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 technical reference work for architects and students of building arts. Its engravings show masonry construction in close detail: an arch built of stacked voussoirs, a palace facade with rusticated courses and paired columns, a receding vault at a corner, and a restored crypto-portico. A designer could take from them the clean line-drawn rhythm of stone courses, arches and classical bays as a source for pattern and structure.
