Dictionnaire raisonné de l'architecture française du XIe au XVIe siècle
A French architectural dictionary by Eugène-Emmanuel Viollet-le-Duc, published in Paris by A. Morel in 1875, covering French building from the 11th to the 16th century for architects and students. Its plates are measured engraved drawings of church sections, arches, and foundations, numbered and labelled with letters, with scale bars and plans. A designer could take from them the clean line hatching for masonry, the fine stone-course patterns, and the diagrammatic clarity of technical cutaways.
