4. The Hind of Cerynea.—This animal, which was sacred to the Arcadian Artemis, had golden horns and brazen hoofs, the latter being a symbol of its untiring fleetness. Heracles was commanded to bring it alive to Mycenæ, and for a whole year he continued to pursue it over hill and dale with untiring energy. At length it returned to Arcadia, where he succeeded in capturing it on the banks of the Ladon, and bore it in triumph to Mycenæ.
5. The Stymphalian Birds.—These voracious birds, which fed on human flesh, had brazen claws, wings, and beaks, and were able to shoot out their feathers like arrows. They inhabited the district round Lake Stymphalis in Arcadia. Heracles slew some, and so terrified the rest by means of his brazen rattle that they never returned. This latter circumstance is apparently an addition of later times, to explain their reappearance in the history of the Argonauts.
6. Cleansing of the Stables of Augeas.—The sixth task of Heracles was to cleanse in one day the stables of Augeas, king of Elis, whose wealth in cattle had become proverbial. Heracles repaired to Elis, where he offered to cleanse the stables, in which were three thousand oxen, if the king would consent to give him a tenth part of the cattle. Augeas agreed to do so; Heracles then turned the course of the Peneus or the Alpheus, or, according to some, of both rivers, through the stalls, and thus carried off the filth. Augeas, however, on learning that Heracles had undertaken the labour at the command of Eurystheus, refused to give him the stipulated reward, a breach of faith for which Heracles, later, took terrible vengeance on the king.
7. The Cretan Bull.—In the history of Minos, king of Crete, we find that Poseidon once sent up a bull out of the sea for Minos to sacrifice, but that Minos was induced by the beauty of the animal to place it among his own herds, and sacrificed another in its stead; whereupon Poseidon drove the bull mad. The seventh labour of Heracles consisted in capturing this bull and bringing it to Mycenæ. It was afterwards set free by Eurystheus, and appears later, in the story of Theseus, as the bull of Marathon.
8. The Mares of Diomedes.—Diomedes was king of the Bistones, a warlike tribe of Thrace. He inhumanly caused all strangers cast upon his coasts to be given to his wild mares, who fed on human flesh. To bind these horses and bring them alive to Mycenæ was the next task of Heracles. This, too, he successfully accomplished, after inflicting on Diomedes the same fate to which he had condemned so many others.
9. The Girdle of Hippolyte.—Admete, the daughter of Eurystheus, was anxious to obtain the girdle which the queen of the Amazons had received from Ares; and Heracles was accordingly despatched to fetch it. After various adventures he landed in Themiscyra, and was at first kindly received by Hippolyte, who was willing to give him the girdle. But Hera, in the guise of an Amazon, spread a report that Heracles was about to carry off the queen, upon which the Amazons attacked Heracles and his followers. In the battle which ensued Hippolyte was killed, and the hero, after securing the girdle, departed. On his journey homewards occurred his celebrated adventure with Hesione, the daughter of Laomedon, king of Troy. This king had refused Poseidon and Apollo the rewards he had promised them for their assistance in building the walls of Troy. In consequence of his perfidy, Apollo visited the country with a pestilence, and Poseidon sent a sea-monster, which devastated the land far and wide. By the advice of the oracle, Hesione, the king’s daughter, was exposed to be devoured by the animal. Heracles offered to destroy the monster, if Laomedon would give him the horses which his father Tros had received as a compensation for the loss of Ganymedes. Laomedon agreed, and Heracles then slew the monster. Laomedon, however, again proved false to his word, and Heracles, with a threat of future vengeance, departed.
10. The Oxen of Geryones.—The next task of Heracles was to fetch the cattle of the three-headed winged giant Geryones, or Geryoneus (Geryon). This monster was the offspring of Chrysaor (red slayer) and Callirrhoë (fair-flowing), an Oceanid, and inhabited the island of Erythia, in the far West, in the region of the setting sun, where he had a herd of the finest and fattest cattle. It was only natural that Heracles, in the course of his long journey to Erythia and back, should meet with numerous adventures; and this expedition has, accordingly, been more richly embellished than any other by the imagination of the poets. He is generally supposed to have passed through Libya, and to have sailed thence to Erythia in a golden boat, which he forced Helios (the sun) to lend him by shooting at him with his arrows. Having arrived in Erythia, he first slew the herdsman who was minding the oxen, together with his dog. He was then proceeding to drive off the cattle, when he was overtaken by Geryon. A violent contest ensued, in which the three-headed monster was at length vanquished by the arrows of the mighty hero. Heracles is then supposed to have recrossed the ocean in the boat of the sun, and, starting from Tartessus, to have journeyed on foot through Iberia, Gaul, and Italy. We pass over his contests with the Celts and Ligurians, and only notice briefly his victory over the giant Cacus, mentioned by Livy, which took place in the district where Rome was afterwards built, because Roman legend connected with this the introduction of the worship of Hercules into Italy. At length, after many adventures, he arrived at Mycenæ, where Eurystheus sacrificed the oxen to the Argive goddess Hera.
Heracles has now completed ten of his labours, but Eurystheus, as Apollodorus relates, refused to admit the destruction of the Lernæan Hydra, because on that occasion Heracles had availed himself of the help of Iolaüs, or the cleansing of the stables of Augeas, because of the reward for which he had stipulated; so that the hero was compelled to undertake two more. This account does not, however, harmonise with the tradition of the response of the oracle, in deference to which Heracles surrendered himself to servitude, and which offered the prospect of twelve labours from the first.
11. The Apples of the Hesperides.—This adventure has been even more embellished with later and foreign additions than the last. The golden apples, which were under the guardianship of the Hesperides, or nymphs of the west, constituted the marriage present which Hera had received from Gæa on the occasion of her marriage with Zeus. They were closely guarded by the terrible dragon Ladon, who, like all monsters, was the offspring of Typhon and Echidna. This, however, was far less embarrassing to the hero than his total ignorance of the site of the garden of the Hesperides, which led him to make several fruitless efforts before he succeeded in reaching the desired spot.
His first object was to gain information as to the situation of the garden, and for this purpose he journeyed through Illyria to the Eridanus (Po), in order to inquire the way of the nymphs who dwelt on this river. By them he was referred to the treacherous sage Nereus, whom he managed to seize whilst asleep, and refused to release until he had obtained the desired information. Heracles then proceeded by way of Tartessus to Libya, where he was challenged to a wrestling match by the giant Antæus, a powerful son of Earth, who was, according to Libyan tradition, of a monstrous height (some say sixty cubits). He was attacked by Heracles, but, as he received new strength from his mother Earth as often as he touched the ground, the hero lifted him up in the air and squeezed him to death in his arms.
