Recueil de planches, sur les sciences, les arts libéraux, et les arts méchaniques : avec leur explication ..
This is a plate volume from Diderot and d'Alembert's Recueil de planches, published in Paris in 1762 by the Briasson, David, Le Breton and Durand partnership for readers of the French encyclopedia. The engraved plates show technical machinery and workshop structures drawn in precise line with lettered reference keys. A designer could take from them the clean, diagrammatic linework, hatched shading on timber frames, and the schematic way mechanisms are laid out flat on the page.
