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 :. | Ceiling decoration yy | Profiles of a young and an old man | The Virgin and the Nino with Holy Ana | Mona Lisa | Gekrose of the intestine and its Gefabsystems |

william henry hunt,o.w.s
1790-1864 was an English watercolour painter. He was born near Long Acre, London, and was apprenticed in about 1805 to John Varley, the landscape-painter, with whom he remained five or six years. He exhibited three oil pictures at the Royal Academy in 1807. He became connected with the Society of Painters in Water Colours at its beginning, and was elected an associate in 1824 and a full member in 1827. Until the year of his death, he was one of the most prolific contributors to the Society's exhibitions. Many years of Hunt's uneventful but industrious life were spent at Hastings. He died of apoplexy. Hunt was one of the creators of the English school of water-color painting. His subjects, especially those of his later life, are extremely simple; but, by the delicacy, humor and fine power of their treatment, they rank second to works of the highest art only. Considered technically, his works exhibit all the resources of the water-color painter's craft, from the purest transparent tinting to the boldest use of gouache, rough paper and scraping for texture. His sense of color is perhaps as true as that of any English artist. He was, says John Ruskin, all in all, the finest ever painter of still life. Several characteristic examples of Hunt's work, as the "Boy and Goat," "Brown Study and Plums," "Primroses and Birds' Nests" are in the Victoria and Albert Museum.
