Schema of an Ideal Fortress (Fortificatio)

This is a monochrome woodcut or engraving displaying a geometric, symmetrical fortress design. At the center is a small hexagon, which connects to a larger hexagonal inner ward, surrounded by a series of projecting arrow-shaped bastions. A water-filled moat separates the inner structure from the outer zigzagging defensive walls, with small bridges visible leading to the fortress gates. The lines are clean and precise, emphasizing the mathematical regularity and defensive capabilities of the structure.

This print illustrates the 'trace italienne' or star fort design, which became the standard in 17th-century European military architecture to counter the effectiveness of heavy artillery. It reflects the broader Early Modern obsession with geometry, order, and the application of mathematical principles to statecraft and natural philosophy.
