Traité de géométrie theorique et pratique, a l'usage des artistes
A 1764 Paris geometry textbook by Sébastien Le Clerc, revised by Chedel, Cochin and Jombert, written for artists and draughtsmen learning theoretical and practical geometry. Its pages are dense, justified letterpress text with numbered propositions, and its plates show compass-and-straightedge constructions, polygons and a crowded shop-like scene. A designer can take from them the clean geometric diagrams, labelled construction lines and the engraved plate layout as models for technical figures.
