Dictionnaire raisonné de l'architecture française du XIe au XVIe siècle
Eugène-Emmanuel Viollet-le-Duc's alphabetical dictionary of French medieval architecture, published by A. Morel in Paris in 1875 for architects, restorers and students. Line engravings give measured elevations, vault plans with radiating ribs, sections through piers and buttresses, and details of capitals, mouldings and window arches, with lettered keys and dimension lines usable as diagrammatic and ornamental stock.
