4. Perseus.—Acrisius, the brother of Prœtus, had a daughter called Danaë, whose fortune it was to gain the love of the great ruler of Olympus. Her father, Acrisius, was induced by an oracle, which foretold that he should be killed by his own grandson, to immure Danaë in a subterraneous chamber. Zeus, however, in his love for her, changed himself into a shower of golden rain, and thus introduced himself through the roof of her prison. Thus was the god-like hero Perseus born. There can be no doubt that this myth, too, is founded on the idea of the bridal union of heaven and earth; this is one of the pictures of nature which the mind most readily forms. Danaë represents the country of Argos; her prison is the heaven, enveloped, during the gloomy months of winter, with thick clouds. Her offspring by Zeus represents the light of the sun, which returns in the spring-time and begins, like a veritable hero, its contest with the powers of death and darkness. The Gorgon Medusa has the same significance in the history of Perseus that the hideous Python has in that of Apollo.

The legend then proceeds to relate that Acrisius, having heard of the birth of his grandson, to avert the fate threatened by the oracle, ordered mother and child to be confined in a chest and cast into the sea. But human wisdom avails nought against the inevitable decrees of heaven. The chest was cast by the waves on the rocky island of Seriphus, where it was found by the fisherman Dictys; and Danaë and her child were hospitably received and cared for by Dictys and his brother Polydectes, the ruler of the island. The latter, however, subsequently wished to marry Danaë, and on her rejecting his advances made her a slave. Fearing the vengeance of Perseus, he despatched him, as soon as he was grown up, on a most perilous adventure. This was no other than to bring him the head of the Gorgon Medusa—a terrible winged woman, who dwelt with her two sisters, the daughters of Phorcys and Ceto, on the farthest western shore of the earth, on the border of Oceanus. Perseus set out, though he was in the greatest perplexity how to accomplish so perilous a task. Hermes, however, at this juncture came to his aid; and Athene, the special patroness of heroes, inspired him with courage. These deities first showed him how to procure the necessary means for accomplishing his undertaking, which consisted of an invisible helmet, a magic wallet, and a pair of winged sandals. All these were in the hands of the Nymphs, by whom probably the water-nymphs are meant. The way to their abode he could only learn from the Grææ. These creatures, who were likewise the daughters of Phorcys and Ceto, were reported to have come into the world as old women; their very appearance was appalling, and they had but one eye and one tooth between them, of which they made use in turn. They, too, dwelt on the outskirts of the gloomy region inhabited by the Gorgons, whence they are called by Æschylus their sentinels. Under the guidance of Apollo and Athene, Perseus came to the Grææ. He then robbed them of their one eye and one tooth, and thus forced them to tell him the way to the habitations of the Nymphs. From the latter he at once obtained the objects he sought; and having donned his winged sandals, he hastened to the abode of the Gorgons, whom he fortunately discovered asleep. Athene then pointed out to him Medusa—the other two sisters, Stheno and Euryale, being immortal—and enjoined him to approach them carefully backwards, as the sight of their faces would infallibly turn any mortal into stone. With the help of her mirror-like shield and the sickle of Hermes, Perseus succeeded in cutting off the head of Medusa without looking round; and having placed the head in his wallet, he hastened away. His helmet, which rendered him invisible, enabled him to escape the pursuit of the other Gorgons, who had meanwhile awaked. From the trunk of Medusa sprang the winged horse Pegasus, and Chrysaor, the father of Geryones. On his return to Seriphus, Perseus turned the unrighteous Polydectes into stone by means of the Gorgon’s head, which he then presented to Athene; and after making his benefactor, Dictys, king of the island, he turned his steps towards his native place, Argos. Such are the essential features of the myth—concerning which, in spite of its antiquity, we have no earlier sources of information—such is the original framework on which was afterwards built up the history of the further adventures of the hero. The most celebrated of these was the rescue of Andromeda, which formed the subject of a drama of Euripides, and was also highly popular among artists and poets. The following is a brief account of this exploit:—Cassiopea, the wife of Cepheus, king of Æthiopia, ventured to extol her own beauty above that of the Nereids, who thereupon besought Poseidon to avenge them. He granted their request, and not only overwhelmed the land with disastrous floods, but sent also a terrible sea-monster, which devoured both man and beast. The oracle of Ammon declared that the land could only be saved by the sacrifice of the king’s daughter, Andromeda, to the monster. Cepheus, after some time, yielded to the entreaties of his people, and Andromeda was chained to a rock close to the sea. In this situation she was found by Perseus, on his return from his adventure with the Gorgons. He forthwith attacked and slew the sea-monster, and released the trembling maiden, who soon after married her preserver. Later writers, not satisfied with this adventure, added that Perseus was also obliged to vanquish a rival in Phineus, the king’s brother, to whom Andromeda had been already promised. Phineus, together with his warriors, was changed into stone by means of the Gorgon’s head.

