So they sailed past the Isle of Sciathos, with the Cape of Sepius on their left, and turned to the northward toward Pelion, up the long Magnesian shore. On their right hand was the open sea, and on their left old Pelion rose, while the clouds crawled round his dark pine forests, and his caps of summer snow. And their hearts yearned for the dear old mountain, as they thought of pleasant days gone by, and of the sports of their boyhood, and their hunting, and their schooling in the cave beneath the cliff. And at last Peleus spoke: "Let us land here, friends, and climb the dear old hill once more. We are going on a fearful journey: who knows if we shall see Pelion again? Let us go up to Cheiron our master, and ask his blessing ere we start. And I have a boy, too, with him, whom he trains as he trained me once, the son whom Thetis brought me, the silver-footed lady of the sea, whom I caught in the cave, and tamed her though she changed her shape seven times. For she changed, as I held her, into water, and to vapour, and to burning flame, and to a rock, and to a black-maned lion, and to a tall and stately tree. But I held her and held her ever till she took her own shape again, and led her to my father's house, and won her for my bride. And all the rulers of Olympus came to our wedding, and the heavens and the earth rejoiced together, when an immortal wedded mortal man. And now let me see my son; for it is not often I shall see him upon earth; famous he will be, but short lived, and die in the flower of youth." So Tiphys, the helmsman, steered them to the shore under the crags of Pelion; and they went up through the dark pine forests toward the Centaur's cave. And they came into the misty hall, beneath the snow-crowned crag; and saw the great Centaur lying with his huge limbs spread upon the rock; and beside him stood Achilles, the child whom no steel could wound, and played upon his harp right sweetly, while Cheiron watched and smiled.
