Dictionnaire raisonné de l'architecture française du XIe au XVIe siècle
Eugène-Emmanuel Viollet-le-Duc's illustrated dictionary of French architecture from the 11th to 16th centuries, published by B. Bance in Paris from 1858 for architects, restorers, and antiquarians. Wood-engraved plans, sections, and perspective details render vaults, flying buttresses, arch voussoirs, and mouldings in fine hatched line with scale bars and keyed letters, useful as precise structural line art.
