Piero della Francesca's treatise on perspective, De prospectiva pingendi, that is, 'On perspective for painting' is the first manual of drawing devoted to the new science of painters. With this fundamental text begins the great experience of Renaissance perspective, whose theoretical principles had been established by Leon Battista Alberti a few decades before. Its dissemination in the artists' workshops was entrusted to a series of handwritten codices, only seven of which, splendidly illustrated, have survived to our own day.
