The first of Hercules' twelve labours, set by his cousin King Eurystheus, was to slay the Nemean lion. While searching for the lion, Hercules fletched some arrows to use against it, not knowing that its golden fur was impenetrable. He discovered the fur's protective property when his arrow bounced harmlessly off the creature's thigh. Hercules then stunned the beast with his club and, using his immense strength, strangled it to death. After slaying the lion, he tried to skin it with a knife from his belt, but failed. He then tried sharpening the knife with a stone and even tried with the stone itself. Finally, Athena, noticing the hero's plight, told Hercules to use one of the lion's own claws to skin the pelt. Hercules used the pelt as his armour.
