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 :. | La belle Ferronire dg | Portrat of a musician | Gekrose of the intestine and its Gefabsystems | Portrait of Ginevra de Benci | Grotesque profile of a man |

Charles conder
English-born Australian Painter, 1868-1909 English painter, active in Australia and France. He was sent to Australia in 1884 to learn surveying under his uncle W. J. Conder. After about two years in survey camps, he attended evening classes at the Royal Art Society, Sydney; in 1887 he worked as a lithographic draughtsman for the Illustrated Sydney News. Tom Roberts, then in Sydney on a visit from Melbourne, was among the open-air landscape painters that he knew at this time. He taught Conder some of the principles of Impressionism, such as truth to the momentary effect of light and to colour values, and the rejection of the academic ideal of high finish. The most important painting of Conder's Sydney years, the Departure of the 'SS Orient' from Circular Quay, 1888 (1888; Sydney, A.G. NSW), already showed a distinct personal style, combining humour with nostalgia and selective observation with decorative finesse of handling and design. In December 1888 Conder joined Roberts and Arthur Streeton in Melbourne. During the following summers they painted together at the outer suburbs of Mentone, Box Hill and Eaglemont
Kane Paul
Irish-born Canadian Painter b.1810 d.1871 was an Irish-Canadian painter, famous for his paintings of First Nations peoples in the Canadian West and other Native Americans in the Oregon Country. A largely self-educated artist, Kane grew up in Toronto (then known as York) and trained himself by copying European masters on a study trip through Europe. He undertook two voyages through the wild Canadian northwest in 1845 and from 1846 to 1848. The first trip took him from Toronto to Sault Ste. Marie and back. Having secured the support of the Hudson's Bay Company, he set out on a second, much longer voyage from Toronto across the Rocky Mountains to Fort Vancouver and Fort Victoria in the Columbia District, as the Canadians called the Oregon Country. On both trips Kane sketched and painted Aboriginal peoples and documented their lives. Upon his return to Toronto, he produced more than one hundred oil paintings from these sketches. Kane's work, particularly his field sketches, are still a valuable resource for ethnologists.
