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 :. | Rule fur the proportion of the human figure | Muscle structure of the thigh | Madonna with the Yarnwinder | Virgin and Child with St Anne and St John the Baptist (mk08) | Lady with Ermine |

Joseph Raphael
1869-1950 Joseph Morris Raphael holds a high place in the California, American and French Schools of Impressionism. Born in the town of Jackson, California on June 2, 1869, Raphael became one of the most famous students of his esteemed teacher Arthur F. Mathews at the California School of Design. Later Raphael would continue his art studies in Paris at the Ecole des Beaux-Arts, and at the Academie Julian under Jean-Paul Laurens. Early in his career he made the decision to settle in Europe in Uccle, Belgium where he and his wife established a home and raised their family. For most of his career he remained a devoted follower of pure French Impressionism. He painted the countryside near his home in Uccle, Belgium and also ventured to Holland and France to paint. Just as Raphael's international reputation grew, his family grew as well to include four daughters and one son. His family frequently appeared in his figurative works, he created wonderful closeup studies of his children and frequently captured them in leisurely picnic settings. Other paintings featured local landscapes, and sometimes his charming cottage home with its vegetable and flower gardens which were perhaps a source for his still lifes of fruits, vegetables and flowers. He lived and worked in Europe for thirty-seven years always maintaining close ties with the San Francisco art community and his loyal art dealer and collector Albert M. Bender. In 1939 with the ominous clouds of World War Two approaching, he wisely chose to return to San Francisco where he lived and maintained a studio on Sutter Street until his death on December 11th, 1950.
