Architectura von Vestungen : wie ein jeder Platz auff ein neue Art zubevestnen ...
A 1651 German fortification treatise by Johann Ardüser, published by Johann Heinrich Hamberger, presenting new methods for fortifying any town site with plans and construction diagrams. Its pictures are precise engraved plans, geometric layouts and cutaway views of star-shaped bastions and ditches, with handwritten annotations on some sheets; a designer might draw on their clean line structure, radiating construction arcs and layered geometric star forms.
