Piero's deep interest in the theoretical study of perspective and his contemplative approach to his paintings are apparent in all his work.[15] In his youth, Piero was trained in mathematics, which most likely was for mercantilism.[16] Three treatises written by Piero have survived to the present day: Trattato d'Abaco (Abacus Treatise) [fr], Libellus de Quinque Corporibus Regularibus'' (''Short Book on the Five Regular Solids [fr])[c] and De Prospectiva pingendi (On Perspective in painting).[17] The subjects covered in these writings include arithmetic, algebra, geometry and innovative work in both solid geometry and perspective. Much of Piero's work was later absorbed into the writing of others, notably Luca Pacioli. Piero's work on solid geometry was translated in Pacioli's Divina proportione, a work illustrated by Leonardo da Vinci. Biographers of his patron Federico da Montefeltro of Urbino record that he was encouraged to pursue the interest in perspective which was shared by the Duke.
In the late 1450s, Piero copied and illustrated the following works of Archimedes:[18] On the Sphere and Cylinder, Measurement of a Circle, On Conoids and Spheroids, On Spirals, On the Equilibrium of Planes, The Quadrature of the Parabola, and The Sand Reckoner. The manuscript consists of 82 folio leaves, is held in the collection of the Biblioteca Riccardiana[19] and is a copy of the translation of the Archimedean corpus made by Italian humanist Iacopo da San Cassiano.
