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 Madonna of the Carnation (detail) dg | Cecila Gallerani (mk45) | Study fur the Sforza-Reiterstandbild | Last Supper | Buste one frontal to seeing man and head of a Lowen |

Garneray Ambroise
French Artist , Paris 1783-1857 French corsair, painter and writer. He served under Robert Surcouf and Jean-Marie Dutertre, and was held prisoner by the British for eight years. Garneray was born in Paris (on Rue Saint-Andre-des-arts, in the Latin Quarter) on February 9, 1783. He was the elder son of Jean-Francois Garneray (1755 - 1837), painter of the king, who was pupil of Jacques-Louis David. At thirteen, he joined the Navy as a seaman, encouraged by his cousin, Beaulieu-Leloup, commander of the frigate Forte ("the Stout one"). Garneray sailed from Rochefort to the Indian Ocean with the frigate division under Sercey, to which the Forte belonged. Garneray took part in the various campaigns of Sercey division and witnessed the hardship it met in the battle against Arrogant and Victorious. He then served in 1798 on the corvette Brule Gueule ("Mouth burner"), which patrolled with the frigate Preneuse ("the Taker"). Returning from this campaign, the Brule Gueule and Preneuse were chased by a British squadron comprising two ships of the line, one frigate and one corvette; the French flew into a creek near Black River whose shallow waters prevented the British from pursuing. The next day, the British squadron attacked; the French had established strong defensive positions by installing the unusable batteries of their ships ashore, and repelled the British squadron. In 1799,
Pierre de Valenciennes
Toulouse 1750-Paris 1819 .French painter. He trained at the academy in Toulouse under the history painter Jean-Baptiste Despax (1709-73). In 1769 he went to Italy for the first time, with Mathias Du Bourg, a councillor at the Toulouse parliament. Du Bourg introduced him to Etienne-Fran?ois, Duc de Choiseul, a keen patron of the arts, who in turn recommended him to Gabriel-Fran?ois Doyen, one of the leading history painters in Paris, whose studio he entered in 1773. Doyen gave his pupil a sense of the elevated ideals of history painting but was also sympathetic to the lesser genre of landscape. Valenciennes presumably frequented Choiseul's country seat at Chanteloup, near Amboise, meeting there the landscape painters Hubert Robert and Jean Hoeel, both proteg's of Choiseul. His early interest in the native landscape can be seen in his sketchbooks (Paris, Louvre), especially one dated 1775 that contains drawings made at Amboise, Compiegne and Fontainebleau
