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, issued by A. Morel in Paris in 1875 for architects, restorers, and students of medieval building. The wood-engraved plates give measured elevations, sections, and perspective studies of capitals, bases, mouldings, vaults, and carved ornament, with hatched shading and dimension lines that supply clean line art for pattern work, borders, and architectural diagrams.
