The following is an excerpt from Louis-Sébastien Mercier's account of a typical day in eighteenth-century Paris (Evaluating the Evidence 18.2) : "Night falls; and, while scene-shifters set to work at the playhouses, swarms of other workmen, carpenters, masons and the like, make their way towards the poorer quarters. They leave white footprints from the plaster on their shoes, a trail that any eye can follow. They are off home, and to bed, at the hour which finds elegant ladies sitting down to their dressing-tables to prepare for the business of the night."
