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 :. | Portrat of Isabella d-Este | Funf studies of grotesque faces | Mona Lisa (La Gioconda) sdg | Equestrian monument | The Virgin and Child with St Anne |

Felix Vallotton
1865-1925was a Swiss painter and printmaker associated with Les Nabis. He was an important figure in the development of the modern woodcut. He was born into a conservative middle class family in Lausanne, and there he attended College Cantonal, graduating with a degree in classical studies in 1882. In that year he moved to Paris to study art under Jules Joseph Lefebvre and Gustave Boulanger at the Academie Julian. He spent many hours in the Louvre, where he greatly admired the works of Holbein, Derer and Ingres; these artists would remain exemplars for Vallotton throughout his life.[1] His earliest paintings, such as the Ingresque Portrait of Monsieur Ursenbach (1885), are firmly rooted in the academic tradition, and his self portrait of 1885 (seen at right) received an honorable mention at the Salon des artistes français in 1886. During the following decade Vallotton painted, wrote art criticism and made a number of prints. In 1891 he executed his first woodcut, a portrait of Paul Verlaine. The many woodcuts he produced during the 1890s were widely disseminated in periodicals and books in Europe as well as in the United States, and were recognized as radically innovative in printmaking. They established Vallotton as a leader in the revival of true woodcut as an artistic medium; in the western world, the relief print, in the form of commercial wood engraving, had long been mainly utilized unimaginatively as a medium for the reproduction of drawn or painted images and, latterly, photographs. Vallotton's starkly reductive woodcut style features large masses of undifferentiated black and areas of unmodulated white. While emphasizing outline and flat patterns, Vallotton generally made no use of the gradations and modeling traditionally produced by hatching. The influences of post-Impressionism, symbolism and the Japanese woodcut are apparent; a large exhibition of ukiyo-e prints had been presented at the École des Beaux-Arts in 1890, and Vallotton, like many artists of his era an enthusiast of Japonism, collected these prints. He depicted street crowds and demonstrations including several scenes of police attacking anarchists bathing women, portrait heads, and other subjects which he treated with a sardonic humor. His graphic art reached its highest development in Intimit's (Intimacies), a series of ten interiors published in 1898 by the Revue Blanche, which deal with tension between men and women. Vallotton's prints have been suggested as a significant influence on the graphic art of Edvard Munch, Aubrey Beardsley, and Ernst Ludwig Kirchner .By 1892 he was affiliated with Les Nabis, a group of young artists that included Pierre Bonnard, Ker-Xavier Roussel, Maurice Denis, and Edouard Vuillard, with whom Vallotton was to form a lifelong friendship. During the 1890s, when Vallotton was closely allied with the avant-garde, his paintings reflected the style of his woodcuts, with flat areas of color, hard edges, and simplification of detail.
