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 :. | The embryo in the Uterus | Madonna Litta (detail sdg | Waiter flat anatomy of the shoulder | Maria with Child and St. Anna | Mona Lisa (detail) dyk |

Jean-Martial Fredou
Jean-Martial Fredou (28 January 1710 e 1795) was a French painter known for his portraits. Born at Fontenay-Saint-Pere, Fredou was attached to the Cabinet du Roi housed in the Hôtel de la Surintendance at Versailles, where he was commissioned to render duplicates of official portraits of the French royal family painted by Jean-Marc Nattier, Maurice Quentin de La Tour, Louis-Michel Van Loo, Alexander Roslin or Joseph Siffred Duplessis. In his own commissions he often borrowed elements from the original works of these painters, for he was a deft portraitist himself. Between 1760 and 1762 the dauphine Marie-Josephe de Saxe, daughter-in-law of Louis XV commissioned informal portraits of herself and her children, for her own use. These portraits, whether in oil or drawn aux trois crayons, touched with pastels, have freshness and life. A modest commission came from the Dauphin and Dauphine in 1757: in 1748 they had earth brought in to the little courtyard of their private apartments at the château de Versailles, closed in with trelliswork, to make a little garden; and Fredou was commissiomed to paint two perspective panels to enlarge the little space.[1] Fredou was never made a member of the Academie Royale de Peinture et de Sculpture, but he was made First Painter to the comte de Provence in 1776 upon the death of François-Hubert Drouais.

Jean-Baptiste-Camille Corot
was a French landscape painter and printmaker in etching. Corot was the leading painter of the Barbizon school of France in the mid-nineteenth century. He is a pivotal figure in landscape painting and his vast output simultaneously references the Neo-Classical tradition and anticipates the plein-air innovations of Impressionism.
