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 :. | Profile of an old man | Virgin and Child with St Anne and St John the Baptist (mk08) | Adoration of the Magi (mk08) | Last Supper | The Virgin and St Anne |

Paxton, William McGregor
American Painter, 1869-1941 was an American Impressionist painter. Born in Baltimore, the Paxton family came to Newton Corner in the mid-1870s, where William's father James established himself as a caterer. At 18, William won a scholarship to attend the Cowles Art School, where he began his art studies with Dennis Miller Bunker. Later he studied with Jean-L??on G??rôme in Paris and, on his return to Boston, with Joseph DeCamp at Cowles. There he met his future wife Elizabeth Okie, who also was studying with DeCamp. After their marriage, William and Elizabeth lived with his parents at 43 Elmwood Street, and later bought a house at 19 Montvale Road in Newton Centre. Paxton, who is best known as a portrait painter, taught at the Museum School from 1906 to 1913. Along with other well known artists of the era, including Edmund Charles Tarbell and Frank Benson, he is identified with the Boston School. Like many of his Boston colleagues, Paxton found inspiration in the work of the seventeenth-century Dutch painter Johannes Vermeer. Paxton was fascinated not only with Vermeer's imagery, but also with the system of optics he employed. He studied Vermeer's works closely, and discovered that only one area in his compositions was entirely in focus, while the rest were somewhat blurred. Paxton ascribed this peculiarity to "binocular vision," crediting Vermeer with recording the slightly different point of view of each individual eye that combine in human sight. He began to employ this system in his own work, including The New Necklace, where only the gold beads are sharply defined while the rest of the objects in the composition have softer, blurrier edges.
