Vniversae geometriae, mixtaeqve mathematicae synopsis, et bini refractionvm demonstratarvm tractatvs
Mersenne's 1644 Paris synopsis of geometry and mathematics, printed by Antoine Bertier, is a learned mathematical treatise for scholars and students of the period. Its pictures are plain line diagrams of triangles, lines and lettered points, with dotted construction lines radiating from apexes, giving a designer clear examples of precise geometric structure and layered perspective-like overlays.
