Francesco di Giorgio Martini:
Italian Early Renaissance Painter and Sculptor, 1439-ca.1501
was an Italian painter of the Sienese School, a sculptor, an architect and theorist, and a military engineer who built almost seventy fortifications for the Duke of Urbino. Born in Siena, he apprenticed as a painter with Vecchietta. In panels painted for cassoni he departed from the traditional representations of joyful wedding processions in frieze-like formulas to express visions of ideal, symmetrical, vast and all but empty urban spaces rendered in perspective. Francesco di Giorgio is also known for architectural designs and sculptural work for Federico III da Montefeltro, Duke of Urbino, for whom he built star-shaped fortifications. He composed an architectural treatise Trattato di architettura, ingegneria e arte militare that he worked on for decades and finished sometime after 1482; china oil painting Francesco di Giorgio Martini Madonna del Terremoto
