" I should like to end this description of the stars with the Pleiades, which I once saw rising up out of the sea. When and where in Holland is the atmosphere ever so free from dust and mist that you can see the stars clearly right down to the horizon? One evening I saw a point of light appearing on the horizon, followed a moment later by another one. I thought they were the lights of a ship sailing by in the distance. But then a third light appeared, and a fourth, and finally there were seven altogether; it was then that I recognised the Pleiades, making for the heavens in full sail, like a ghost ship. "
