Then the animal raised his bloody head; looked around in every direction, and in fierce anger showed his ugly teeth. Raising his head, he exposed his heart, and immediately Hercules let fly another arrow, hoping to pierce him through the lungs. Again the arrow did not enter the flesh, but fell at the feet of the monster. Hercules took a third arrow, while the lion, casting his eyes to the side, watched him. His whole neck swelled with anger; he roared, and his back was bent like a bow. He sprang toward his enemy; but Hercules threw the arrow and cast off the lion skin in which he was clothed with the left hand, while with the right he swung his club over the head of the beast and gave him such a blow on the neck that, all ready to spring as the lion was, he fell back, and came to a stand on trembling legs, with shaking head. Before he could take another breath, Hercules was upon him. Throwing down his bow and quiver, that he might be entirely unencumbered, he approached the animal from behind, threw his arm around his neck and strangled him. Then for a long time he sought in vain to strip the fallen animal of his hide. It yielded to no weapon or no stone. At last the idea occurred to him of tearing it with the animal's own claws, and this method immediately succeeded. Later he prepared for himself a coat of mail out of the lion's skin, and from the neck, a new helmet; but for the present he was content to don his own costume and weapons, and with the lion's skin over his arm took his way back to Tirynth. THE SECOND LABOR The second labor consisted in destroying a hydra. This monster dwelt in the swamp of Lerna, but came occasionally over the country, destroying herds and laying waste the fields. The hydra was an enormous creature--a serpent with nine heads, of which eight were mortal and one immortal. Hercules set out with high courage for this fight. He mounted his chariot, and his beloved nephew Iolaus; the son of his stepbrother Iphicles, who for a long time had been his inseparable companion, sat by his side, guiding the horses; and so they sped toward Lerna. At last the hydra was visible on a hill by the springs of Amymone, where its lair was found. Here Iolaus left the horses stand. Hercules leaped from the chariot and sought with burning arrows to drive the many-headed serpent from its hiding place. It came forth hissing, its nine heads raised and swaying like the branches of a tree in a storm. Undismayed, Hercules approached it, seized it, and held it fast. But the snake wrapped itself around one of his feet. Then he began with his sword to cut off its heads. But this looked like an endless task, for no sooner had he cut off one head than two grew in its place. At the same time an enormous crab came to the help of the hydra and began biting the hero's foot. Killing this with his club, he called to Iolaus for help.
