On flew the Harpies, screeching and gnashing their teeth in anger and dismay, for now they felt that they might be driven from Salmydessus, where they had had such royal feasts. They rose high in the air and flew out toward the sea. But high as the Harpies rose, the sons of the North Wind rose higher. The Harpies cried pitiful cries as they flew on, but Zetes and Calais felt no pity for them, for they knew that these dread Snatchers, with the stains of blood upon their breasts and wings, had shown pity neither to Phineus nor to any other. On they flew until they came to the island that is called the Floating Island. There the Harpies sank down with wearied wings. Zetes and Calais were upon them now, and they would have cut them to pieces with their bright swords, if the messenger of Zeus, Iris, with the golden wings, had not come between. "Forbear to slay the Harpies, sons of Boreas," cried Iris warningly, "forbear to slay the Harpies that are the hounds of Zeus. Let them cower here and hide themselves, and I, who come from Zeus, will swear the oath that the gods most dread, that they will never again come to Salmydessus to trouble Phineus, the king." The heroes yielded to the words of Iris. She took the oath that the gods most dread--the oath by the Water of Styx--that never again would the Harpies show themselves to Phineus. Then Zetes and Calais turned back toward the city of Salmydessus. The island that they drove the Harpies to had been called the Floating Island, but thereafter it was called the Island of Turning. It was evening when they turned back, and all night long the Argonauts and King Phineus sat in the hall of the palace and awaited the return of Zetes and Calais, the sons of the North Wind. VIII. KING PHINEUS'S COUNSEL; THE LANDING IN LEMNOS They came into King Phineus's hall, their bright swords in their hands. The Argonauts crowded around them and King Phineus raised his head and stretched out his thin hands to them. And Zetes and Calais told their comrades and told the king how they had driven the Harpies down to the Floating Island, and how Iris, the messenger of Zeus, had sworn the great oath that was by the Water of Styx that never again would the Snatchers show themselves in the palace. Then a great golden cup brimming with wine was brought to the king. He stood holding it in his trembling hands, fearful even then that the Harpies would tear the cup out of his hands. He drank--long and deeply he drank--and the dread shapes of the Snatchers did not appear. Down amongst the heroes he came and he took into his the hands of Zetes and Calais, the sons of the North Wind. "O heroes greater than any kings," he said, "ye have delivered me from the terrible curse that the gods had sent upon me. I thank ye, and I thank ye all, heroes of the quest. And the thanks of Phineus will much avail you all."
