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 :. | Virgin of the Rocks | Annunciation | Portrats of two men | Annunciation (detail) dg | Madonna and Child |

Ludwig Knaus
German Painter, 1829-1910 was a German genre painter of the younger Desseldorf school. He was born at Wiesbaden and studied from 1845 to 1852 under Sohn and Schadow in Desseldorf. His early works, like "The Gamblers," in the Desseldorf Gallery, are in the manner of that school, being dark and heavy in color. This deficiency was remedied by study at Paris, whither he went in 1852 and enrolled as a pupil of Couture. In 1853 his "Morning after the Kermess" received the second gold Medal of the Salon and made him a celebrated painter. Except for a year's study in Italy he remained in Paris until 1860.New International Encyclopedia His chief works of this period include "The Golden Wedding," "The Baptism," and "The Promenade," purchased for the Luxembourg. From 1861 to 1866 he practiced at Berlin, producing such works as "Boys Playing Cards," "Looking for a Bride" (Wiesbaden Museum), and "His Highness on His Travels." The next eight years of his life saw the production of much of his best work, including "The Children's Festival" (Nation Gallery, Berlin), "In Great Distress," and "The Village Prince." From 1874 to 1883 he was professor at the Academy of Berlin, continuing to reside in that city until his death. Among the most importand works of his last period were: "The Holy Family" and "The Road to Ruin," both painted in 1876 and now in the Metropolitan Museum of Art, New York; "Behind the Curtain" (1880), Dresden Gallery; "The Rag Baby" (1880) and "A Village Festival" (1881), both in the Vanderbilt collection, Metropolitan Museum, New York; and "A Duel." During his last period Knaus also painted a series of "Idyls," with nudes in a rather classical style, of which an important example is in the Wiesbaden Museum.
