L'art de fortifier, de defendre, et d'attaquer les places : suivant les methodes françoises, hollandoises, italiennes & espagnoles, le tout enrichy de figures en taille douce
A 1677 Paris military engineering treatise by Claude-François Milliet Dechales, written for officers and engineers to teach fortification, defence and siege methods across French, Dutch, Italian and Spanish schools. Its pictures are small engraved plans of star-shaped bastions, ravelins and tenailles, drawn as flat outlines with hatched earthworks that a designer could take as a clear geometric pattern of angled zigzag forms.
