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 :. | Battle of Anghiari | You branching of the Blutgefabe, anatomical figure with heart kidneys and Blutgefaben | Portrait de Mona Lisa dit La joconde | Six studies fur naked or clothed men | Lady with the ermine |

Laurits Andersen Ring
Danish, 1854-1933 Laurits Andersen Ring (1854-1933) was one of the foremost painters of Danish symbolism. He was born as Laurits Andersen in the village Ring in southern Zealand. In 1881 he the took the name of his birth place, and was since known as L.A. Ring. For a while, he lived at Baldersbronde near Hedehusene in the old school building, which was later to be the home of another painter, Ludvig Find. Ring has produced several paintings from these towns. As a painter, he never distanced himself from his humble origin, but rather made it his dominant theme. Most of his paintings depict the village life and landscapes of southern Zealand from Præsto to Nestved. There are several examples of his work at practically every Danish art museum including the Hirschsprung Collection in Copenhagen. He was married on July 25, 1896 to fellow painter Sigrid Kahler, who was the daughter of ceramic artist Herman Kahler.
Cristobal Rojas
Cristobal Rojas (Cua, Miranda, 15 December 1857 e Caracas, 8 November 1890) was one of the most important and high-profile Venezuelan painters of the 19th century. Rojas's styles varied considerably throughout his life, and he displayed talents in painting that ranged primarily for dramatic effect, to works done in the Impressionist style. Cristebal Rojas Poleo was born in the city of Cea in the Valles del Tuy to parents who worked in the medical profession. Part of his childhood occurred during the middle of the federal war (1859 - 1863) and Cea was particularly affected by the events of the war. He initiated studies under his grandfather, Jose Luis Rojas, who taught him how to draw and motivated him to improve. At 13 years old, his father died and he was forced to begin work in a tobacco factory in Cea to help support his family. In 1878, an earthquake devastated the Valles del Tuy region, and the Rojas faced poverty. As a result he moved to Caracas where he continued his painting studies, despite again having to work in the tobacco industry to support his mother and family. In Caracas he attended classes by Jose Manuel Mauco at the Universidad Central de Venezuela. Between 1880 and 1882, he developed a keen interest in oils and displayed a primitive technique that would prevail in his later paintings such as Ruinas de Cea despues del Terremoto and Ruinas del templo de la Merced. During this time he became acquainted with the painter Antonio Herrera Toro, also coming under contract as Toro's assistant to paint Caracas Cathedral.
