Amphitryon, obliged to retire to Thebes, was there absolved by Creon; but when, as he thought, he was about to receive the hand of Alcmena, who accompanied him to the court of that prince, she declared that, not being satisfied with the revenge which her father had taken on the Teleboans, she would consent to be the prize of him who would undertake to declare war against them. Amphitryon accepted these conditions, and, forming an alliance with Creon, Cephalus, and some other princes, made a descent upon the islands which the enemy possessed, and, making himself master of them, bestowed one of them on his ally, Cephalus.
It was during this war that Hercules came into the world; and whether Amphitryon had secretly consummated his marriage before his departure, or whether he had returned privately to Thebes, or to Tirynthus, where Hercules was said to have been born, it was published, that Jupiter, to deceive Alcmena, had taken the form of her husband, and was the father of the infant Hercules. If this is not the true explanation of the story, it may have been invented to conceal some intrigue in which Alcmena was detected; or, in process of time, to account for the extraordinary strength and valour of Hercules, it may have been said that Jupiter, and not Amphitryon, was the father of Hercules. Indeed, we find Seneca, in one of his Tragedies, putting these words into the mouth of Hercules:— ‘Whether all that has been said upon this subject be held as undoubted truth, or whether it proves to be but a fable, and that my father was, after all, in reality, but a mortal; my mother’s fault is sufficiently effaced by my valour, and I have merit sufficient to have had Jupiter for my father.’ The more readily, perhaps, to account for the transcendent strength and prowess of Hercules, the story was invented, that Jupiter made the night on which he was received by Alcmena under the form of Amphitryon, as long as three, or, according to Plautus, Hyginus, and Seneca, nine nights. Some writers say that Alcmena brought forth twins, one of which, Iphiclus, was the son of Amphitryon, while Hercules had Jupiter for his father.
With respect to the metamorphosis of Galanthis, it is but a little episode here introduced by Ovid, to give greater plausibility to the other part of the story. It most probably originated in the resemblance of the names of that slave to that of the weazel, which the Greeks called γαλῆ. Ælian, indeed, tells us that the Thebans paid honour to that animal, because it had helped Alcmena in her labour. The more ancient poets also added, that Juno retarded the birth of Hercules till the mother of Eurystheus was delivered, which was the cause of his being the subject of that king; though others state that this came to pass by the command of the oracle of Delphi. This king of Mycenæ having ordered him to rid Greece of the numerous robbers and wild beasts that infested it, it is most probable that, as we learn from Dionysius of Halicarnassus, he performed this service at the head of the troops of Eurystheus. If this is the case, the persecutions which the poets have ascribed to the jealousy of Juno, really originated either in the policy or the jealousy of the court of Mycenæ.
As Ovid has here cursorily taken notice of the labours of Hercules, we may observe, that it is very probable that his history is embellished with the pretended adventures of many persons who bore his name, and, perhaps, with those of others besides. Cicero, in his ‘Treatise on the Nature of the Gods,’ mentions six persons who bore the name of Hercules; and possibly, after a minute examination, a much greater number might be reckoned, many nations of antiquity having given the name to such great men of their own as had rendered themselves famous by their actions. Thus, we find one in Egypt in the time of Osiris, in Phœnicia, among the Gauls, in Spain, and in other countries. Confining ourselves to the Grecian Hercules, surnamed Alcides, we find that his exploits have generally been sung of by the poets, under the name of the Twelve Labours; but, on entering into the detail of them, we find them much more numerous. Killing some serpents in his youth, it was published, not only that he had done so, but that they had been sent by Juno for the purpose of destroying him. The forest of Nemea serving as a retreat for a great number of lions that ravaged the country, Hercules hunted them, and, killing the most furious of them, always wore his skin.
Several thieves, having made the neighbourhood of Lake Stymphalus, in Arcadia, their resort, he freed the country of them; the nails and wings which the poets gave them, in representing them as birds, being typical of their voracity and activity. The marshes of Lerna, near Argos, were infested by great numbers of serpents, which, as fast as they were destroyed, were replaced by new swarms; draining the marshes, and, probably, setting fire to the adjacent thickets or jungles, he destroyed these pestilent reptiles, on which it was fabled that he had destroyed the Hydra of Lerna, with its heads, which grew as fast as they were cut off. The forest of Erymanthus was full of wild boars, which laid waste all the neighbouring country: he destroyed them all, and brought one with him to the court of Eurystheus, of a size so monstrous, that the king was alarmed on seeing it, and was obliged to run and hide himself.
