Architectura von Vestungen, wie die zu unsern Zeiten mögen erbawen werden ... Sampt den Grund Rissen, Visierungen, und Auffzügen für Augen gestellt
A 1589 German fortification treatise by Daniel Specklin, printed by Bernhart Jobin, with plans, elevations and cross-sections of star-shaped bastioned forts for military engineers and builders. The engraved plates are dense architectural diagrams of ground plans and sloped earthworks, useful to a designer for geometric layouts, hatched outlines and schematic line work.
