, the central character and the greatest warrior of Homer's Iliad.
Achilles also has the attributes of being the most handsome of the heroes assembled against Troy.
Later legends (beginning with a poem by Statius in the first century AD) state that Achilles was invulnerable in all of his body except for his heel. Since he died due to a poisonous arrow shot into his heel, the term "Achilles' heel" has come to mean a person's principal weakness.
Achilles was the son of the nymph Thetis and Peleus, the king of the Myrmidons. Zeus and Poseidon had been rivals for the hand of Thetis until Prometheus, the fire-bringer, warned Zeus of a prophecy that Thetis would bear a son greater than his father. For this reason, the two gods withdrew their pursuit, and had her wed Peleus.
