Pioero Della Francesca (c. 1420 Borge San Seplocto, near Arezzo-1492 Broge San Sepolcro0, born Piero de Benedetto dei Franceschi, was one of the most important painters of the early Renaissance and a pioneer of the art of rendering perspective. He lived in Florence between 1439 and 1442, where he worked together with Domenico Veneziano. It is from Veneziano's work, as well as from the innovations in perspective and colouration introduced by the other Florentine painters (in particular Andrea del Castagno), that Piero developed a new and earnest pictorial language. His paintings are characterized by the three-dimensional modeling of his figures and his mathematically precise construction of spatial depth. He also developed an innovative glazing technique that lent his works an atmospheric direct. Piero della Francesca did most of his work in his native city, but also carried out commissions in Ferrara, Arezzo, Rome, Urbino, and elsewhere. Important works by the artist include St. Herome with the Partron Grolamo Amdi, 1440-1450, Gallery, London; and The Adoration fo the Magi, after 1472?, the National Gallery, London.
