"To Heracles, and to you, the rest of the Argonauts, I have a thing to say," said the ancient one, Nereus. "Know, first, that Hylas has been taken by the nymphs who love him and who think to win his love, and that he will stay forever with them in their cold and glimmering cave. For Hylas seek no more. And to you, Heracles, I will say this: Go aboard the Argo again; the ship will take you to where a great labor awaits you, and which, in accomplishing, you will work out the will of Zeus. You will know what this labor is when a spirit seizes on you." So the ancient one of the sea said, and he sank back beneath the waves. Heracles went aboard the Argo once more, and he took his place on the bench, the new oar in his hand. Sad he was to think that young Hylas who used to sit at his knee would never be there again. The breeze filled the sail, the Argonauts pulled at the oars, and in sadness they watched the island where young Hylas had been lost to them recede from their view. VII. KING PHINEUS Said Tiphys, the steersman: "If we could enter the Sea of Pontus, we could make our way across that sea to Colchis in a short time. But the passage into the Sea of Pontus is most perilous, and few mortals dare even to make approach to it." Said Jason, the chieftain of the host: "The dangers of the passage, Tiphys, we have spoken of, and it may be that we shall have to carry Argo overland to the Sea of Pontus. But You, Tiphys, have spoken of a wise king who is hereabouts, and who might help us to make the dangerous passage. Speak again to us, and tell us what the dangers of the passage are, and who the king is who may be able to help us to make these dangers less." Then said Tiphys, the steersman of the Argo: "No ship sailed by mortals has as yet gone through the passage that brings this sea into the Sea of Pontus. In the way are the rocks that mariners call The Clashers. These rocks are not fixed as rocks should be, but they rush one against the other, dashing up the sea, and crushing whatever may be between. Yea, if Argo were of iron, and if she were between these rocks when they met, she would be crushed to bits. I have sailed as far as that passage, but seeing The Clashers strike together I turned back my ship, and journeyed as far as the Sea of Pontus overland. "But I have been told of one who knows how a ship may be taken through the passage that The Clashers make so perilous. He who knows is a king hereabouts, Phineus, who has made himself as wise as the gods. To no one has Phineus told how the passage may be made, but knowing what high favor has been shown to us, the Argonauts, it may be that he will tell us." So Tiphys said, and Jason commanded him to steer the Argo toward the city where ruled Phineus, the wise king.
