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 :. | Madonna and Child with St Anne and the Young St John | Six studies fur naked or clothed men | Study of the proportion of horses | Muscle structure of the thigh | Leda (detail) ghk |

Walter Withers
English-born Australian Painter, 1854-1914 was an Australian landscape artist and a member of the Heidelberg School of Australian impressionists. Withers was born at Handsworth, Staffordshire, the son of Edwin Withers. He showed an early desire to paint, but objection was made to this by his father. It is not known what occupation he followed in England, but in 1882 he arrived in Australia with the intention of going on the land. After working for about 18 months on a farm, Withers removed to Melbourne and obtained a position as draughtsman in a firm of printers. He then took up his painting again, and began to exhibit with the Victorian Academy of Arts afterwards merged in the Victorian Artists' Society. In 1887 Withers went to Europe. There he was married to Miss F. Flinn and studied for some months at the Academie Julian, Paris. He returned to Australia with his wife in June 1888 having been commissioned to do black and white work for Messrs Fergusson and Mitchell of Melbourne. His most important work in this way will be found in the illustrations to Edmund Finn's, The Chronicles of Early Melbourne. Withers settled down at first at Kew, a suburb of Melbourne, and then near Heidelberg on the other side of the river Yarra. He became friendly with Arthur Streeton, Charles Conder, Tom Roberts, Frederick McCubbin and other leading artists of the period. He began to sell a few pictures, but the collapse of the land boom put an end to his illustrative work. He obtained some work as a drawing and painting master in schools, and in 1891 opened a studio in Collins-street west, where he held his first private exhibition.
