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 :. | Madonna with the Yarnwinder | Mona Lisa (detail) dhu | Details of Mona Lisa | Madonna of the Yarnwinder | Studies fur the adoration of the Konige |

Chandler Winthrop
American Colonial Era Painter, 1747-1790 American painter. He was one of ten children of William Chandler, a farmer, and Jemima Bradbury Chandler of Woodstock, CT. After the death of his father in 1754 and on reaching the age for apprenticeship, Chandler pursued a career as a portrait and ornamental painter. While there is no proof of his presence in Boston, the History of Woodstock (1862) states that he studied portrait painting there. He may also have had the opportunity to view works by the major artist of the city, John Singleton Copley, as well as those of his lesser-known contemporaries, William L. Johnston and Joseph Badger. In the course of his career, Chandler worked in such diverse trades as gilding, carving and illustrating, as well as portraiture, landscape and house painting, suggesting that he received some instruction as an artisan-painter.
BELLOTTO, Bernardo
Italian Rococo Era Painter, ca.1721-1780 Bernardo Bellotto (30 January 1720 ?C 17 October 1780) was an Italian urban landscape painter or vedutista, and printmaker in etching famous for his vedutes of European cities (Dresden, Vienna, Turin and Warsaw). He was the pupil and nephew of Canaletto and sometimes used the latter's illustrious name, signing himself as Bernardo Canaletto ?? fraudulently, according to some. Especially in Germany, paintings attributed to Canaletto may actually be by Bellotto rather than by his uncle; in Poland, they are by Bellotto, who is known there as "Canaletto". Bellotto's style was characterized by elaborate representation of architectural and natural vistas, and by the specific quality of each place's lighting. It is plausible that Bellotto, and other Venetian masters of vedute, may have used the camera obscura in order to achieve superior precision of urban views.
