Trattato dell'arithmetica superiore ; [Trattato della trigonometria] ; [Trattato della meccanica]
This 1760 Italian treatise bundles three manuals on higher arithmetic, trigonometry and mechanics, compiled under the Burndy Library and held by the Smithsonian Libraries for students of the mathematical sciences. The first picture is a plate of numbered geometric diagrams of circles, chords, lines and labelled points, with a clean engraved line quality a designer could borrow for technical schematics. The second is a faint, cramped page of handwritten or sketched mechanical figures, pulleys and lettered notes, suggesting working drawings with a rough, hand-drawn texture.