The stables of Augeas, king of Elis, were so filled with manure, by reason of the great quantity of oxen that he kept, that Hercules being called upon to cleanse them, employed his engineering skill in bringing the river Alpheus through them. Having pursued a hind for a whole year, which Eurystheus had commanded him to take, it was circulated, probably on account of her untiring swiftness, that she had feet of brass. The river Acheloüs having overflowed the adjacent country, he raised banks to it, as already mentioned. Theseus was a prisoner in Epirus, where he had been with Pirithous, to bring away the daughter of Aidoneus. Hercules delivered him; and that was the foundation of the Fable which said that he had gone down to Hades, or Hell. In the cavern of Tænarus there was a monstrous serpent; this he was ordered to kill, and, probably, this gave rise to the story of Cerberus being chained by him. Pelias having been killed by his daughters, his son Acastus pursued them to the court of Admetus, who, refusing to deliver up Alcestis, of whom he was enamoured, was taken prisoner in an engagement, and was delivered by that princess, who herself offered to be his ransom. Hercules being then in Thessaly, he took her away from Acastus, who was about to put her to death, and returned her to Admetus. This, probably, was the foundation of the fable which stated, that he had recovered her from the Infernal Regions, after having vanquished death, and bound him in chains.
The Amazons were a nation of great celebrity in the time of Hercules, and their frequent victories had rendered them very formidable to their neighbours. Eurystheus ordered him to go and bring away the girdle of Hippolyta, or, in other words, to make war upon them, and to pillage their treasures. Embarking on the Euxine Sea, Hercules arrived on the banks of the Thermodon, and, giving battle to the female warriors, defeated them; killing some, and putting the rest to flight. He took Antiope, or Hippolyta, prisoner, whom he gave to Theseus; but her sister, Menalippa, redeemed herself by giving up the famous girdle, or, in other words, by paying a large ransom. It is very probable, that in that expedition, he slew Diomedes, the barbarous king of Thrace, and brought away his mares, which were said to have been fed by him on human flesh. In returning by way of Thessaly, he embarked in the expedition of the Argonauts; but, leaving them soon afterwards, he went to Troy, and delivered Hesione from the monster which was to have devoured her; but not receiving from Laomedon, the king, the recompense which had been promised him, he killed that prince, sacked the city, and brought away Hesione, whom he gave to Telamon, who had accompanied him on the expedition.
This is probably the extent of the labours of Hercules in Greece, Thrace, and Phrygia. The poets have made him engage in many other laborious undertakings in distant countries, which most probably ought not to be attributed to the Grecian Hercules. Among other stories told of him, it is said, that having set out to fight with Geryon, the king of Spain, he was so much incommoded by the heat of the sun, that his wrath was excited against the luminary, and he fired his arrows at it, on which, the Sun, struck with admiration at his spirited conduct, made him a present of a golden goblet. After this, embarking and arriving in Spain, he defeated Geryon, a prince who was famed for having three heads, which probably either meant that he reigned over the three Balearic islands of Maiorca, Minorca, and Iviza, or else that Hercules defeated three princes who were strictly allied. Having thence passed the straits of Gibraltar to go over to Africa, he fought with the Giant Antæus, who sought to oppose his landing. That prince was said to be a son of the Earth, and was reported to recover fresh strength every time he was thrown on the ground; consequently, Hercules was obliged to hold him in his arms, till he had squeezed him to death. The solution of this fable is most probably that Antæus, always finding succour in a country where he was known as a powerful monarch, Hercules took measures to deprive him of aid, by engaging him in a sea fight, and thereby defeated him, without much trouble, as well as the Pygmies, who were probably some African tribes of stunted stature, who came to his assistance.
Hercules, returning from these two expeditions, passed through Gaul with the herds of Geryon, and went into Italy, where Cacus, a celebrated robber, who had made the caverns of Mount Aventine his haunts, having stolen some of his oxen, he, with the assistance, according to Dionysius of Halicarnassus, of Evander and Faunus, destroyed him, and shared his spoils with his allies. In his journey from Africa, Hercules delivered Atlas from the enmity of Busiris, the tyrant of Egypt, whom he killed; and gave such good advice to the Mauritanian king, that it was said that he supported the heavens for some time on his own shoulders, to relieve those of Atlas. The latter, by way of acknowledgment of his services, made him a present of several fine sheep, or rather, according to Diodorus Siculus, of some orange and lemon trees, which he carried with him into Greece. These were represented as the golden apples watched by a dragon in the garden of the Hesperides. As the ocean there terminated the scene of his conquests, he was said to have raised two pillars on those shores, to signify the fact of his having been there, and the impossibility of proceeding any further.
The deliverance of Prometheus, as already mentioned; the death of the two brothers, the Cercopes, famous robbers; the defeat of the Bull of Marathon; the death of Lygis, who disputed the passage of the Alps with him; that of the giant Alcyaneus, who hurled at him a stone so vast that it crushed twenty-four men to death; that of Eryx, king of Sicily, whom he killed with a blow of the cestus, for refusing to deliver to him the oxen which he had stolen; the combat with Cycnus, which was terminated by a peal of thunder, which separated the combatants; another combat against the Giants in Gaul, during which, as it was said, Jupiter rained down vast quantities of stones; all these are also attributed to Hercules, besides many more stories, which, if diligently collected, would swell to a large volume.
