The library had been built two stories high, with a catwalk all around, halfway up, to afford access to the higher shelves, and its walls and the frescoed vault overhead had been generously arched with windows so that "Aunt Figgy" (short for Figuelotte, as Queen Sophie Charlotte was known to her family) and her bookish friends could read into the evening without need of candles. The high windows had been cracked open to let the room breathe in warm summer air and to exhale the smoke from the fizzing sparklers. The frescoes depicted the same assortment of Classical scenes that covered the ceiling of every rich person in Christendom nowadays, though the gods and goddesses had been provided with blond hair and blue eyes so that Jupiter might as well have been Wotan. Trompe l’oeil made it look as if the library had no ceiling but was open to the blue skies, and the gods were all springing out of frothy clouds. The writhing columns of smoke from the fireworks spread out against the plaster-work and swirled about to make the illusion that much better.
