Dictionnaire raisonné d'architecture et des sciences et arts qui s'y rattachent
A French architectural dictionary by Ernest Bosc, published in Paris in 1877 by Firmin-Didot for architects, builders and students of the building arts. Its figures are line engravings of construction details: a tracery window set in a round-arched frame, a row of pointed arches on corbels, a dome on pendentives with carved ornament, and carceres from a relief. A designer might take from them the geometry of medieval tracery, the rhythm of arcade bays, and the crisp hatching that renders stone and shadow.
