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 :. | Annunciation | The last dinner | Unfinished painting of St. Jerome in the Wilderness | The Annunciation | The Last Supper |

Vincent Van Gogh
Dutch Post-Impressionist Painter, 1853-1890 Vincent Willem van Gogh (30 March 1853 ?C 29 July 1890) was a Dutch Post-Impressionist artist. Some of his paintings are now among the world's best known, most popular and expensive works of art. Van Gogh spent his early adult life working for a firm of art dealers. After a brief spell as a teacher, he became a missionary worker in a very poor mining region. He did not embark upon a career as an artist until 1880. Initially, Van Gogh worked only with sombre colours, until he encountered Impressionism and Neo-Impressionism in Paris. He incorporated their brighter colours and style of painting into a uniquely recognizable style, which was fully developed during the time he spent at Arles, France. He produced more than 2,000 works, including around 900 paintings and 1,100 drawings and sketches, during the last ten years of his life. Most of his best-known works were produced in the final two years of his life, during which time he cut off part of his left ear following a breakdown in his friendship with Paul Gauguin. After this he suffered recurrent bouts of mental illness, which led to his suicide. The central figure in Van Gogh's life was his brother Theo, who continually and selflessly provided financial support. Their lifelong friendship is documented in numerous letters they exchanged from August 1872 onwards. Van Gogh is a pioneer of what came to be known as Expressionism. He had an enormous influence on 20th century art, especially on the Fauves and German Expressionists.
