Achille is a character from ancient Greek mythology, known for his role in the Trojan War. He is often depicted as a great warrior with unmatched strength and bravery. His mother, Thetis, dipped him in the River Styx to make him invulnerable, except for his heel, which became his only weakness. Achille's story is famously told in Homer's Iliad, where he is portrayed as a hero who struggles with pride and anger. His conflict with Agamemnon, the leader of the Greek forces, leads to significant events in the war, ultimately highlighting themes of honor and mortality.
