of the Sunken Castle," with the piteous tale of the spirits imprisoned;
and Simrock tells us in rhyme of the merman who sits waiting for a
mortal bride; while Wolfgang Müller sings of the "Castle under the
Lake," where at night ghostly torches are lighted and ghostly revels are
held, the story of which so fascinates the fisherman's boy who has heard
of these doings from his grandmother that as he watches the enchanted
waters one night his fancy plays him a cruel trick, and he plunges in to
