“I bade good-by to my sorrowful mother and I went from Seriphus—from that land that I might not return to without the Gorgon’s head. I traveled far from that country. One day I sat down in a lonely place and prayed to the gods that my strength might be equal to the will that now moved in me—the will to take the Gorgon’s head, and take from my name the shame of a broken promise, and win back to Seriphus to save my mother from the harshness of the king. “When I looked up I saw one standing before me. He was a youth, too, but I knew by the way he moved, and I knew by the brightness of his face and eyes, that he was of the immortals. I raised my hands in homage to him, and he came near me. ‘Perseus,’ he said, ‘if you have the courage to strive, the way to win the Gorgon’s head will be shown you.’ I said that I had the courage to strive, and he knew that I was making no boast. “He gave me this bright sickle-sword that I carry. He told me by what ways I might come near enough to the Gorgons without being turned into stone by their gaze. He told me how I might slay the one of the three Gorgons who was not immortal, and how, having slain her, I might take her head and flee without being torn to pieces by her sister Gorgons. “Then I knew that I should have to come on the Gorgons from the air. I knew that having slain the one that could be slain I should have to fly with the speed of the wind. And I knew that that speed even would not save me—I should have to be hidden in my flight. To win the head and save myself I would need three magic things—the shoes of flight and the magic pouch, and the dogskin cap of Hades that makes its wearer invisible. “The youth said: ‘The magic pouch and the shoes of flight and the dogskin cap of Hades are in the keeping of the nymphs whose dwelling place no mortal knows. I may not tell you where their dwelling place is. But from the Gray Ones, from the ancient daughters of Phorcys who live in a cave near where Atlas stands, you may learn where their dwelling place is.’ “Thereupon he told me how I might come to the Graiai, and how I might get them to tell me where you, the nymphs, had your dwelling. The one who spoke to me was Hermes, whose dwelling is on Olympus. By this sickle-sword that he gave me you will know that I speak the truth.” Perseus ceased speaking, and she who was the youngest and fairest of the nymphs came nearer to him. She knew that he spoke truthfully, and besides she had pity for the youth. “But we are the keepers of the magic treasures,” she said, “and some one whose need is greater even than yours may some time require them from us. But will you swear that you will bring the magic treasures back to us when you have slain the Gorgon and have taken her head?”
