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 :. | Profile one with book leaves gekroten of old man | Lorenzo de Medici between Antonio Pucci and Francesco Sassetti, with Giulio de Medici, fresco by Ghirlandaio | Virgin of the Rocks | Study fur the Sforza-Reiterstandbild | Kvinnoportratt |

Nathaniel Dance
English Painter, 1735-1811,Painter and politician, elder son of George Dance . He trained under Francis Hayman before travelling to Rome in 1754. As Nathaniel Dance he established himself as a portrait painter but was determined to succeed as a history painter. His picture the Death of Virginia (1759; untraced, but known from a sketch, London, Soane Mus.) is of documentary importance as the first dated Classical history painting by a British artist working in Rome. In 1762 Dance assisted Pompeo Girolamo Batoni, whose influence brightened his palette and introduced him to a grander clientele, including Edward Augustus, Duke of York (1739-67), who sat for both artists in 1764 (Dance's Edward Augustus, Duke of York, London, Buckingham Pal., Royal Col.). In the same year Dance painted a portrait of Angelica Kauffman (Burghley House, Cambs), with whom he was in love. He returned to London in 1765 and rapidly achieved fame as a portrait and history painter. His Timon of Athens (1767; London, Buckingham Pal., Royal Col.) was purchased by George III; but after the King appointed Benjamin West to be his history painter in 1772, Dance concentrated on portraits. He was among the 22 artists who successfully petitioned the King in 1768 to establish a Royal Academy, and he served for periods as a council member and visitor, until 1782. At the Academy's first exhibition (1769) Dance showed full-length portraits of George III and Queen Charlotte (Uppark, W. Sussex, NT); two years later he exhibited David Garrick as Richard III (Stratford-on-Avon, Town Hall). In the mid-1770s Dance became financially independent, and his output declined sharply, virtually ceasing after his marriage in 1783 to a wealthy widow. He resigned from the Academy in 1790 on his election as Member of Parliament for East Grinstead and subsequently only exhibited occasional landscapes as a 'gentleman'. In 1800 he was created a baronet and assumed the name of Dance-Holland; he died worth over
