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 :. | Muscles and bone of leg and Hufte | Unfinished painting of St. Jerome in the Wilderness | St John in the Wilderness | Adoration of the Magi (mk08) | Anatomical study of the brain and the scalp |

Daniele Da Volterra
Italian Mannerist Painter and Sculptor, 1509-1566 Italian painter, stuccoist and sculptor. Much of the fascination of his career resides in the development of his style from provincial origins to a highly sophisticated manner, combining the most accomplished elements of the art of Michelangelo, Raphael and their Mannerist followers in a distinctive and highly original way. He provided an influential model for numerous later artists in Rome.
Musee national de la Marine
(National Navy Museum) is a maritime museum located in the Palais de Chaillot, Trocadero, in the XVIe arrondissement of Paris. It has annexes at Brest, Port-Louis, Rochefort (Musee National de la Marine de Rochefort), Toulon and Saint-Tropez. The permanent collection originates in a collection that dates back to Louis XV of France. In 1748, Henri-Louis Duhamel du Monceau offered a collection of models of ships and naval installations to Louis XV of France, with the request that the items be displayed at the Louvre and made available to students of the Naval engineers school, which Duhamel headed. The collection was put on display in 1752, in a room of the first floor, next to the Academy of Sciences; the room was called "Salle de Marine" (Navy room), and was used for teaching. With the French Revolution, the Salle de Marine closed in 1793. The collection was added to models owned by the King personally, to others owned by the Ministry of Navy, and yet others owned by emigres or executees (notably Philippe Égalite). A short-lived museum was opened between 1801 and 1803 at the Ministry of Navy, then located at Place de la Concorde.
