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 :. | Mona Lisa | Portrat of Isabella d-Este | The Portinari Altarpiece | Madonna with a Flower (Madonna Benois) g | Profile of a man |

ROMNEY, George
English Painter, 1734-1802 The son of a cabinetmaker, George Romney was born in Dalton, Lancashire. He was apprenticed in 1755 to Christopher Steele, a provincial portrait painter, but was largely self-taught. Romney's ambition was to become a history painter. In 1762 he moved to London, where he studied the Duke of Richmond's collection of casts of antique sculpture and established himself as a portraitist. He went to Italy in 1773, and after his return in 1775 he became the favorite painter of high society. Morbidly sensitive and retiring, Romney kept aloof from the social world of his sitters and from the Royal Academy. By 1782 he was under the spell of Emma Hart, later Lady Hamilton and the mistress of Nelson, who sat for him as Circe, a Bacchante, Cassandra, the Pythian Priestess, Joan of Arc, St. Cecilia, Mary Magdalene, and other impersonations he suggested. In the 1780s he executed a number of Eton leaving portraits, which established him as the supreme interpreter of aristocratic adolescence in his age. For much of his life in London, Romney was under the wing of the poet William Hayley, who encouraged him in the choice of subjects from Milton and Shakespeare as well as the Bible and Greek tragedy. Romney's history paintings are today chiefly known from engravings, like the dramatic Tempest (1787-1790) commissioned for John Boydell's Shakespeare Gallery. A large number of drawings for these projects survive. Romney had married early in life an uneducated woman whom he did not bring to London but to whom he returned when his health finally gave way. Ill health and the facility with which he converted his early realistic style into a fashionable sketchlike formula for idealizing his sitters probably account for an unevenness of execution that has partially justified his critics. Unlike Joshua Reynolds, Romney did not enter into the character of his sitters, unless they possessed nervous traits like his own, for example, the moving portrait William Cowper. But he was psychologically involved with the generalized charms of youth, beauty, and breeding that he admired in his aristocratic sitters, and by combining a neoclassic purity of line with free but masterly brushwork he achieved a number of incomparable images which transcend the realism of portraiture.
