Dictionnaire raisonné de l'architecture française du XIe au XVIe siècle
A reference dictionary of French architecture from the 11th to 16th centuries, written by architect Eugène-Emmanuel Viollet-le-Duc and published in Paris in 1858 for students and builders. Its plates are measured technical drawings: flat elevations and sections of masonry, a Gothic window with traceried rose and ribbed vaulting, and scrolled wrought-iron railings with labelled details. A designer could draw on their crisp line hatching for stonework textures and the clean scroll motifs of the ironwork.
