Piero della Francesca, 1415-1492, was a painter of the Early Renaissance. Francesca painting was characterized by its serene humanism, its use of geometric forms and perspective. The most famous Francesca art is The Legend of the True Cross，which is in the church of San Francesco in the Tuscan town of Arezzo. His deep interest in the theoretical study of perspective and his contemplative approach to his paintings are apparent in all his work. -- The Copyright of Scripts is Reserved by Toperfect.
