As he hurried over the sea with Medusa's head held firmly in his hand, some of the blood dripped down into the white-capped waves and was cherished by Neptune, who had once loved Medusa when she was a beautiful maiden. From these drops of blood the sea-king created the wonderful winged horse, Pegasus, who was to share in the adventures of another famous hero, Bellerophon. Some of the Gorgon's blood had also dropped on the hot African sand, as Perseus was flying upward from the Gorgon's cave, and from this sprang a brood of poisonous reptiles that ever afterward infested that region and brought death to many an unwary explorer.
The journey homeward was long and wearisome, and Perseus was often obliged to seek the seashore to rest. Once as he was flying along the coast of Africa, borne aloft on the winged sandals, he saw old Atlas standing where he had stood for many centuries with the weight of the heavens on his bent shoulders. The clouds wrapped his head so completely that Perseus could see only his immense body. Forests had grown up so high all around him that his huge legs were scarcely visible among the heavy foliage, and his broad shoulders looked like mighty bowlders rising up above the tree-tops. But though his head was so far in the clouds, Atlas knew that Perseus was approaching,—for giants have certain senses unpossessed by mortal men,—and he shook the clouds from about his face, and blew away the mists with his breath. Then, when the air was clear, and Perseus could see the white hair that was previously hidden above the clouds, he pitied poor Atlas for his heavy punishment and stopped to speak with him. The giant looked down from his great height and begged the hero to uncover Medusa's head,—which Perseus had kept wrapped in his cloak,—for he was anxious to gaze upon it and become himself an image of stone. He told how weary he was of standing for all these ages without ever being able to rest, and he could not endure the thought of keeping up this torture for eternity. So Perseus lifted up the Gorgon's head, being careful to keep his own averted, and Atlas gazed long and eagerly at the dead face, with its wreath of lifeless serpents. Then slowly the giant's great bulk began to harden, and the stooping shoulders became firm, unfeeling stone. As Perseus stood there watching the strange transformation, he seemed to see no longer the floating white hair of Atlas, but a pile of snow on a mountain top; and he looked no more on the huge limbs surrounded by forests, but he saw rents and clefts on a mountain side that just showed themselves through the thick trees. Thus was the burden of Atlas forever removed from his aching shoulders, and the heavens now rested securely on a mountain.
When Perseus resumed his journey along the coast, he soon came to a place where the cliffs rose abruptly from the sea; and as he looked down at the rocks below him, he saw, outlined against their dark surface, a figure that made him pause in his swift flight, and wonder if a sudden madness had taken hold on his fancy; for chained to the rock was a maiden so beautiful that even her constant weeping had not marred the perfect loveliness of her face. Keeping the Gorgon's head carefully concealed under his cloak, so that the captive maiden could get no glimpse of the snaky locks, Perseus flew to the girl's side, and, taking off his magic helmet, spoke to her gently. At any other time she would have been startled at this sudden appearance of a stranger; but the thought of her dreadful fate, so near at hand, drove all other fears from her mind. The spray from the sea dashed over her, and the cold winds blew on her shivering form; but of this she seemed to be hardly aware. Her eyes were fixed in wild terror upon a cavern in the rocks, where Perseus could see a huge dragon lying stretched out on the cool, slimy seaweed.
When the young hero spoke to the maiden, she did not seem to hear him, but, at his gentle persistence, she at last turned her eyes away from the dreaded cavern and told him her story. She said that her name was Andromeda, and that her mother, Cassiopeia,[87] had angered the sea-nymphs by presuming to rival them in beauty. To punish the queen for her vanity, the nymphs sent a fierce sea-monster to devastate the homes along the coast; and when the terrified people consulted an oracle to know how they might save themselves from further disaster, they were told that the monster would not depart until the Princess Andromeda was sacrificed to its fury. So the king, her father, and her wretched, remorseful mother, and a procession of weeping attendants had led her, that very day, to the rocks, and had chained her fast to await the monster's pleasure.
