Piero della Francesca (1415 c.-1492)

The great artist from Borgo Sansepolcro is explicitly mentioned by Leonardo as «Maestro Piero del Borgo» among his bibliographical sources for the De Prospectiva pingendi. Leonardo was undoubtedly influenced by the painting and mathematical concepts of Piero, whose work was known to him through the cycles of frescoes and panel paintings.
In Tuscany, the Piero's works can be seen in Florence at the Uffizi, in Arezzo at the church of San Francesco, at Monterchi and in the Museum of Sansepolcro.
