L'architecture militaire moderne, ou, Fortification : confirmée par diverses histoires tant anciennes que nouvelles, & enrichie des figures des principales forteresses qui sont en l'Europe
A 1648 Amsterdam fortification treatise by Matthias Dögen and Hélie Poirier, printed by Louys Elzevier in French for military engineers and readers of architecture, illustrated with engraved plates of European fortresses. The plates show precise line-engraved plans, bastions, ramparts and siege-works drawn in oblique aerial projection with careful hatching, offering a designer strong examples of geometric star-fort layouts, stepped earthworks and dense linear shading.
