A 1640 German fortification treatise by Wilhelm Dilich, published in Hummen, presenting plans for bastioned defensive works for military engineers and builders. The plates are ground plans of star-shaped bastions, ramparts and ditches drawn in fine black line on cream paper, a useful reference for designers wanting geometric, angular layouts with layered outlines.
