In Greek mythology, Achilles’ mother, Thetis, dipped the infant Achilles into the magical River Styx to make him immortal and invulnerable to wounds. However, she held him by his left heel, leaving that small spot untouched by the enchanted waters. This un-submerged area became his only weakness—the proverbial “Achilles’ heel”. 

Because the water could not touch the heel, this remained the only part of his body where he could be harmed. 

• The Prophecy: It was prophesied that Achilles would either live a long, obscure life or die a quick but glorious death in the Trojan War. Thetis tried to protect him by hiding him and dipping him in the river. 
• The Fatal Strike: During the Trojan War, Achilles was a fierce and undefeated warrior. Eventually, the Trojan prince Paris (guided by the god Apollo) shot a poisoned arrow into his vulnerable heel. The wound proved fatal, fulfilling the original prophecy. 
• The Legacy: This famous myth gives us both the metaphorical phrase “Achilles’ heel” (meaning someone’s point of weakness) and the anatomical term for the Achilles tendon in our legs.

Greek mythology, Achilles never officially married, but he had a recognized consort named Deidamia and a beloved captive known as Briseis. 

• Deidamia: She is considered his true wife in several ancient traditions. A princess of Skyros, she married Achilles while he was hidden on her island disguised as a girl to avoid the Trojan War. They had a son together named Neoptolemus. 
• Briseis: While she was originally a captive and war prize taken during the sack of Lyrnessos, Achilles was deeply devoted to her. In Homer’s Iliad, Achilles often refers to her as his wife or bride, and their forced separation is the main catalyst for his rage and withdrawal from the Trojan War.

Achilles was not a god, but rather a demigod—the mortal son of the sea nymph Thetis and the mortal King Peleus of Phthia. Despite being mortal, he is the greatest and most formidable warrior in Greek mythology, famous for his unparalleled strength, courage, and pride. 

Because he was born to a goddess, he possessed godlike battle prowess and was considered virtually invincible. A closer look at the defining aspects of his myth highlights why he is often mistakenly thought to be a god: 

• Invulnerability: According to legend (famously recorded by the Roman poet Statius), his mother Thetis dipped the infant Achilles into the magical River Styx, making his skin entirely invulnerable to weapons. However, she held him by his heel, leaving that spot wet-less and vulnerable—the origin of the idiom “Achilles’ heel”. 
• The Trojan War: He is the central hero of Homer’s Iliad, which chronicles his crucial role in the Greek army during the Trojan War. 
• His Choice of Fate: Before the war, Achilles learned from the gods that he had two possible destinies: he could live a long, quiet, and uneventful life, or die young in battle but achieve everlasting glory. He chose the path of glory.
