Leonhard Christoph Sturms Architectura militaris hypothetico-eclectica, oder Gründliche Anleitung zu der Kriegs-Baukunst : aus den Hypothesibus und Erfindungen der meisten und besten Ingenieurs dargestellet
A 1736 German military architecture treatise by Leonhard Christoph Sturm, published by Monath and compiled from the designs of many engineers as a practical guide to fortification-building. Its plates are engraved fortress plans, with bastions, ravelins and moats drawn in plan and in section, and each sheet is numbered and captioned in German. A designer could take from them the star-shaped geometry of bastion layouts, which reads as a strong radiating pattern for graphic or architectural diagrams.
