Das Buch von der Malerei nach dem Codex Vaticanus (Urbinas) 1270
A German edition of Leonardo da Vinci's treatise on painting, edited by Heinrich Ludwig and published in Vienna by W. Braumüller in 1882, working from the Codex Vaticanus Urbinas. The pages are text-and-diagram plates of perspective constructions, with geometric grids, converging sight lines drawn to a viewer's eye, and figure studies. A designer could take from them the clarity of early perspective diagrams, with orthogonals radiating from a single vanishing point over a ruled grid.
