L'architecture militaire, ou, La fortification nouuelle : augmentée et enrichie de forteresses regulieres, irregulieres, et de dehors : le tout a la practique moderne
Adam Freitag's 1668 treatise on military architecture, printed in Paris by Guillaume de Luyne, teaches fortification to engineers and officers in the modern practice of its day. Its engraved plates show star-shaped bastion plans, sloped earthwork profiles, and stacked fascine and gabion walls drawn with fine hatching and shadow. A designer could borrow the crisp geometric layouts and the dense line-engraved texture of its ground plans and cutaway perspectives.
