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 Annunciation | The muscles of Thorax and shoulders in a lebnden person | Salai as John the Baptist | anna sjalv tredje | Mona Lisa |

Giuseppe de nittis
Italian, 1846-1884 Italian painter, pastellist and printmaker. Throughout his career he was committed to a plein-air aesthetic and was particularly interested in rendering varying light effects, a concern that brought him into contact with the Impressionists. He was also acquainted with the members of the Macchiaioli, for whom his work was influential. In addition to oils, he experimented with printmaking and made innovative use of pastels. Practising a restrained, and therefore 'acceptable', form of Impressionism,
Worthington Whittredge
1820-1910 Thomas Worthington Whittredge (May 22, 1820 - February 25, 1910) was an American artist of the Hudson River School. Whittredge was a highly regarded artist of his time, and was friends with several leading Hudson River School artists including Albert Bierstadt and Sanford Robinson Gifford. He traveled widely and excelled at landscape painting, many examples of which are now in major museums. He served as president of the National Academy of Design from 1874 to 1875 and was a member of the selection committees for the 1876 Philadelphia Centennial Exposition and the 1878 Paris Exposition, both important venues for artists of the day. Whittredge was born in a log cabin near Springfield, Ohio in 1820. He painted landscapes and portraits as a young man in Cincinnati before traveling to Europe in 1849 to further his artistic training. Arriving in Germany he settled at the Dusseldorf Academy, a major art school of the period, and studied with Emanuel Leutze. At Dusseldorf, Whittredge befriended Bierstadt and posed for Leutze as both George Washington and a steersman in Leutze??s famous painting ??Washington Crossing the Delaware??, now in the collection of the Metropolitan Museum of Art in New York City. Whittredge spent nearly ten years in Europe, meeting and travelling with other important artists including Sanford Gifford. He returned to the United States in 1859 and settled in New York City where he launched his career as a landscape artist painting in the Hudson River School style. Whittredge journeyed across the Great Plains to the Rocky Mountains in 1865 with Sanford Gifford and John Frederick Kensett. The trip resulted in some of Whittredge??s most important works??unusually oblong, spare landscapes that captured the stark beauty and linear horizon of the Plains. Whittredge later wrote in his autobiography, ??I had never seen the plains or anything like them. They impressed me deeply. I cared more for them than for the mountains... Whoever crossed the plains at that period, not withstanding its herds of buffalo and flocks of antelope, its wild horses, deer and fleet rabbits, could hardly fail to be impressed with its vastness and silence and the appearance everywhere of an innocent, primitive existence." Whittredge moved to Summit, New Jersey, in 1880 where he continued to paint for the rest of his life. He died in 1910 at the age of 89 and is buried in the Springfield, New Jersey cemetery. Whittredge's paintings are now in the collections of numerous museums, including the Metropolitan Museum of Art in New York City and the Smithsonian American Art Museum in Washington, DC.
