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 :. | Woman portrait | Mona Lisa (mk45) | The Virgin and Child with St Anne | St Jerome sgyu | Portrat of Isabella d-Este |

Gabriel-Francois Doyen
(1726 - 5 June 1806) was a French painter, who was born at Paris. His passion for art prevailed over his father's wish, and he became in his twelfth year a pupil of Charles-Andra van Loo. Making rapid progress, he obtained at twenty the Grand Prix, and in 1748 set out for Rome. He studied the works of Annibale Carracci, Pietro Berrettini da Cortona, Giulio Romano and Michelangelo, then visited Naples, Venice, Bologna and other Italian cities, and in 1755 returned to Paris. At first unappreciated and disparaged, he resolved by one grand effort to achieve a reputation, and in 1758 he exhibited his Death of Virginia. It was completely successful, and procured him admission to the Acad??mie Royale de Peinture et de Sculpture. Among his greatest works are reckoned the Miracle des Ardents, painted for the church of St Genevieve at St Roch (1767)this painting was exhibited in the salon of 1767 which was recorded by Saint-Aubin in "View of the salon of 1767"; the Triumph of Thetis, for the chapel of the Invalides; and the Death of St Louis, for the chapel of the Military School. In 1776 he was appointed professor at the Academy. Soon after the beginning of the French Revolution he accepted the invitation of Catherine II of Russia. and settled at St Petersburg, where he was loaded with honors and rewards. He died there on 5 June 1806.
