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 Last Supper | Portrait | The Virgin and the Nino with Holy Ana | The last dinner | Madonna with a Flower (Madonna Benois) g |

VARIN, Quentin
French Painter, ca.1570-1634 French painter. He was the son of a shoemaker and from 1597 to 1600 was in the papal territory of Avignon, where he worked with a local painter, Pierre Duplan ( fl late 16th century), enrolling also in the local painters' guild. By 1607 he had returned to northern France, and he was married that year at Amiens. In 1612 he was working in the Norman village of Les Andelys, and there he became Nicolas Poussin's first master. For the Gothic church of Notre-Dame, Le Grand Andely, he produced in 1612 a Martyrdom of St Vincent, a Martyrdom of St Clarus and a Regina Coeli (all in situ), the works that provided Poussin with his first contact with contemporary painting. These are the earliest fixed points in Varin's oeuvre, although a ruined Rock of the Philosophers (Rouen, Mus. B.-A.), reminiscent of such late 16th-century French Mannerist painters as Antoine Caron,
Robert W. Weir
American Hudson River School Painter, 1803-1889,Painter and teacher. By his own account he was self-taught, with the exception of a few lessons from an unknown heraldic painter named Robert Cooke. However, after exhibiting a few works that were praised by the local press, he was sent to Italy by a group of New York and Philadelphia businessmen for further studies. There he trained with Florentine history painter Pietro Benvenuti. After three years in Europe (1824-7), he returned to New York, where he quickly became a mainstay of the artistic community. In 1831 he was elected to membership in the National Academy of Design in New York, and three years later he was made instructor of drawing at the US Military Academy in West Point, New York, a post he held for the next 42 years. Most scholars agree that he was more important as a teacher than as a painter. His best known work is the Embarkation of the Pilgrims (1837-43), which hangs in the Rotunda of the US Capitol Building in Washington, DC.
