Von dem Angrif und der Vertheidigung der Festungen
A German military treatise on the attack and defence of fortresses by Karl August von Struensee, published in 1774 by the David Siegert widow's press and held by the ETH-Bibliothek. Its folded plates show fortification plans, trench and bastion layouts, and cross-section diagrams drawn in fine black line on cream paper. A designer might draw on their crisp geometric star-shaped plans, angular rampart patterns and concentric ring diagrams for technical or map-like graphics.