Just as Andromeda was speaking, there was a rustling sound in the cave, as if the dragon were stretching its huge wings. Then came a sudden whir and rush, as the monster glided out of the dim interior of its cave, and came speeding through the water toward its victim. The scaly hide glittered in the sunlight, and the great coils of its snaky body beat up the waves as it came with incredible swiftness toward the captive maiden, whose terrified shrieks almost unnerved the young hero who had come to rescue her. Quickly he donned his magic helmet and grasped the keen-edged sword that had already stood him in good stead. As the monster's head emerged from the waves, Perseus rushed upon it unseen, and with a quick thrust pierced the creature in its one vital spot. The dragon sank back into the blood-stained water, and then made a few ineffective plunges toward its victim; but Perseus's blow had been sure, and the creature's great body finally disappeared beneath the waves. While Andromeda was thanking her deliverer with grateful tears, he struck off the chains that bound her to the rock, and led her to where her parents and an astonished group of watchers had been looking on at the strange combat. The great joy of Andromeda's father was equaled only by the mother's happiness over her rescued child; and they both welcomed the young hero who had saved her from so terrible a fate.[88]
When Perseus had been entertained royally for several days, the king bade him demand any reward that he wished for his heroic services; and the youth boldly asked Andromeda's hand in marriage. To this the parents gladly consented, although she was already betrothed to her uncle Phineus, and the preparations were begun at once for the wedding. While the marriage celebrations were in progress, the jilted suitor, who had been too timid to attempt any rescue of Andromeda, now came forward to claim his wife. His pretensions were laughed at, however, and he left the court angry and plotting revenge. The following day he appeared with a band of followers and suddenly attacked Perseus, who had barely time to defend himself. The friends of the young hero rallied to his support, but they were outnumbered by the attacking party, and a disastrous battle might have ensued, had not Perseus bethought himself of a sure means of defense. Catching up the cloak in which he had wrapped the Gorgon's head, he cried: "Whoever is my friend, let him turn away his eyes." The courtiers of King Cepheus, and the men fighting around Perseus obeyed him; but Phineus and his followers believed this to be a mere trick to gain time, and looked on while Perseus unveiled Medusa's snaky head. Some of the gazers had their spears in uplifted hands; some were fitting arrows to their bows as they turned their eyes a moment toward Perseus; but in whatever position they stood, just so they were suddenly turned into stone. By some chance Phineus had been watching his men instead of looking at the Gorgon's head; and when he saw their dreadful transformation, he fell on his knees before Perseus, and with outstretched hands implored the hero to spare his life. But Perseus forced him to look upon the hideous face of Medusa, and he became a stone image with averted head and supplicating arms.
Having thus disposed effectively of his enemies, Perseus covered up his death-dealing trophy, and the wedding ceremonies were resumed. Later he departed with his bride to the country of Polydectes, where that king had been keeping his mother a prisoner until she would consent to marry him. He had long ago believed Perseus dead, and was therefore much astonished to see him appear unharmed and victorious. Hearing of the cruel treatment his mother had received from Polydectes, the young hero determined on a swift revenge. In the presence of the king and his court, he suddenly displayed the head of Medusa; and the whole company, just as they stood, were turned into stone. Then Perseus set sail with his wife and mother for his own country; but before he left he returned to Pluto the magic helmet, to Mercury the winged sandals, and to Minerva the wonderful Ægis. The august goddess of wisdom seemed to have taken a strange fancy to the Gorgon's head, so Perseus gave her this trophy of his victory, and she fixed it in the middle of her shield.
When Perseus, with Andromeda and Danaë, arrived in Argo, they found that old Acrisius had been driven from his throne, and that a usurper was enjoying the kingdom. It did not take long for the hero who had slain Medusa to kill the unlawful claimant, and reinstate his grandfather. The old man had been languishing for years in prison, and was hardly able to endure the great joy of his release at the hands of one whom he had long since believed to be dead. Things seemed to be settled very happily in spite of the oracle; but the decrees of the gods are sure to be fulfilled, and one day when Perseus was playing quoits, he accidentally threw one wide of the mark. It struck Acrisius, who was looking on at the game, and killed him instantly. This unfortunate mishap so preyed upon Perseus's mind that he could not remain in Argo, but exchanged his kingdom for that of Mycenæ, over which he ruled for many years very wisely and well. When at last Perseus died, the gods placed him among the stars with his wife Andromeda, and with Cassiopeia, who had long since been cured of her vanity.
