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 :. | Study of the proportion of the head | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | Annunciation sgt66 | Holy Hieronymus | The Last Supper (detail) sg |

Martinus Rorbye
(17 May 1803 - 29 August 1848) was a Danish painter, known both for genre works and landscapes. He was a central figure of the Golden Age of Danish painting during the first half of the 19th century. The most traveled of the Danish Golden Age painters, he traveled both north to Norway and Sweden and south to Italy, Greece and Constantinople. He was also the first Danish painter to take to painting in Skagen at the northern top of Jutland, almost half a century before the thriving community of Skagen Painters formed and came to fame. Martinus Rørbye was born in Drammen in Norway to Danish parents Ferdinand Henrik Rørbye and his wife Frederikke Eleonore Catherine de Stockfleth. His father was a warehouse manager and later Superintendent of War, and had moved the family to Norway shortly before Martinus' birth. The family returned to Denmark when Martinus was 12 years old, shortly after the cession of Norway from Denmark in 1814. Martinus was not inclined to schooling, but in 1820 started his studies at the Royal Danish Academy of Fine Arts at 17 years of age. He studied under Christian August Lorentzen and Christoffer Wilhelm Eckersberg, a strong influence on a generation of artists during the Danish Golden Age. Rørbye was a favorite student of Eckersberg, and they formed a close association. He took to Eckersberges careful attention to nature and his strivings to capture details realistically. He was also greatly influenced by Lorentzenes use of color. He won the Academyes small silver medal in 1824, and the large silver medal in 1828. He competed for the gold medal and won a cash prize. In 1829 he won the small gold medal for his painting Christ healing the blind, which remains in the ownership of the Royal Danish Academy. He never won the large gold medal in spite of repeated attempts.
