Traité de la castrametation et de la défense des places fortes : où l'on propose de nouveaux ouvrages de fortification passagère pour les places assiégées & pour les camps retranchés ...
A French military treatise of 1771 by Joseph de Fallois, published in Berlin by G. J. Decker, setting out temporary fortifications and camp layouts for besieged towns and entrenched camps. Its plates are engineering drawings: a profile of a trench section with zigzag parapets, geometric tents and a pyramid-shaped shelter, rows of small square and triangular fortification blocks on a grid, and a plan of a river with a small symbol key of military earthworks, all in fine black line on pale paper, useful to a designer for technical diagram styling, grid layouts, and schematic map symbols.
