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 :. | Virgin of the Rocks | Madonna in the rock grotto | Mona Lisa (mk45) | Grotesque profile of a man | St Jerome sgyu |

Jean-Pierre Franque
French, 1774-1860,French painter. He and his twin brother, Joseph-Boniface Franque (1774-1833), who was also a painter, were the sons of a modest farmer and, according to a local story, their youthful talent was such that the provincial government paid for them to study in Grenoble. They enrolled at the Ecole Gratuite in Grenoble and stayed for about two years (1786-8), training to become engravers. During the revolutionary period, the twins' education was taken over by the Departement de la Dreme. In 1792 their case was discussed at the National Assembly in Paris, which placed them in David's atelier and provided a pension for four years. David agreed to educate them but refused payment, writing to the President of the Assembly, 'I am overjoyed to be chosen to be the first teacher of these youths who could be called children of the nation since they owe everything to her.' The two brothers were considered very promising students, and David asked Jean-Pierre to assist him in the execution of the Intervention of the Sabine Women (1796-9; Paris, Louvre). Jean-Pierre also became involved with LES PRIMITIFS and the mysterious Maurice Quae (1779-1804), who reacted against Davidian principles and advocated a return to 'primitive' 15th-century Italian art. Franque demonstrated his independence from David in the selection of the subject for his 1806 Salon debut, the Dream of Love Induced by the Power of Harmony (destr.). In the spring of 1807 he was one of the 26 painters who entered a sketch (untraced) for the competition for a large painting representing Napoleon on the battlefield of Eylau, a competition won by Gros. In 1810 Franque produced Allegory of the Condition of France before the Return from Egypt (Paris, Louvre).
