Dictionnaire raisonné de l'architecture française du XIe au XVIe siècle
Eugène Viollet-le-Duc's multi-volume dictionary of French medieval architecture, published by Morel in Paris from 1858 for architects, restorers and antiquarians. Line engravings analyse capitals, mouldings, vault springings and carved foliage bands, combining shaded perspective views with lettered profile diagrams and plans; useful for ornament silhouettes, crisp hatching textures and annotated technical drawing conventions.
