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 of 1762, published in Paris by Briasson, David, and Le Breton, and intended as an illustrated companion to the French encyclopedia. The plates show trade tools and workshop machinery drawn in fine engraved line with lettered figure keys. A designer might take from them the clean technical diagram style, with numbered callouts and precise hatching for wood, metal, and mechanism.
