Then, with strength to meet the horrors of the underworld, Hercules traveled on to Peloponnesus, and to the Laconian city of Taenarus, which contained the opening to the lower world. Here, accompanied by Mercury, he descended through a cleft in the earth, and came to the entrance of the city of King Pluto. The shades which sadly wandered back and forth before the gates of the city took flight as soon as they caught sight of flesh and blood in the form of a living man. Only the Gorgon Medusa and the spirit of Meleager remained. The former Hercules wished to overthrow with his sword, but Mercury touched him on the arm and told him that the souls of the departed were only empty shadow pictures and could not be wounded by mortal weapons. With the soul of Meleager the hero chatted in friendly fashion, and received from him loving messages for the upper world. Still nearer to the gates of Hades Hercules caught sight of his friends Theseus and Pirithous. When both saw the friendly form of Hercules they stretched beseeching hands towards him, trembling with the hope that through his strength they might again reach the upper world. Hercules grasped Theseus by the hand, freed him from his chains and raised him from the ground. A second attempt to free Pirithous did not succeed, for the ground opened beneath his feet. At the gate of the City of the Dead stood King Pluto, and denied entrance to Hercules. But with an arrow the hero shot the god in the shoulder, so that he feared the mortal; and when Hercules then asked whether he might lead away the dog of Hades he did not longer oppose him. But he imposed the condition that Hercules should become master of Cerberus without using any weapons. So the hero set out, protected only with cuirass and the lion skin. He found the dog camping near the dwelling of Acheron, and without paying any attention to the bellowing of the three heads, which was like the echo of fearful resounding thunder, he seized the dog by the legs, put his arms around his neck, and would not let him go, although the dragon tail of the animal bit him in the cheek. He held the neck of Cerberus firm, and did not let go until he was really master of the monster. Then he raised it, and through another opening of Hades returned in happiness to his own country. When the dog of Hades saw the light of day he was afraid and began to spit poison, from which poisonous plants sprung up out of the earth. Hercules brought the monster in chains to Tirynth, and led it before the astonished Eurystheus, who could not believe his eyes. Now at last the king doubted whether he could ever rid himself of the hated son of Jupiter. He yielded to his fate and dismissed the hero, who led the dog of Hades back to his owner in the lower world. Thus Hercules after all his labors was at last set free from the service of Eurystheus, and returned to Thebes. DEUCALION AND PYRRHA
