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 :. | The Virgin and St Anne (mk08) | La belle Ferronire dg | Madonna with the Yarnwinder | Virgin of the Rocks | Jacopo Bellini |

Alfred Sisley
French 1839-1899 Alfred Sisley Galleries Alfred Sisley (October 30, 1839 ?C January 29, 1899) was an English Impressionist landscape painter who was born and spent most of his life in France. Sisley is recognized as perhaps the most consistent of the Impressionists, never deviating into figure painting or finding that the movement did not fulfill his artistic needs. Sisley was born in Paris to affluent English parents; William Sisley was in the silk business, and his mother Felicia Sell was a cultivated music connoisseur. At the age of 18, Sisley was sent to London to study for a career in business, but he abandoned it after four years and returned to Paris. Beginning in 1862 he studied at the atelier of Swiss artist Marc-Charles-Gabriel Gleyre, where he became acquainted with Fr??d??ric Bazille, Claude Monet, and Pierre-Auguste Renoir. Together they would paint landscapes en plein air (in the open air) in order to realistically capture the transient effects of sunlight. This approach, innovative at the time, resulted in paintings more colorful and more broadly painted than the public was accustomed to seeing. Consequently, Sisley and his friends initially had few opportunities to exhibit or sell their work. Unlike some of his fellow students who suffered financial hardships, Sisley received an allowance from his father??until 1870, after which time he became increasingly poor. Sisley's student works are lost. His earliest known work, Lane near a Small Town is believed to have been painted around 1864. His first landscape paintings are sombre, coloured with dark browns, greens, and pale blues. They were often executed at Marly and Saint-Cloud.

Juriaen van Streeck
(1632 - 1687) was a Dutch Golden Age painter of still lifes. According to Houbraken, he was good at all sorts of still life subjects, including helmets, books, letters, musical instruments, and skulls or dead animals to indicate the transcience of life. He was a follower of Willem Kalf and influenced Barend van der Meer.Houbraken also wrote an entry for his son Hendrick van Streeck, who became a student of Emanuel de Witte and painted church interiors.
