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 :. | Ceiling decoration yy | Maria with Child and St. Anna | Profile of an old man | Last Supper | The Madonna of the Carnation g |

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.
Glackens, William James
American Ashcan School Painter, 1870-1938 American painter and illustrator. He graduated in 1889 from Central High School, Philadelphia, where he had known Albert C. Barnes, who later became a noted collector of modern art. He became a reporter-illustrator for the Philadelphia Record in 1891 and later for the Philadelphia Press. In 1892 he began to attend evening classes in drawing at the Pennsylvania Academy of Fine Arts, studying under Thomas Anshutz. In the same year he became a friend and follower of Robert Henri, who persuaded him to take up oil painting in 1894. Henri's other students, some of whom were referred to as the Ashcan school, included George Luks
Miller, Alfred Jacob
American Painter, 1810-1874 American painter. From 1831-2 he studied with the portrait painter Thomas Sully in Philadelphia, PA. In 1832 he went to France, where he studied in Paris at the Ecole des Beaux-Arts. He also visited Rome before returning to Baltimore, to open a portrait studio in 1834. Three years later Miller moved to New Orleans, LA, and was engaged by Captain William Drummond Stewart to accompany an expedition to the Rocky Mountains. The journey brought Miller into close contact with the American Indians, whose hunting and social customs he depicted in 200 watercolour sketches, and with the Far West fur trappers at their annual trading gatherings. He was one of the first artists to leave a detailed visual account of the life of the American mountain men (see WILD WEST AND FRONTIER ART). Miller's Rocky Mountain paintings are among the most romantic images of the American West ever created. His works are often panoramic and dramatic, yet he was equally adept at depicting charming, intimate scenes. His free, vigorous painting style brings to life both the American Indian and the rugged pioneer. Such paintings as the Lost Greenhorn
