Récréation mathématiques et physiques
Récréations mathématiques et physiques, a 1696 mathematical recreations book by Jacques Ozanam, published by Gallet and held by the ETH-Bibliothek, with numbered copperplate plates for readers of popular mathematics. The plates show geometric constructions: perspective grids, projections of spheres and circles, and angled diagrams with lettered points and dashed guide lines, set in plain black line on aged paper. A designer could draw on their precise, diagrammatic structure for geometric patterns, technical linework, or grid-based layouts.
