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 :. | Study fur the head of a Madchens | Portrait de Mona Lisa dit La joconde | Portrait of Ginevra de Benci | Virgin of the Rocks | Madonna with the Yarnwinder ty |

John Opie
English Painter, 1761-1807,English painter. He was born in a tin-mining district, where his father was a mine carpenter. He had a natural talent for drawing and was taken up by an itinerant doctor, John Wolcot (the poet Peter Pindar, 1738-1819), who was an amateur artist and had a number of well-connected friends. Wolcot taught Opie the rudiments of drawing and painting, providing engravings for him to copy and gaining him access to country-house collections. Opie's early portraits, such as Dolly Pentreath (1777; St Michael's Mount, Cornwall, Lord St Levan priv. col.), are the work of a competent provincial painter and owe much to his study of engravings after portraits by Rembrandt. His attempts at chiaroscuro and impasto in Rembrandt's manner gave his pictures a maturity that clearly startled contemporary audiences expecting to see works by an untutored artist. Thus in 1780, when a picture by him was exhibited in London at the Society of Artists with the description 'a Boy's Head, an Instance of Genius, not having ever seen a picture', Opie was hailed as 'the Cornish Wonder'. When he himself arrived in London, where he was promoted by Wolcot and his paintings were exhibited at the Royal Academy in 1781 and 1782, he was seen as a phenomenon, impressing even Joshua Reynolds, who is reputed to have remarked that Opie was 'like Caravaggio and Velasquez in one'.
