Piero della Francesca. Piero della Francesca, originally named Piero di Benedetto, was an Italian painter of the Early Renaissance.
   To contemporaries he was also known as a mathematician and geometer. Nowadays Piero della Francesca is chiefly appreciated for his art.
   His painting is characterized by its serene humanism, its use of geometric forms and perspective. His most famous work is the cycle of frescoes The History of the True Cross in the church of San Francesco in the Tuscan town of Arezzo.
   Piero was born Piero di Benedetto in the town of Borgo Santo Sepolcro, modern-day Tuscany, to Benedetto de' Franceschi, a tradesman, and Romana di Perino da Monterchi, members of the Florentine and Tuscan Franceschi noble family. His father died before his birth, and he was called Piero della Francesca after his mother, who supported his education in mathematics and art.
   He was most probably apprenticed to the local painter Antonio di Giovanni d'Anghiari, because in documents about payments it is noted that he was working with Antonio in 1432 and May 1438. He certainly took notice of the work of some of the Sienese artists active in San Sepolcro during his youth; e.g. Sassetta. In 1439 Piero received, together with Domenico Veneziano, payments for his work on frescoes for the church of Sant'Egidio in Florence, now lost. In Florence he must have met leading masters like Fra Angelico, Luca della Robbia, Donat
