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 :. | Lorenzo de Medici between Antonio Pucci and Francesco Sassetti, with Giulio de Medici, fresco by Ghirlandaio | Madonna with the Yarnwinder (detail) dft | Gekrose of the intestine and its Gefabsystems | Annunciation sgt66 | Profile of an old man |

Grace Carpenter Hudson
1865-1937 Grace Carpenter Hudson Galleries Grace Carpenter Hudson (1865 - 1937) was an American painter. She was nationally known during her lifetime for a numbered series of more than 684 portraits of the local Pomo Indians. She painted the first, "National Thorn", after her marriage in 1891, and the last in 1935. Grace Carpenter was born in Potter Valley, California. Her mother was one of the first white school teachers educating Pomo children and was a commercial portrait photographer in Ukiah, California; her father was a skilled panoramic and landscape photographer who chronicled early Mendocino County frontier enterprises such as logging, shipping and railroading.[1] At fourteen years of age, Grace was sent to attend the recently-established San Francisco School of Design, an art school which emphasized painting from nature rather than from memory or by copying existing works. At sixteen, she executed an award-winning, full length, life sized self-portrait in crayon. While in San Francisco, she met and eloped with a man fifteen years her senior named William Davis, upsetting her parents and ending her formal studies. The marriage lasted only a year. From 1885 to 1890, Grace Carpenter Davis lived with her parents in Ukiah painting, teaching and rendering illustrations for magazines such as Cosmopolitan and Overland Monthly. Her work at that time had no particular focus and included genre, landscapes, portraits and still lifes in all media. Later in her career she would continue to accept occasional magazine illustration assignments including ones for Sunset.
