Dictionnaire raisonné de l'architecture française du XIe au XVIe siècle
A dictionary of French architecture from the eleventh to sixteenth centuries, written by architect Eugène-Emmanuel Viollet-le-Duc and published in Paris in 1854 for students and practising builders. Its pictures are numbered architectural sections, elevations and cutaway drawings of vaults, arches, buttresses and masonry walls, drawn in clean line with dimension marks, offering designers precise references for Gothic structure and proportion.
