Far, far from land, where the waters are as blue as the petals of the cornflower and as clear as glass, there, where no anchor can reach the bottom, live the mer-people. […]
At the very deepest place, the mer-king has built his castle. […] Around the castle was a great park where there grew fiery-red and deep-blue trees. Their fruits shone as though they were the purest gold, their flowers were like flames, and their branches and leaves were ever in motion. The earth was the finest sand, not white but blue, the color of burning sulphur. There was a blue tinge to everything, down on the bottom of the sea. You could almost believe that you were suspended in mid-air and had the blue sky both above and below you. When the sea was calm, the sun appeared like a crimson flower, from which all light flowed.
