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 Virgin and Child with St Anne ey | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | The Baptism of Christ | Grotesque profile of a man | Mona Lisa |

Heinrich von Angeli
1840 - 1925 Austrian painter. In 1853 he moved to Vienna to live with his uncle, who was a collector and a friend of the painters Friedrich von Amerling and Mathias Ranftl (1805-54). Angeli's early Self-portrait reflects the precocious maturity of his style, and in 1854 he enrolled at the Akademie der Bildenden K?nste in Vienna. In 1856, on the advice of Amerling, he went to study under Emanuel Gottlieb Leutze in D?sseldorf, where he executed one of his most significant history paintings, Mary Stuart Reading her Death Warrant (1857). In 1859 he moved to Munich, where he worked independently and was encouraged by Karl Theodor von Piloty, producing the history paintings Ludwig XI and Franz de Paula (1859) and Antony and Cleopatra for Ludwig I of Bavaria. In 1862 he again settled in Vienna, where he enjoyed increasing success. The life-size portrait of Baronin Seidler and the genre painting Avengers of Honour (1869), both exhibited at the Weltausstellung in Vienna in 1873, secured his reputation. After brief stays in Paris and Berlin (c. 1866), he went in 1871 to Italy, where he painted numerous portraits and the genre work Absolution Denied. His final genre paintings, Youthful Love (sold London, Sotheby's, 3 Oct 1980) and Calabrian Shepherd Couple, also date from this year. Henceforth he devoted himself entirely to portrait painting, receiving important commissions from such aristocratic circles as the Kinsky and Auersperg families (e.g. Graf Anton Alexander Auersperg, 1876; Vienna, Pr?sidium des Nationalrates). Whereas his early portraits were influenced by Amerling, Anton Einsle and 17th-century Dutch art, from the 1870s he developed his own elegant and restrained style. This helped him to obtain commissions at the courts of Vienna, St Petersburg and London
