Nor, although it was inhabited, could certain information be procured as to its internal construction. Those who dwelt in it often discovered rooms they had never entered before--yea, once or twice,--whole suites of apartments, of which only dim legends had been handed down from former times. Some of them expected to find, one day, secret places, filled with treasures of wondrous jewels; amongst which they hoped to light upon Solomon’s ring, which had for ages disappeared from the earth, but which had controlled the spirits, and the possession of which made a man simply what a man should be, the king of the world. Now and then, a narrow, winding stair, hitherto untrodden, would bring them forth on a new turret, whence new prospects of the circumjacent country were spread out before them. How many more of these there might be, or how much loftier, no one could tell. Nor could the foundations of the castle in the rock on which it was built be determined with the smallest approach to precision. Those of the family who had given themselves to exploring in that direction, found such a labyrinth of vaults and passages, and endless successions of down-going stairs, out of one underground space into a yet lower, that they came to the conclusion that at least the whole mountain was perforated and honeycombed in this fashion. They had a dim consciousness, too, of the presence, in those awful regions, of beings whom they could not comprehend. Once they came upon the brink of a great black gulf, in which the eye could see nothing but darkness: they recoiled with horror; for the conviction flashed upon them that that gulf went down into the very central spaces of the earth, of which they had hitherto been wandering only in the upper crust; nay, that the seething blackness before them had relations mysterious, and beyond human comprehension, with the far-off voids of space, into which the stars dare not enter. At the foot of the cliff whereon the castle stood, lay a deep lake, inaccessible save by a few avenues, being surrounded on all sides with precipices which made the water look very black, although it was pure as the nightsky. From a door in the castle, which was not to be otherwise entered, a broad flight of steps, cut in the rock, went down to the lake, and disappeared below its surface. Some thought the steps went to the very bottom of the water.
