So the young hero went by land and sea, still westwards, to the very borders of the world, where stands the giant of the west, Atlas, holding up the great vault of the skies on his broad shoulders. Beyond lay the dreary land of twilight, on the shores of the great ocean that goes round the world, and on the rocks on the shores sat the three old, old nymphs, the Graiæ, who had been born with grey hair, and had but one eye and one tooth among them, which they passed to one another in turn. When the first had seen the noble-looking youth speeding to them, she handed her eye on, that the next sister might look at him; but Perseus was

too quick—he caught the one eye out of her hand, and then told the three poor old nymphs that he did not want to hurt them, but that he must keep their eye till they had told him the way to Medusa the Gorgon.

They told him the way, and, moreover, they gave him a mist-cap helmet from Tartarus, which would make him invisible whenever he put it on, and also a bag, which he slung on his back; and, thus armed, he went further to the very bounds of the world, and he took his mirror in his hand, and looked into it. There he saw the three Gorgon sisters, their necks covered with scales like those of snakes (at least those of two), their teeth like boar’s tusks, their hands like brass, and their wings of gold; but they were all fast asleep, and Perseus, still looking into his mirror, cleft Medusa’s neck with his all-cutting sword, and put her head into the bag on his back without ever seeing her face. Her sisters awoke and darted after him; but he put on his helmet of mist, and they lost him, while he fled away on Mercury’s swift-winged sandals. As he sped eastward, he heard a voice asking whether he had really killed the Gorgon. It was Atlas, the old heaven-supporting giant; and when Perseus answered that he had, Atlas declared that he must see the head to convince him. So Perseus put a hand over his shoulder, and drew it up by its snaky hair; but no sooner had Atlas cast his eyes on it than he turned into a mountain, his white beard and hair becoming the snowy peak, and his garments the woods and forests. And there he still

stands on the west coast of Africa, and all our modern map-books are named after him.

But Perseus’ adventures were not over. As he flew on by the Lybian coast he heard a sound of wailing, and beheld a beautiful maiden chained by her hands and feet to a rock. He asked what had led her to this sad plight, and she answered that she was Andromeda, the daughter of Cepheus and Cassiopeia, king and

queen of Ethiopia, and that her mother had foolishly boasted that she was fairer than the Nereids, the fifty nymphs who are the spirits of the waves. Neptune was so much displeased that he sent a flood to overflow the land, and a sea-monster to devour the people and cattle. In an oasis or isle of fertility in the middle of the Lybian desert was a temple of Jupiter, there called Ammon, and the Ethiopians had sent there to ask what to do. The oracle replied that the evil should cease if Andromeda were given up to the monster. Cepheus had been obliged to yield her up because of the outcries of the people, and here she was waiting to be devoured. Perseus, of course, was ready. He heard the monster coming, bade Andromeda close her eyes, and then held up the Gorgon’s head. In an instant her foe had become a rock, and he cleft the maiden’s chains, brought her back to her father and mother, who gave her to him in marriage, and made a great feast; but here a former lover of hers insulted them both so much, that Perseus was forced to show him the Gorgon’s face, and turn him into stone.

Then Perseus, with Andromeda, took his way to Seriphos. Indeed it was high time that he should come back, for Polydectes, thinking that he must long ago have been turned into a rock at the sight of Medusa, had tried to take Danaë by force to be his wife, and she had fled into a temple, where no one dared to touch her, since it was always believed that the gods punished such as dragged suppliants away

from their temples. So Perseus went to Polydectes, who was in the midst of a feast, and, telling him that his bidding was done, held up the head of Medusa, and of course the king and his whole court turned at once into stone. Now that the work of the Gorgon’s head was done, Perseus offered it to Pallas, who placed it upon her shield, or, as it is always called, her ægis; and he gave back the sword of light, cap of mist, and winged sandals to Mercury.

After this he returned to Argos, and there, at a game of quoits, he had the misfortune to throw the quoit the wrong way, and hit his grandfather, the king, so as to kill him. Perseus reigned afterwards, and, like all the nobler Greek heroes, kept out the worship of Bacchus and its foul orgies from his dominions; but he afterwards exchanged kingdoms with another king, and built the city of Tiryas. He lived happily with Andromeda, and had a great many children, whose descendants viewed him as a demi-god, and had shrines to him, where they offered incense and sacrifice; for they thought that he and all the family were commemorated in the stars, and named the groups after them. You may find them all in the North. Andromeda is a great square, as if large stars marked the rivets of her chains on the rock; Perseus, a long curved cluster of bright stars, as if climbing up to deliver her; her mother Cassiopeia like a bright W, in which the Greeks traced a chair, where she sat with her back to the rest to punish her for her boast. Cepheus is there too, but he
