Notes et croquis de géométrie : feuillets inédits, reproduits d'après les originaux conservés a la Bibliothèque du Chateau de Windsor
A 1901 Paris facsimile published by É. Rouveyre, reproducing unpublished geometry notes and sketches by Leonardo da Vinci from the Windsor Castle Library collection for a scholarly audience. The pages show dense handwritten Italian-style script beside geometric diagrams drawn in pen and ink on aged paper. A designer might take the interlocking circles, polyhedra and annotated construction lines as a model for technical diagram layouts, where sketchy notes sit around precise geometric figures.
