The Abbé Jean-Louis de Cordemoy (1655–1714) was a French architectural historian, prior of St-Nicolas at La-Ferté-sous-Jouarre (Seine-et-Marne), and a canon at St-Jean-des-Vignes, Soissons (Aisne). His Nouveau Traité de toute l’architecture was amongst the first studies of ecclesiastical architecture, wherein he praised the Gothic style for its clear expression of structure. Influenced by Michel de Frémin and Claude Perrault his ideas of ordonnance, disposition and bienséance as expressions of integrity to nature and structure were early precursors of the modern concepts of functionalism and truth to materials.[1] He had a considerable influence on 18th-century architectural theory, especially Antoine Desgodetz, Marc-Antoine Laugier, de la Hire and Boffrand. He also participated in an acrimonious debate with the engineer Amédée-François Frézier regarding sacred architecture in the Jesuit periodical Mémoires de Trévoux, a skirmish in the Quarrel of the Ancients and the Moderns.
