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 :. | Portrait de femme,dit a tort La belle ferronniere | Ceiling decoration yy | St Jerome sgyu | Profiles of a young and an old man | The Annunciation |

William Knight Keeling
(1807-1886) was a British (Victorian) artist, an illustrator of Walter Scott's novels and Shakespeare's plays, a founder and the third President of the Manchester Academy of Fine Arts. William Knight Keeling. Love's Messenger. 1856William Knight Keeling was born in Manchester. He was apprenticed to a wood-engraver, and in the 1830s went to London and became an assistant of William Bradley (1801-1857), a Manchester-born portrait painter who moved to London in 1822 and established himself as a portrait painter. However, Keeling returned to Manchester in 1835 and firmly established himself as a popular and respected portrait and figurative painter in oils and watercolour, and a drawing-master. From 1830s, he actively exhibited in Manchester, Liverpool and elsewhere. In 1833, his painting 'The Bird's Nest' was awarded the silver medal from the Royal Manchester Institution. In 1841, he was elected a member of the New Society of Painters in Watercolours where he exhibited about 60 works. In 1859, Keeling became a founder of the Manchester Academy of Fine Arts, and its third president from 1865 to 1877. He was a member of the Manchester Literary Club and the Brasenose Club. In the 1850s, following the notion of the day, he travelled to Spain. This journey gave him new ideas, subjects, and motifs. Delicate details and clear and bright palette inspired by hot colours of the South, are distinctive features of his paintings and watercolours. In 1873, a Manchester newspaper praised one of his watercolours as "an exquisite work, perfectly Spanish". He also was influenced by works by the great Spanish artist Bartolome Esteban Murillo (1617-1682). Murilloes street children can be easily recognised in Keelinges compassionate depictions of poor children, both British and Spanish. His eSpanish Boye exhibited in Manchester in 1876, was described as "a very good example of the careful and accurate method pursued by the artist. He is thoroughly conscientious in all his professional work." In 1851, in London, Keeling married Mary Ann Charker (b.1822). They had four children: Edith (b.1852), Dalton Harper (b.1853), Sidney Charles (b.1859), and Gertrude Ann (b.1862). Keeling died on 21.02.1886 in his house at Barton-upon-Irwell, Manchester. Keeling did not strive for fame and glory, and remained in the background of the artistic life of his time, although many connoisseurs appreciated his works. Several his works have been preserved at Victoria & Albert Museum, London. In the 1870s, Wolverhampton industrialist and collector Sidney Cartwright purchased from a Manchester exhibition a large number of Keelinges works. In 1887, they were given to Wolverhampton Art Gallery which possesses today possibly the largest collection of Keelinges paitings and watercolours in the United Kingdom.
