De ui percussionis liber
De ui percussionis liber is a 1667 Latin treatise on the force of percussion, written by Giovanni Alfonso Borelli, a Italian physicist and mathematician, and printed in Bologna for scholars of mechanics. Its pictures are geometric diagrams in black line on white paper, with lettered points, arcs, pendulum-like circles and straight segments, plus numbered tables of figures that a designer could use for abstract line-work and schematic layouts.
