Traité de méchanique
A French mechanics treatise from the early eighteenth century, catalogued by the Burndy Library and held by the Smithsonian Libraries, meant for students and practitioners of mechanics. Its pictures are plain engraved and ink-washed plates of geometric diagrams: pale flat shapes, a lever with weights, a ball on an incline, and pendulum-like suspended spheres with thin construction lines and lettered labels. A designer might take the spare, schematic diagram language, the tonal sphere shading, and the labelled line-drawing layout.
