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 :. | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | Annunciation (detail) ey79 | Madonna in the rock grotto | Hi Hieronymus | Virgin of th Rock (mk08) |

James McDougal Hart
(May 10, 1828 - October 24, 1901), was a Scottish-born American landscape and cattle painter of the Hudson River School. His older brother, William Hart, was also a Hudson River School artist, and the two painted similar subjects. Hart was born in Kilmarnock, Scotland, and was taken to America with his family in early youth. In Albany, New York he trained with a sign and carriage maker possibly the same employer that had taken on his brother in his early career. Unlike his brother, however, James returned to Europe for serious artistic training. He studied in Munich, and was a pupil of Friedrich Wilhelm Schirmer in Dusseldorf. Hart returned to America in 1853. He exhibited his first work at the National Academy of Design in 1848, became an associate in 1857 and a full member in 1859. James Hart was particularly devoted to the National Academy, exhibiting there over a period of more than forty years, and serving as vice president late in his life from 1895 to 1899. Like his brother, James also exhibited at the Brooklyn Art Association (he lived for a time in Brooklyn) and at major exhibitions around the country. Along with most of the major landscape artists of the time, Hart based his operations in New York City and adopted the style of the Hudson River School. While James Hart and his brother William often painted similar landscape subjects, James may have been more inclined to paint exceptionally large works. An example is The Old Homestead (1862), 42 x 68 inches, in the collection of the High Museum of Art in Atlanta, Georgia. James may have been exposed to large paintings while studying in D??sseldorf, a center of realist art pedagogy that also shaped the practices of Albert Bierstadt and Worthington Whittredge. William Hart, who did not seek academic European training, seems to have been more comfortable painting small and mid-sized works. Like his brother William, James excelled at painting cattle. Kevin J. Avery writes, "the bovine subjects that once distinguished [his works] now seem the embodiment of Hart's artistic complacency." In contrast with the complacency of some of his cattle scenes, his major landscape paintings are considered important works of the Hudson River School.
