This eternal "swowing of a flode" was the sound made by the circling stream of Oceanus, as he turns on his bed, washing the base of the White Rock, and the sands of the region of dreams. So we fleeted onwards till we came to marvellous lofty gates of black adamant, that rose before us like the steep side of a hill. On the left side of the gates we beheld a fountain flowing from beneath the roots of a white cypress-tree, and to this fountain my guide forbade me to draw near. "There is another yonder," he said, pointing to the right hand, "a stream of still water that issues from the Lake of Memory, and there are guards who keep that stream from the lips of the profane. Go to them and speak thus: 'I am the child of earth and of the starry sky, yet heavenly is my lineage, and this yourselves know right well. But I am perishing with thirst, so give me speedily of that still water which floweth forth of the mere of Memory.' And they will give thee to drink of that spring divine, and then shalt thou dwell with the heroes and the blessed." So I did as he said, and went before the guardians of the water. Now they were veiled, and their voices, when they answered me, seemed to come from far away. "Thou comest to the pure, from the pure," they said, "and thou art a suppliant of holy Persephone. Happy and most blessed art thou, advance to the reward of the crown desirable, and be no longer mortal, but divine." Then a darkness fell upon me, and lifted again like mist on the hills, and we found ourselves in the most beautiful place that can be conceived, a meadow of that short grass which grows on some shores beside the sea. There were large spaces of fine and solid turf, but, where the little streams flowed from the delicate-tinted distant mountains, there were narrow valleys full of all the flowers of a southern spring. Here grew narcissus and hyacinths, violets and creeping thyme, and crocus and the crimson rose, as they blossomed on the day when the milk-white bull carried off Europa. Beyond the level land beside the sea, between these coasts and the far-off hills, was a steep lonely rock, on which were set the shining temples of the Grecian faith. The blue seas that begirt the coasts were narrow, and ran like rivers between many islands not less fair than the country to which we were come, while other isles, each with its crest of clear-cut hills, lay westward, far away, and receding into the place of the sunset. Then I recognized the Fortunate Islands spoken of by Pindar, and the paradise of the Greeks. "Round these the ocean breezes blow and golden flowers are glowing, some from the land on trees of splendour, and some the water feedeth, with wreaths whereof they entwine their hands." {124} And, as Pindar says again, "for them shineth below the strength of the sun, while in our world it is night, and the space of crimson-flowered meadows before their city is full of the shade of frankincense-trees and of fruits of gold.
