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 :. | Study Fur the Trivulzio-monument | Profile of a child | Portrats of two men | Mona Lisa (detail) dyk | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici |

Asher Brown Durand
1796-1886 Asher Brown Durand Galleries His interest shifted from engraving to oil painting around 1830 with the encouragement of his patron, Luman Reed. In 1837, he accompanied his friend Thomas Cole on a sketching expedition to Schroon Lake in the Adirondacks and soon after he began to concentrate on landscape painting. He spent summers sketching in the Catskills, Adirondacks, and the White Mountains of New Hampshire, making hundreds of drawings and oil sketches that were later incorporated into finished academy pieces which helped to define the Hudson River School. Durand is particularly remembered for his detailed portrayals of trees, rocks, and foliage. He was an advocate for drawing directly from nature with as much realism as possible. Durand wrote, "Let [the artist] scrupulously accept whatever [nature] presents him until he shall, in a degree, have become intimate with her infinity...never let him profane her sacredness by a willful departure from truth." Like other Hudson River School artists, Durand also believed that nature was an ineffable manifestation of God. He expressed this sentiment and his general views on art in his "Letters on Landscape Painting" in The Crayon, a mid-19th century New York art periodical. Wrote Durand, "[T]he true province of Landscape Art is the representation of the work of God in the visible creation..." Durand is noted for his 1849 painting Kindred Spirits which shows fellow Hudson River School artist Thomas Cole and poet William Cullen Bryant in a Catskills landscape. This was painted as a tribute to Cole upon his death in 1848. The painting, donated by Bryant's daughter Julia to the New York Public Library in 1904, was sold by the library through Sotheby's at an auction in May 2005 to Alice Walton for a purported $35 million. The sale was conducted as a sealed, first bid auction, so the actual sales price is not known. At $35 million, however, it would be a record price paid for an American painting at the time.
