Achilles Heel

💭 conceptἈχίλλειος Πτέρνα
Vulnerability, fatal weakness

A critical weakness that can lead to downfall despite overall strength, from the one spot where Achi‌​‌​‍​‌​‌​‍​‌​‌​‌​‍​‌​‍​‍​‍​‍​‌​‌​‍​‍​‌​‍​‍​‍​‌​‌​‍​‍​‍​‍​‍​‌​‌lles could be harmed.

The Meaning of Achilles Heel

When Achilles was born, his mother Thetis sought to make him immortal by dipping him in the river Styx.‌​‌​‍​‌​‌​‍​‌​‌​‌​‍​‌​‍​‍​‍​‍​‌​‌​‍​‍​‌​‍​‍​‍​‌​‌​‍​‍​‍​‍​‍​‌​‌ She held him by his heel, and that one small patch of skin never touched the magical water. Achilles grew into the greatest warrior of his generation, virtually invulnerable in battle. He slew Hector, the champion of Troy, and seemed unstoppable — until Paris, guided by Apollo, shot an arrow that struck the one vulnerable spot on his body: his heel. The mighty Achilles fell, brought down not by a great warrior but by a single well-aimed shaft to his only weakness. The English phrase "Achilles heel" entered common use to describe any fatal vulnerability in an otherwise strong position — a corporation's regulatory exposure, a boxer's glass jaw, or a nation's dependence on a single resource.
