Italian High Renaissance Painter and Inventor, 1452-1519 Italian High Renaissance Painter and Inventor, 1452-1519 Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans for bridges, very light and strong, and plans for destroying those of the enemy. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, very convenient and easy of transport, designed to fire small stones, almost in the manner of hail??grape- or case-shot (see ammunition, artillery). He offered cannon of very beautiful and useful shapes, quite different from those in common use and, where it is not possible to employ cannon ?? catapults, mangonels and trabocchi and other engines of wonderful efficacy not in general use. And he said he made armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery ?? and behind them the infantry will be able to follow quite unharmed, and without any opposition. He also offered to design ships which can resist the fire of all the heaviest cannon, and powder and smoke. The large number of surviving drawings and notes on military art show that Leonardo claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum??a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful. Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: dual use technology. Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his Military Engineer General, although no known building by Leonardo exists. Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.   Related Paintings of LEONARDO da Vinci :. | Madonna Litta (detail sdg | Anatomical studies of the basin of the Steibeins and the lower Gliedmaben of a woman and study of the rotation of the arms | Waiter flat anatomy of the shoulder | Leda h | Portrat of a Madchens |

Ambrogio Lorenzetti
Italian Byzantine Style Painter, ca.1290-1348 Ambrogio Lorenzetti (or Ambruogio Laurati; c. 1290 ?C June 9, 1348) was an Italian painter of the Sienese school. He was active between approximately from 1317 to 1348. His elder brother was the painter Pietro Lorenzetti. His work shows the influence of Simone Martini, although more naturalistic. The earliest dated work of the Sienese painter is a Madonna and Child (1319, Museo Diocesano, San Casciano). His presence was documented in Florentine up until 1321. He would return there after spending a number of years in Siena. The frescoes on the walls of the Hall of the Nine (Sala dei Nove) or Hall of the Peace (Sala della Pace) in the Palazzo Pubblico of Siena are one of the masterworks of early renaissance secular painting. The "nine" was the oligarchal assembly of guild and monetary interests that governed the republic. Three walls are painted with frescoes consisting of a large assembly of allegorical figures of virtues in the Allegory of Good Government . In the other two facing panels, Ambrogio weaves panoramic visions of Effects of Good Government on Town and Country, and Allegory of Bad Government and its Effects on Town and Country (also called "Ill-governed Town and Country"). The better preserved "well-governed town and country" is an unrivaled pictorial encyclopedia of incidents in a peaceful medieval "borgo" and countryside. The first evidence of the existence of the hourglass can be found in one of his paintings. Like his brother, he is believed to have died of bubonic plague 1348. Giorgio Vasari includes a biography of Lorenzetti in his Lives.
