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 :. | Buste one frontal to seeing man and head of a Lowen | Madonna in the rock grottos(Details | Portrait | Madonna Litta (detail sdg | the last supper |

Henri Gervex
French Academic Painter, 1852-1929.French painter. His artistic education began with the Prix de Rome winner Pierre Brisset (1810-90). He then studied under Alexandre Cabanel at the Ecole des Beaux-Arts in Paris, where his fellow pupils included Henri Regnault, Bastien-Lepage, Forain, Humbert (1842-1934) and Cormon; and also informally with Fromentin. Gervexs first Salon picture was a Sleeping Bather (untraced) in 1873: the nude, both in modern and mythological settings, was to remain one of his central artistic preoccupations. In 1876 he painted Autopsy in the H?tel-Dieu (ex-Limoges; untraced), the sort of medical group portrait he repeated in 1887 with his Dr Pean Demonstrating at the Saint-Louis Hospital his Discovery of the Hemostatic Clamp (Paris, Mus. Assist. Pub.), which celebrated the progress of medical science with a sober, quasi-photographic realism. Gervexs most controversial picture was Rolla (1878; Bordeaux, Mus. B.-A.), refused by the Salon of 1878 on grounds of indecency, partly because of the cast-off corset Degas had insisted he include. The painting shows the central character in a de Musset poem, Jacques Rolla, who, having dissipated his family inheritance, casts a final glance at the lovely sleeping form of the prostitute Marion before hurling himself out of the window. As his friend, Manet, had done the year before with his rejected Nana (1877; Hamburg, Ksthalle), Gervex exhibited his work in a commercial gallery, with great success.

Anton mauve
Dutch Painter, 1838-1888 He came from a large family of clergymen in the province of North Holland. At the age of 16 he was apprenticed to the animal painter Pieter Frederik van Os (1808-92): animals (especially sheep, but also cows and horses) became Mauve's preferred theme. He then trained for a few months with Wouterus Verschuur, who gave him his love of horses, in the style, at least, of Paulus Potter and Philips Wouwerman.
