What is it in Venice that makes us feel we have been transported in time? Is it the ancient buildings and bridges, the palaces with their frescoes and the moss-lined canals? Is it the smooth-worn stones or the fountains of the piazze? Is it the stillness of the water and the echoing barcarole? No, it is rather the simple sound of voices and footsteps, heard, as if for the first time, in a city without engines, in a civilized world before the automobile.
