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 :. | Funf studies of grotesque faces | Annunciation (detail) fg47 | St John the Baptist t | Saint jean-Baptiste | Madonna in the rock grottos(Details |

Jean Restout
French Neoclassical Painter, 1692-1768,was a French Neoclassical painter. Jean Restout was born in Rouen, the son of Jean Restout, the first of that name, and of Marie M. Jouvenet, sister and pupil of the then well-known Jean Jouvenet. In 1717, the Royal Academy having elected him a member on his work for the Grand Prix, he remained in Paris, instead of proceeding to Italy, exhibited at all the salons, and filled successively every post of academical distinction. His works, chiefly altar-pieces (Louvre Museum), ceilings and designs for Gobelin tapestries, were engraved by Cochin, Drevet and others; his diploma picture may still be seen at St Cloud. His son, Jean Bernard Restout (1732 - 1797),
LOTTO, Lorenzo
Italian High Renaissance Painter, ca.1480-1556 Italian painter and draughtsman. He had a long and often prosperous career as a painter, and, although he travelled widely, his style retained a close affinity with the paintings of his native Venice. He was one of an outstanding generation of painters, including Giorgione, Titian, Palma Vecchio and Pordenone, who appeared in Venice and the Veneto during the first decade of the 16th century. In comparison with his contemporaries, Lotto was a fairly traditional painter in that he worked primarily in the long-established genres of altarpieces, devotional pictures and portraiture. Such paintings were popular in the Venetian provinces and the Marches where Lotto spent much of his career and where he often received more money for his commissions than he could obtain in Venice. His most important commissions were for altarpieces, and he is perhaps best known for a series of sacre conversazioni in which he skilfully varied the symmetrical groupings of figures found in earlier Venetian treatments of the subject by Giovanni Bellini and Alvise Vivarini. Precedents in Venice were also important for Lotto's early efforts in bust-length portraiture, but from 1525 he made a considerable contribution to the development of the three-quarter-length portrait. He painted many private devotional paintings but only a few of the historical, mythological or allegorical scenes that were popular in northern Italy in this period. Lotto is one of the best-documented painters of the 16th century: 40 autograph letters dating from 1524 to 1539,