The legend concludes with the return of the hero to Argos, where he was reconciled to his grandfather Acrisius, who had at first fled in terror to Larissa. On the occasion, however, of some games which the people of Larissa had instituted in his honour, Perseus was unfortunate enough to kill Acrisius with his discus, thus involuntarily fulfilling the prophecy of the oracle. In this feature of the story we recognise an unmistakeable reference to the symbolic meaning of Perseus; for the discus here represents, as in the story of the death of Hyacinthus, the face of the sun. Perseus, unwilling to enter on the inheritance of the grandfather he had slain, exchanged the kingdom of Argos for that of Tiryns, which was handed over to him by its king, Megapenthes, the son of Prœtus. He here founded the cities of Midea and Mycenæ, and became, through his children by Andromeda, the ancestor of many heroes, and, among others, of Heracles. His son Electryon became the father of Alcmene, whilst Amphitryon was descended from another of his sons. According to Pausanias, heroic honours were paid to Perseus, not only throughout Argos, but also in Athens and the island of Seriphus.

Perseus occupies a prominent position in Greek art. His common attributes are the winged sandals, the sickle which he made use of to slay Medusa, and the helmet of Hades. In bodily form, as well as in costume, he appears very like Hermes.

Among the art monuments which relate to his adventures is a marble relief from the Villa Pamfili, now in the Capitoline Museum at Rome, depicting the rescue of Andromeda. The sea-monster lies dead at the feet of Perseus, who is assisting the joyful Andromeda to descend from the rock. The attitude and expression of both figures are very striking: on the one side, maidenly modesty; on the other, proud self-reliance. It is worth remarking that Perseus, in addition to his winged shoes, has also wings on his head. The same conception is perceptible, with a few minor points of difference, in several Pompeian paintings, and on a marble relief of the Naples Museum (Fig. 56). Representations of Medusa are mostly confined to masks, which are often found on coats of mail, shields, leaves of folding doors, and instruments of all kinds. There are two types, representing an earlier and a later conception of Medusa. Earlier art set itself to depict the horrible only in the head of Medusa; and artists, therefore, strove to impart to the face as strong an expression of rage and ferocity as was possible, representing her with tongue lolling forth, and boar-like tusks. It is worthy of remark that, in the earlier examples of these masks—which are frequently met with on coins, gems, and pottery—the hair generally falls stiff and straight over the forehead, serving to render the horrible breadth of the face still more striking, while the snakes appear to be fastened round the neck like a necklace. Very different is the conception adopted by the later and more sensuous school. This laboured principally to give expression to the gradual ebbing away of life in the countenance of the dying Gorgon, an effect which was rendered still more striking by transforming the hideous Gorgon face of earlier times into an ideal of the most perfect beauty. The most splendid example of this later conception, which had been creeping in since the age of Praxiteles, is to be found in the Medusa Rondanini of the Munich collection—a marble mask of most beautiful workmanship, which was brought from the Rondanini Palace at Rome (Fig. 57). This Medusa, like many others of the later type, has wings on the head.

5. The Dioscuri.—On passing to Laconia and Messenia, the southern districts of the Peloponnesus, we come in contact with the legend of the Dioscuri. Tyndareüs and his brother Icarius were said to have founded the most ancient sovereignty in Lacedæmon. They were driven thence, however, by their half-brother Hippocoön, and were kindly received by Thestius, the ruler of the ancient city of Pleuron in Ætolia, who gave Tyndareüs his daughter Leda in marriage. Icarius received the hand of Polycaste, who bore him Penelope—afterwards the wife of Odysseus; while Leda was the mother of the Dioscuri, Castor and Polydeuces (Pollux). Tyndareüs was afterwards reinstated in his Lacedæmonian kingdom at Amyclæ by Heracles. Besides these two sons, Leda had also two daughters, Clytæmnestra and Helene (Helen), who are celebrated in connection with the Trojan war. An ancient legend also existed to the effect that Leda had been beloved by Zeus, who had approached her under the guise of a swan. The greatest incongruity prevails as to which of the children could claim a divine origin. In Homer, Helen alone is represented as the daughter of Zeus; while Clytæmnestra, together with Castor and Polydeuces, appear as the children of Tyndareüs. At a subsequent period, the name of “Dioscuri” (sons of Zeus) and a belief in their divine origin arose simultaneously. Later still, Castor was represented as a mortal, and the son of Tyndareüs; and Polydeuces as immortal, and the son of Zeus. After Castor, however, had fallen in the contest with the sons of Aphareus, his brother Polydeuces, unwilling to part from him, prevailed on Zeus to allow them to remain together, on condition of their spending one day in Olympus and the next in Hades. They thus led a life divided between mortality and immortality. The following is an account of their heroic deeds:—On attaining manhood, Castor distinguished himself by his skill in the management of horses; whilst Polydeuces became renowned as a skilful boxer, though he too had skill in riding. They first made war on Theseus, who had carried off their sister Helen, then ten years old, and set her free by the conquest of Aphidnæ. They next took part in the expedition of the Argonauts, in which Polydeuces gained still further renown by his victory with the cestus over the celebrated boxer Amycus. They were also present at the Calydonian boar hunt. Their last undertaking was the rape of the daughters of Leucippus, king of Messenia. This was the cause of their combat with their cousins Idas and Lynceus, the sons of Aphareus, to whom the damsels had been betrothed. According to others, however, it sprang from a quarrel as to the division of some booty that they had carried off together. Castor was slain by Idas, whereupon Polydeuces in his wrath slew Lynceus, while Idas himself was overwhelmed by a thunderbolt from Zeus.
