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, based on the Codex Urbinas manuscript. The pictures are small geometric diagrams with lettered points, showing lines of sight, light rays, and the shadows cast by spheres and figures, useful for a designer studying perspective construction and cast shadow layouts.
