Della fortificatione delle città
A 1564 Venetian treatise on fortification by Girolamo Maggi and Jacomo Castriotto, printed in Venice for an audience of military engineers and city builders. Its pages are technical diagrams of bastions, walls, and siege defences drawn in ruled line work, with lettered plans and perspective views of earthworks and masonry. A designer could take from them the clean geometry of angled star-shaped ramparts, the layered section views of walls, and the plan-and-elevation layout of defensive structures.
