The famous books on geometry written by Alain (Allain?) Manesson Mallet (1630–1706), published in the 1680s, set out various methods of marking geometrical layouts, seemingly in front of the famous new buildings of his day.
The château de Richelieu, the palace of Armand-Jean du Plessis, cardinal duc de Richelieu, is used several times as background to these illustrations. Below we show some of these pages culled from the web.
