157. His Labors. Eurystheus enjoined upon the hero a succession of desperate undertakings, which are called the twelve "Labors of Hercules." The first was the combat with the lion that infested the valley of Nemea, the skin of which Hercules was ordered to bring to Mycenæ. After using in vain his club and arrows against the lion, Hercules strangled the animal with his hands and returned, carrying its carcass on his shoulders; but Eurystheus, frightened at the sight and at this proof of the prodigious strength of the hero, ordered him to deliver the account of his exploits, in future, outside the town.

His second labor was the slaughter of the Hydra, a water serpent that ravaged the country of Argos and dwelt in a swamp near the well of Amymone. It had nine heads, of which the middle one was immortal. Hercules struck off the heads with his club; but in the place of each dispatched, two new ones appeared. At last, with the assistance of his faithful nephew Iolaüs, he burned away the other heads of the Hydra and buried the ninth, which was immortal, under a rock.

His third labor was the capture of a boar that haunted Mount Erymanthus in Arcadia. The adventure was, in itself, successful. But on the same journey Hercules made the friendship of the centaur Pholus, who, receiving him hospitably, poured out for him without stint the choicest wine that the centaurs possessed. As a consequence, Hercules became involved in a broil with the other centaurs of the mountain. Unfortunately his friend Pholus, drawing one of the arrows of Hercules from a brother centaur, wounded himself therewith and died of the poison.
The fourth labor of Hercules was the capture of a wonderful stag of golden antlers and brazen hoofs, that ranged the hills of Cerynea, between Arcadia and Achaia.
His fifth labor was the destruction of the Stymphalian birds, which with cruel beaks and sharp talons harassed the inhabitants of the valley of Stymphalus, devouring many of them.
