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 :. | Studies of children | Mona Lisa | Madonna with the Yarnwinder (detail) dft | Virgin of the Rocks,completed (mk08) | Head of a girl |

Giuseppe Canella
(28 July 1788 - 11 September 1847), also referred to as Giuseppe Canella the Elder, was an Italian painter. Initially trained by his father Giovanni, an architect, fresco painter and set designer, Giuseppe Canella started out producing stage sets and decorating stately homes in Verona and Mantua. It may have been under the influence of Pietro Ronzoni, a landscape painter of international renown active in Verona, that he took up landscape. The first views were not produced until 1815, after a short stay in Venice. After making his debut at the Esposizione di Belle Arti di Brera of 1818, he made a long journey through Spain, the Netherlands and France for study purposes. The set of 13 landscapes shown at the Esposizione di Belle Arti di Brera in 1831 proved a great success with the public and critics alike, not least due to the fame achieved in Paris with works exhibited in the Salons, commissions from Louis Philippe of Orleans and the award of a gold medal in 1830. He returned to Milan in 1832 and devoted his energies to urban views characterised by an interest in the events of contemporary life and an atmospheric form of portrayal in evident competition with Giovanni Migliara. Landscape came to predominate as from 1835 with subjects drawn from the Lombard countryside and lakes. The focus on poor and humble aspects of life formed part of the artistes fundamental naturalism and coincided with a moralistic approach derived from the novelist Alessandro Manzoni. Crucial importance attaches in the artistes mature period to his trip to Rome and Naples in 1838-39.
