When Heracles conveyed the golden apples to Eurystheus the latter presented them to the hero, whereupon Heracles placed the sacred fruit on the altar of Pallas-Athene, who restored them to the garden of the Hesperides.
12. Cerberus.—The twelfth and last labour which Eurystheus imposed on Heracles was to bring up Cerberus from the lower world, believing that all his heroic powers would be unavailing in the Realm of Shades, and that in this, his last and most perilous undertaking, the hero must at length succumb and perish.
Cerberus was a monster dog with three heads, out of whose awful jaws dripped poison; the hair of his head and back was formed of venomous snakes, and his body terminated in the tail of a dragon.
After being initiated into the Eleusinian Mysteries, and
obtaining from the priests certain information necessary for the accomplishment of his task, Heracles set out for Tænarum in Lacolia, where there was an opening which led to the under-world. Conducted by Hermes, he commenced his descent into the awful gulf, where myriads of shades soon began to appear, all of whom fled in terror at his approach, Meleager and Medusa alone excepted. About to strike the latter with his sword, Hermes interfered and stayed his hand, reminding him that she was but a shadow, and that consequently no weapon could avail against her.
Arrived before the gates of Hades he found Theseus and Pirithöus, who had been fixed to an enchanted rock by Aïdes for their presumption in endeavouring to carry off Persephone. When they saw Heracles they implored him to set them free. The hero succeeded in delivering Theseus, but when he endeavoured to liberate Pirithöus, the earth shook so violently beneath him that he was compelled to relinquish his task.
Proceeding further Heracles recognized Ascalaphus, who, as we have seen in the history of Demeter, had revealed the fact that Persephone had swallowed the seeds of a pomegranate offered to her by her husband, which bound her to Aïdes for ever. Ascalaphus was groaning beneath a huge rock which Demeter in her anger had hurled upon him, and which Heracles now removed, releasing the sufferer.
Before the gates of his palace stood Aïdes the mighty ruler of the lower world, and barred his entrance; but Heracles, aiming at him with one of his unerring darts, shot him in the shoulder, so that for the first time the god experienced the agony of mortal suffering. Heracles then demanded of him permission to take Cerberus to the upper-world, and to this Aïdes consented on condition that he should secure him unarmed. Protected by his breastplate and lion's skin Heracles went in search of the monster, whom he found at the mouth of the river Acheron. Undismayed by the hideous barking which proceeded from his three heads, he seized the
throat with one hand and the legs with the other, and although the dragon which served him as a tail bit him severely, he did not relinquish his grasp. In this manner he conducted him to the upper-world, through an opening near Troezen in Argolia.
