L' art de la fortification : appliqué a la défense des places de guerre d'un diamètre de six cents toises et au-dessus, par lequel on donne les moyens d'augmenter considérablement la force de résistance et de diminuer les frais de construction des grandes forteresses...
A fortification treatise by Ernst von Arenberg, printed in 1824 by Antoine Strauss, setting out methods for strengthening large fortresses and cutting their construction costs for military engineers. The plates show star-shaped bastion plans drawn in fine line with grey shading, plus section elevations and detail sheets that give a designer clear, geometric layouts of angular, interlocking forms.
