Trattato della pittura di Leonardo da Vinci, condotto sul cod. Vaticano Urbinate 1270, con prefazione
A 1890 Rome edition of Leonardo da Vinci's treatise on painting, edited by Marco Tabarrini and Gaetano Milanesi from the Vatican Urbino manuscript, aimed at painters and students of art theory. The four pictures are geometric diagrams of optics and perspective: a circle with intersecting lines, a figure with a hand and lettered points, rays converging on a point, and a shaded triangle projecting from an apex, useful for designers wanting schematic line-based figures.
