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 :. | Annunciation sgt66 | Madonna with the Yarnwinder tw | The Madonna of the Carnation (detail) sg | Profile of an old man | Adoration of the Magi (mk08) |

Hitchcock, George
American Painter, 1850-1913 American painter, active in the Netherlands. A descendant of Roger Williams (the founder of Rhode Island), he practised law for several years in New York before deciding in 1879 to become an artist. He studied in Paris with Gustave Boulanger and Jules Lefebvre, in D?sseldorf, and in The Hague with H. W. Mesdag. He settled in Egmond-aan-Zee, near Alkmaar, in 1883, and was soon widely known for his paintings of religious subjects in contemporary settings and of sunlit views of tulip fields. He returned to the USA only occasionally in later years. Hitchcock's style, similar to Impressionism, has been appreciated more in Europe than in the USA. A good example of his style is the Blessed Mother (1892; Cleveland, OH, Mus. A.). He received some recognition in the USA, such as election to associate membership in the National Academy of Design, New York,
Martin Johnson Heade
American Hudson River School Painter, 1819-1904 Martin Johnson Heade (August 11, 1819-September 4, 1904) was a prolific American painter known for his salt marsh landscapes, seascapes, portraits of tropical birds, and still lifes. His painting style and subject matter, while derived from the romanticism of the time, is regarded by art historians as a significant departure from that of his peers. Art historians have come to disagree with the common view that Heade is a Hudson River School painter, a view given wide currency by Heade's inclusion in a landmark exhibition of Hudson River School landscapes at the Metropolitan Museum of Art in 1987. The leading Heade scholar and author of Heade's catalogue raisonn??, Theodore E. Stebbins, Jr., wrote some years after the 1987 Hudson River School exhibition that "...other scholars??myself included??have increasingly come to doubt that Heade is most usefully seen as standing within that school." According to the Heade catalogue raisonn??, only around 40 percent of his paintings were landscapes. The remaining majority were still lifes, paintings of birds, and portraits, subjects unrelated to the Hudson River School. Of Heade's landscapes, perhaps only 25 percent were painted of traditional Hudson River School subject matter. Heade had less interest in topographically accurate views than the Hudson River painters, and instead focused on mood and the effects of light. Stebbins writes, "If the paintings of the shore as well as the more conventional compositions...might lead one to think of Heade as a Hudson River School painter, the [marsh scenes] make it clear that he was not."
