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 :. | Adoration of the Magi | Portrait of a Musician | Lady with Emine | Bacchus (mk05) | Pod of cherry and forest strawberry |

William Simpson
British Painter (1823-1899) was a British artist and war correspondent. Born into poverty in Glasgow on 28 October 1823, Simpson went on to become one of the leading 'special artists' of his day, and sketched many scenes of war for the Illustrated London News. His early years were very difficult living in a house with an abusive and alcoholic father, and in 1834 he was sent to live with his grandmother in Perth. Simpson's only formal schooling took place during this period and within a few years, he was working as an apprentice in the Glasgow lithographic firm of Macfarlane. The artist stated later that "this was the turning point which changed all my boyish intentions." It was during the years in Glasgow that he attended the Andersonian University and the Mechanics Institute in the evenings. His next position was with the lithographic company of Allan and Ferguson where he spent four years learning the trade. In 1851 Simpson moved to London where he was hired by Day & Sons. While at Day's he was able to work on several important lithographic sets. He became famous initially for his work in the Crimean War where he was sent by the firm of Colnaghi to create a series of watercolors suitable for lithographing. In the late 1850's he was sent to India to sketch scenes relating to the recent Sepoy Revolt. He joined the ILN in 1866 and covered the Abyssinian Campaign of 1868. In 1870 he went to France to sketch the war with Prussia, and in the following year observed the barricades of the Paris Commune. During a trip around the world, he stopped off in California and traveled to the Lava Beds area to report on the Modoc War in 1873. Five years later, he journeyed to Afghanistan to provide illustrations of the Second Afghan War that had broken out; he returned to London in the summer of 1879. In 1890, he observed the opening of the Forth Bridge and caught a chill which was to have detrimental effects on his health. He died at home in Willesden, north London, on August 17, 1899, and was buried in Highgate Cemetery. Besides his war pictures, he covered state events, coronations, funerals, and other ceremonies. He was particularly interested in India and sketched scenes of the Kashmir Maharajas.
