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 :. | Muscle structure of the thigh | The Virgin and Child with St Anne (detail) s | Head of a girl | St John in the Wilderness | Last Supper (mk08) |

James Northcote
RA (22 October 1746 - 13 July 1831), was an English painter was born at Plymouth, and was apprenticed to his father, a poor watchmaker. In his spare time, he drew and painted. In 1769 he left his father and set up as a portrait painter. Four years later he went to London and was admitted as a pupil into the studio and house of Sir Joshua Reynolds. At the same time he attended the Royal Academy schools. In 1775 he left Reynolds, and about two years later, having made some money by portrait painting back in Devon, he went to study in Italy. On his return to England, three years later, he revisited his native county, then settled in London, where John Opie and Henry Fuseli were his rivals. He was elected associate of the Academy in 1786, and full academician in the following spring. The "Young Princes murdered in the Tower," his first important work on a historical subject, dates from 1786, and it was followed by the "Burial of the Princes in the Tower". Both paintings, along with seven others, were intended for Boydell's Shakespeare Gallery. The "Death of Wat Tyler", now in the Guildhall, London, was exhibited in 1787; and shortly afterwards Northcote began a set of ten subjects, entitled "The Modest Girl and the Wanton", which were completed and engraved in 1796. Among the productions of Northcote's later years are the "Entombment" and the "Agony in the Garden," besides many portraits, and several animal subjects, such as "Leopards", "Dog and Heron", and "Lion".
