De vi percussionis liber
De vi percussionis liber is a 1667 Latin treatise on mechanics by Giovanni Alfonso Borelli, printed by the Iacobi Montii press, aimed at natural philosophers and scholars of the seventeenth century. Its pages are dense engraved diagrams of letter-labelled geometric figures, balances, circles, and lever-like apparatus arranged in numbered tables, with fine hatching and stippled shading. A designer might draw on the strict labelled grid, the scattered circles and arcs, and the hand-set typographic rhythm of the plates.
