The Myth
The Nemean Lion was a monstrous lion that terrorized the hills around Nemea in Greece. Its golden fur was impervious to weapons, making it impossible to kill with ordinary arrows or blades, while its claws were sharper than mortal swords and could pierce even the strongest armour. Its origins vary between traditions: some accounts describe it as the offspring of Orthus and a monstrous female, while others name Typhon as its father. Another tradition claims that the lion was born from the Moon, when the goddess Selene cast it down at Hera’s request. Hera allowed the beast to roam her lands, knowing that it would become a formidable challenge for Heracles.
The Nemean Lion became the target of the first of Heracles’ twelve labours, imposed upon him by King Eurystheus. When Heracles first attacked the creature with his bow, his arrows bounced harmlessly off its golden hide. Realizing that ordinary weapons could not harm the beast, the hero drove it into its cave and blocked one of its two entrances. He then entered through the other opening and stunned the lion with his club. Finally, Heracles strangled the monster with his bare hands.
After killing the lion, Heracles discovered that he could not cut through its hide with his knife. According to tradition, the goddess Athena advised him to use one of the lion’s own claws to remove its skin. Heracles thereafter wore the impenetrable pelt as armour and its head as a helmet, making the lion’s hide a lasting symbol of his extraordinary strength. When he returned with the carcass, Eurystheus was so terrified that he ordered Heracles to present the results of his future labours outside the city gates. The king even had a large bronze jar made in which he could hide whenever the hero returned.
