Dictionnaire raisonné d'architecture et des sciences et arts qui s'y rattachent
Ernest Bosc's Dictionnaire raisonné d'architecture, published in Paris by Firmin-Didot in 1877, is a French architectural reference dictionary written for students and practising architects. Its pictures are plain line engravings of building parts: a pierced stone window, a sectioned timber-roofed hall, a floor plan of the Pompeii forum, and a decorative band of interlocking ornament. A designer could take from them the clean, schematic drawing style of 19th-century technical documentation, with its hatching and labelled plans.
