THE PALACE IS AS LARGE as a good-sized town, for through the centuries its outbuildings, its lodges, its guest houses, the mansions of its lords and ladies in waiting have been linked by covered ways, and those covered ways roofed, in turn, so that here and there we find corridors within corridors, like conduits in a tunnel, houses within rooms, those rooms within castles, those castles within artificial caverns, the whole roofed again with tiles of gold and platinum and silver, marble and mother-of-pearl, so that the palace glares with a thousand colours in the sunlight, shimmers constantly in the moonlight, its walls appearing to undulate, its roofs to rise and fall like a glamorous tide, its towers and minarets lifting like the masts and hulks of sinking ships.
