" He’d paused at the entrance and was, once again, staring down at the mosaic in the floor. Jostled and shoved by impatient guests, Armand stood his ground and contemplated the ancient symbol of Paris before it was Paris. Jacques had quoted the Latin motto. Fluctuat nec mergitur. Beaten by the waves, but never sinks. For the first time, despite seeing it for decades, Armand realized the mosaic looked like a scene from The Tempest. Shakespeare’s play opened with a terrible storm, and a ship in peril. As a young man leaped from a sinking ship to almost certain death, he screamed, “Hell is empty, and all the devils are here. "
