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 :. | Six studies fur naked or clothed men | Aurelio Luini attributed, profile of an old man | Portrait de Mona Lisa dit La joconde | Leonardo there Vinci and Andrea del Verrocchio, madonna with the child and angels | Funf studies of grotesque faces |

John Peter Russell
(16 June 1858 -22 April 1930) was an Australian impressionist painter. John Peter Russell was born at the Sydney suburb of Darlinghurst, the eldest of four children of John Russell, a Scottish engineer, his wife Charlotte Elizabeth, nee Nicholl, from London. J. P. Russell was a nephew of Sir Peter Nicol Russell. After his father's death J. P. Russell enrolled at the Slade School of Fine Art, University College, London, on 5 January 1881 and studied under Alphonse Legros for three years.Russell then went to Paris to study painting under Fernand Cormon. (His fellow students there included Henri de Toulouse-Lautrec and Émile Bernard.) Russell was a man of means and having married a beautiful Italian, Mariana Antoinetta Matiocco, he settled at Belle Île off the coast of Brittany, where he established an artists' colony. He would have 11 children with Matiocco, of whom six survived. John Peter Russell: Vincent van Gogh, 1886, Van Gogh Museum, AmsterdamRussell had met Vincent van Gogh in Paris and formed a friendship with him. Van Gogh spoke highly of Russell's work, and after his first summer in Arles in 1888 he sent twelve drawings of his paintings to Russell, to inform him about the progress of his work. Claude Monet often worked with Russell at Belle Île and influenced his style, though it has been said that Monet preferred some of Russell's Belle Île seascapes to his own.

American Painter, 1808-1886 American painter. Beginning as an itinerant portrait painter in rural Pennsylvania, he produced works including flattering, colourful portraits of his sisters in the style of Thomas Sully, often incorporating small still-life details. He abandoned portraiture after 1850 to concentrate exclusively on still-life subjects in the tradition of the PEALE family.
