Traité de fortification souterraine : suivi de quatre mémoires sur les mines
A French military engineering treatise by Mouzé, published in 1804 in Paris, written for fortification and mining engineers. Its plates show plans of underground fortifications, mine galleries and sections of earthworks drawn in fine line with grey wash. A designer could take from them the precise geometric layouts of star-shaped bastions, angled ground plans and cross-hatched earth cuts as structural diagrams.
