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 | The Verkundigung | Hl.

John William Inchbold
1830-1888 English painter. He spent his early years in Leeds, where his father was a newspaper proprietor, but came to London around 1846 to study lithography in the firm of Day & Haghe. His obituary in The Athenaeum records that he went on to study at the Royal Academy Schools, but his name does not appear in the registers. He exhibited watercolours at the Society of British Artists in 1849 and 1850 and at the Royal Academy in 1851. At this period his work has a fluidity and a freedom of handling that is closer to Richard Parkes Bonington than to the prevailing style of Victorian watercolours. Around 1852 he came under the influence of the Pre-Raphaelite movement and radically altered his style. His oil painting of the Chapel, Bolton (exh. RA 1853; Northampton, Cent. Mus. & A.G.) is a meticulously rendered view of the abbey ruins in the Pre-Raphaelite manner. This was followed the next year by At Bolton (Leeds, C.A.G.), another view of Bolton Abbey, this time with a deer prominent in the foreground. Both paintings illustrate lines from William Wordsworth's poem 'The White Doe of Ryleston'. Wordsworth was also the inspiration for the small painting Study in March
Joseph Severn
(7 December 1793 - 3 August 1879) was an English portrait and subject painter and a personal friend of the famous English poet John Keats. He exhibited portraits, Italian genre, literary and biblical subjects, and a selection of his paintings can today be found in some of the most important museums in London, including the National Portrait Gallery, the Victoria and Albert Museum and the Tate Britain. The eldest son of a music teacher, Severn was born at Hoxton, near London, and apprenticed at the age of 14 to William Bond, an engraver. Severn was one of seven children; two of his brothers, Thomas (1801-1881) and Charles (1806-1894), became professional musicians, and Severn himself was an adroit pianist. During his early years he practised portraiture as a miniaturist.
