A 1616 German military engineering treatise by Buonaiuto Lorini, printed in Frankfurt with plates by Johann Theodor de Bry, written for fortification builders and artillery gunners. The pages are dense engraved plates of machines, measuring instruments, and siege works drawn in fine parallel line hatching with lettered keys, useful to a designer seeking old technical diagram vocabulary, precise linework, and schematic layouts.
