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 :. | Buste one frontal to seeing man and head of a Lowen | Adoration of the Magi (mk08) | Kvinnoportratt | Funf studies of grotesque faces | Portrait de femme,dit a tort La belle ferronniere |

Jervis Mcentee
American Realist Painter, 1828-1891, He was an American painter of the Hudson River School. He is a somewhat lesser-known figure of the 19th century American art world, but was the close friend and traveling companion of several of the important Hudson River School artists. Aside from his paintings, McEntee's enduring legacy are the detailed journals he kept from the early 1870s until his death. In his writings McEntee records a detailed account of Hudson River School artists, their day-to-day life, gossip and personal reflections, and the overall arc of the American art world in the second half of the 19th century. He discusses his artistic successes and trials, particularly as money becomes more scarce with the decline in popularity of Hudson River School art. McEntee's journals are now kept by the Archives of American Art, a research center within the Smithsonian Institution. Five volumes of these diaries, from 1872 to 1890, have been digitally scanned, transcribed, and can be browsed in their entirety in the Jervis McEntee Diaries Online. McEntee was born in Rondout, New York on July 14, 1828. Little is known of his childhood. He exhibited his first painting at the National Academy of Design in New York City in 1850.
OCHTERVELT, Jacob
Dutch Baroque Era Painter, 1634-1682 Dutch painter. According to Houbraken, he and Pieter de Hooch were fellow students of the Dutch Italianate Nicolaes Berchem in Haarlem, probably between 1646, when Berchem returned from Italy, and 1655, when Ochtervelt married Dirkje Meesters in the Dutch Reformed Church in Rotterdam. Ochtervelt's earliest known works reveal the influences of a number of Dutch Italianate painters. Landscapes with figures, such as Hunters and Shepherds in a Landscape (1652; Karl-Marx-Stadt, St?dt. Kstsamml.), owe much to Berchem in subject and composition. They may also have been partly inspired by similar landscapes by Jan Baptist Weenix and Ludolf de Jongh. Towards the mid-1650s Ochtervelt began painting garden scenes
