Elémens de l'architecture militaire, à l'usage des cavaliers du Collège Royal Thérésien
A military engineering textbook by Johann Baptist Izzo, printed in Vienna in 1772 by Joseph Kurzböck for cavalry cadets at the Collège Royal Thérésien. Its plates are numbered engraved diagrams of fortifications, with bastions, ditches and glacis drawn in plan and in section. A designer could take from them the clean geometric logic of star-shaped layouts, with their angled outlines, hatched earthworks and numbered keys, useful for schematic line illustration and technical diagram styling.
