Hans Christian AndersenFar out in the ocean, where the water is as blue as the prettiest cornflower, and as clear as crystal, it is very, very deep; so deep, indeed, that no cable could fathom it: many church steeples, piled one upon another, would not reach from the ground beneath to the surface of the water above. There dwell the Sea King and his subjects.
