Le operazioni del compasso geometrico, et militare
Le operazioni del compasso geometrico, et militare is a 1649 Padua treatise by Galileo Galilei, printed by P. Frambotto, on the geometric and military compass as a surveying and calculating instrument. Its pictures are plain line diagrams of triangles, sightlines and polygons with lettered vertices, drawn in simple black strokes that a designer could borrow for technical schematics or minimalist geometric patterns.
