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 :. | A rock gorge | virgin and child with st.anne | The Annunciation | anna sjalv tredje | Portrats of two men |

Johan Vilhelm Gertner
(10 March 1818 - 28 March 1871) was a Danish painter, best known for his portraiture. One of the last students of Christoffer Wilhelm Eckersberg, who was known as the father of the Golden Age of Danish Painting, Gertner belonged to the tail end of the Golden Age, a period during which Danish art moved towards a more realistic style, relying on inspiration both from French Realism and emerging photographic techniques. Gertner was born on 10 March 1818 to a craftsman at the Holmen naval base. He attended the Royal Danish Academy of Fine Arts from 1831 to 1837 where he was one of Christoffer Wilhelm Eckersberg, known as the farther of Goldn Age of Danish Painting. Eckersberg taught him a naturalistic approach to painting, but Gertner went much further with inspiration from French art and the emerging techniques of photography. His virtuosity in producing almost photographically precise portraits impressed many; in particular, his ability to reproduce textures and materials e crisp silk dresses, lustrous medals and jewellery, dark mahogany furniture, silky wallpapers, and soft carpets e won him much acclaim. Others, such as the influential art historian and critic Niels Lauritz Høyen, who opposed any foreign influence on Danish painting, disapproved of his style, preferring more sincere and sensitive portrayals. He was a professor at the Academy from 1858.
Antoni Brodowski
(26 December 1784 - 31 March 1832) was a Polish Neo-classicist painter and pedagogue. Brodowski was born in Warsaw but moved to Paris to study under Jean Augustin and Jacques-Louis David, later Brodowski's idol. He also became a pupil of Anne-Louis Girodet and Francois Gerard. His compositions are very large-scale with many figures, and often based on themes from Antiquity. Brodowski is also well-known for his decorative paintings within palaces and theatres in Warsaw.
