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 :. | La Belle Ferronniere | Bacchus (mk05) | Virgin and Child with St Anne and St John the Baptist | Virgin of the Rocks (mk10) | The Annunciation |

Otto Muller
1874-1930 was a German painter and printmaker of the Die Br??cke expressionist movement. Otto Mueller was born in Liebau (now Lubawka, Kamienna G??ra County), Kreis Landeshut, German Silesia. Between 1890-1892 he was trained in lithography in Görlitz and Breslau. From 1894 to 1896 he studied at the Academy of Fine Arts in Dresden and continued his study in Munich 1898. He left Munich's academy after Franz von Stuck classified him as untalented. His early works are influenced by impressionism, Jugendstil and symbolism. When he settled to Berlin in 1908, he turned more and more to the expressionism. During this time there were meetings with Wilhelm Lehmbruck, Rainer Maria Rilke and Erich Heckel. In 1910, he joined 'Die Br??cke', a Dresden-based group of Expressionist artists. He was member of the group until it disbanded in 1913 due to artistic differences. At the same time Mueller also had contact with the artists group of the 'Blaue Reiter'. During the World War I he fought as a German soldier in France and Russia. After the war he became professor at the academy of arts (Akademie der Bildenden Kunste) in Breslau where he taught until his death on September 24, 1930. Johnny Friedlaender and Isidor Ascheim were among his pupils there. Altogether his printmaking amounted to 172 prints, in woodcut, etching and lithography. In 1937 the Nazis seized 357 of his works from German museums, since the pictures were considered as degenerate art. Mueller was one of the most lyrical of German expressionist painters. The central topic in Mueller's works is the unity of humans and nature, whereas his paintings are focused on a harmonious simplification of form, colour and contours.
