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 Virgin of the Rocks | Reverse side of the portrait of Ginevra de' Benci | The Annunciation | Portrait of a Musician | Portrait of Ginevra de' Benci |

William Degouwe de Nuncques
(28 February 1867 - 1 March 1935) was a Belgian painter. He was born at Montherme, the Ardennes, France, of an old aristocratic family, After the Franco-Prussian war (1870-71), his parents settled in Belgium, and he taught himself to paint. In 1894 he married fellow artist Juliette Massin, who introduced him to the circle of Symbolist poets, who had a considerable influence on his style. He belonged to the avant-garde group Les XX and later exhibited at La Libre Esthetique. He travelled widely and painted views of Italy, Austria and France, often of parks at night. His best-known pictures, Pink House (1892), The Angels (1894), and Peacocks (1896), demonstrate the magical quality of his work. Pink House is thought to have been a major influence on Surrealism, especially the paintings of Rene Magritte. He is supposed to have said "To make a painting, all you need to do is to take some paints, draw some lines, and fill the rest up with feelings." A regular exhibitor in Paris, he was championed by Puvis de Chavannes and Maurice Denis. From 1900 to 1902 he and his wife lived in the Balearic Islands, where he painted the rugged coastline and the orange groves. After suffering a religious crisis around 1910, he painted pictures that revealed his tormented state of mind, and during World War I, while a refugee in the Netherlands, he produced only minor works. In 1919 he was overwhelmed by the death of his wife and lost the use of one hand. In 1930 he married the woman who had helped him through the crisis. They settled in Stavelot, where he spent his last few years painting snow-covered landscapes. The best collection of his paintings is in the Kröller-Meller Museum, Otterlo.
