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 :. | Leda h | The Adoration of the Magi | Madonna Litta (detail sdg | Mona Lisa (detail) dyk | The master of the Pala Sforzesca attributed |

Charles Hazelwood Shannon
English painter, printmaker and collector , 1863-1937 English artist, was born at Sleaford in Lincolnshire, the son of the Rev. Frederic Shannon. He attended the City and Guilds of London Art School (then known as South London School of Technical Art, formerly Lambeth School of Art), and was subsequently considerably influenced by his lifetime partner Charles Ricketts[2] and by the example of the great Venetians. In his early work he was addicted to a heavy low tone, which he abandoned subsequently for dearer and more transparent colour. He achieved great success with his portraits and his Giorgionesque figure compositions, which are marked by a classic sense of style, and with his etchings and lithographic designs. The Dublin Municipal Gallery owns his circular composition "The Bunch of Grapes" and "The Lady with the Green Fan" (portrait of Mrs Hacon). His "Study in Grey" is at the Munich Gallery, a "Portrait of Mr Staats Forbes" at Bremen, and a "Souvenir of Van Dyck" at Melbourne. One of his most remarkable pictures is "The Toilet of Venus" in the collection of Lord Northcliffe. Several of his portrait works are on display in the National Portrait Gallery in London. Complete sets of his lithographs and etchings have been acquired by the British Museum and the Berlin and Dresden print rooms. He was awarded a first-class gold medal at Munich in 1895 and a first-class silver medal in Paris in 1900.
