Chiaroscuro, Astronomy, and the Universality of Painting
Drawing and light-and-shade spring from perspective, visual lines beget astronomy, and painting speaks to all.
This leaf completes the account of the three parts of perspective, naming the first—concerned only with the outlines of bodies—as drawing, from which springs the science of light and shade, or chiaroscuro. It observes that the science of visual lines gave birth to astronomy, a simple perspective of visual lines and cut pyramids. A chapter asking which science is most useful answers that painting is, because its end is communicable to every generation without interpreters of languages; even animals and infants respond to it, as when a dog, a cat and small children were drawn to an imitated painting. The running header reads 'PARTE'.

The first part of perspective is drawing
The part of perspective that extends only to the outlines and boundaries of bodies is called drawing, that is, the figuration of any body.
From drawing springs the science of light and shade
From drawing comes another science that extends to shadow and light—light and dark, or chiaroscuro—which is a science of great discourse.
Visual lines gave birth to astronomy
The science of the visual lines has given birth to the science of astronomy, which is a simple perspective, because it is all visual lines and cut pyramids.
Painting is the most communicable, hence most useful, science
Painting's end is communicable to all the generations of the universe and needs no interpreters of languages as letters do. It satisfies not only the human species but the other animals, as shown when a dog, a cat and swaddled children were drawn to an imitated painting.
