In history as it is generally written, there are to be seen only great personages and events, kings, emperors, generals, ministers, wars, revolutions, treaties. When one closes a huge volume of history, one knows why this state made a great war upon that; understands the political thinking, the strategic plans, the diplomatic agreements of the powerful, but would hardly be able to answer much more simple questions: how people ate and drank, how the warriors, politicians, diplomats, were clad, and in general how men lived at any particular time.
