On his voyage home the hero stopped at Troy, where a new adventure awaited him.
During the time that Apollo and Poseidon were condemned by Zeus to a temporary servitude on earth, they built for king Laomedon the famous walls of Troy, afterwards so renowned in history; but when their work was completed the king treacherously refused to give them the reward due to them. The incensed deities now combined to punish the offender. Apollo sent a pestilence which decimated the people, and Poseidon a flood, which bore with it a marine monster, who swallowed in his huge jaws all that came within his reach.
In his distress Laomedon consulted an oracle, and was informed that only by the sacrifice of his own daughter Hesione could the anger of the gods be appeased. Yielding at length to the urgent appeals of his people he consented to make the sacrifice, and on the arrival of Heracles the maiden was already chained to a rock in readiness to be devoured by the monster.
When Laomedon beheld the renowned hero, whose marvellous feats of strength and courage had become the wonder and admiration of all mankind, he earnestly implored him to save his daughter from her impending fate, and to rid the country of the monster, holding out to him as a reward the horses which Zeus had presented to
his grandfather Tros in compensation for robbing him of his son Ganymede.
Heracles unhesitatingly accepted the offer, and when the monster appeared, opening his terrible jaws to receive his prey, the hero, sword in hand, attacked and slew him. But the perfidious monarch once more broke faith, and Heracles, vowing future vengeance, departed for Mycenæ, where he presented the girdle to Eurystheus.
10. The Oxen of Geryones.—The tenth labour of Heracles was the capture of the magnificent oxen belonging to the giant Geryon or Geryones, who dwelt on the island of Erythia in the bay of Gadria (Cadiz). This giant, who was the son of Chrysaor, had three bodies with three heads, six hands, and six feet. He possessed a herd of splendid cattle, which were famous for their size, beauty, and rich red colour. They were guarded by another giant named Eurytion, and a two-headed dog called Orthrus, the offspring of Typhon and Echidna.
In choosing for him a task so replete with danger, Eurystheus was in hopes that he might rid himself for ever of his hated cousin. But the indomitable courage of the hero rose with the prospect of this difficult and dangerous undertaking.
After a long and wearisome journey he at last arrived at the western coast of Africa, where, as a monument of his perilous expedition, he erected the famous "Pillars of Hercules," one of which he placed on each side of the Straits of Gibraltar. Here he found the intense heat so insufferable that he angrily raised his bow towards heaven, and threatened to shoot the sun-god. But Helios, far from being incensed at his audacity, was so struck with admiration at his daring that he lent to him the golden boat with which he accomplished his nocturnal transit from West to East, and thus Heracles crossed over safely to the island of Erythia.
No sooner had he landed than Eurytion, accompanied by his savage dog Orthrus, fiercely attacked him; but Heracles, with a superhuman effort, slew the dog and
