I. Who Was Achilles?

Achilles was the greatest warrior of the Greek heroic age and the central figure of Homer's Iliad, the foundational text of Western literature. Son of the mortal king Peleus and the sea nymph Thetis, he was a demigod of unmatched speed, strength, and martial skill. He was said to be nearly invulnerable — his mother had dipped him in the River Styx as an infant, rendering his body impervious to all weapons. All except his heel, where she had held him, which remained his one fatal weakness.

Achilles' story is one of rage, glory, and tragedy. He sailed to Troy with the Greek army and quickly established himself as the most feared fighter on either side. But when Agamemnon, commander of the Greeks, dishonored him by seizing his war-prize Briseis, Achilles withdrew from battle in furious pride. Without their champion, the Greeks suffered catastrophic losses — a spiral of destruction that forms the core narrative of the Iliad.

II. The Wrath of Achilles

Achilles's withdrawal from battle had devastating consequences. The Trojans, led by Hector, pushed the Greeks back to their ships and nearly destroyed the entire army. Achilles's beloved companion Patroclus, unable to watch the slaughter, donned Achilles's own armor and led the Myrmidons back into battle. He fought valiantly but was slain by Hector, who stripped the armor from his body.

The death of Patroclus transformed Achilles's cold rage into volcanic grief. He reconciled with Agamemnon, received magnificent new armor forged by Hephaestus, and returned to the battlefield in a frenzy of killing that turned the Scamander River red with blood. He hunted Hector around the walls of Troy three times before finally killing him in single combat, then dragged his body behind his chariot for twelve days — an act of desecration that horrified even the gods.

III. Death & Legacy

Achilles knew from prophecy that he was fated to die at Troy. He could have chosen a long, peaceful life at home in Phthia, but instead chose a short life of immortal glory — a choice that defined the Greek heroic ideal. He was eventually killed by an arrow to his vulnerable heel, guided by Apollo and shot by the Trojan prince Paris. The phrase "Achilles' heel" has entered virtually every language as a metaphor for a fatal weakness in an otherwise invincible being.
