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 :. | The Baptism of Christ (detail) sg | Mona Lisa | Plan fur a canal to the evasion of the Arno | Mona Lisa | The Baptism of Christ |

William Aikman
William Aikman (24 October 1682 - 7 June 1731) was a Scottish portrait-painter. Aikman was the son of William Aikman, of Cairney. His father intended that he should follow the law, and gave him an education suitable to these views; but the strong predilection of the son to the fine arts induced him to attach himself to painting alone. Poetry, painting, and music have, with justice, been called sister arts. Mr. Aikman was fond of poetry; and was particularly delighted with those unforced strains which, proceeding from the heart, are calculated to touch the congenial feelings of sympathetic minds. It was this propensity that attached him so warmly to Allan Ramsay, the Doric bard of Scotland. Though younger than Ramsay, Mr. Aikman, while at college, formed an intimate acquaintance with him, which constituted a principal part of his happiness at that time, and of which he always bore the tenderest recollection. It was the same delicate bias of mind which at a future period of his life attached him so warmly to Thomson, who then unknown, and unprotected, stood in need of, and obtained the warmest patronage of Aikman; who perhaps considered it as one of the most fortunate occurrences in his life that he had it in his power to introduce this young poet of nature to Sir Robert Walpole, who wished to be reckoned the patron of genius, and to Arbuthnot, Swift, Pope, Gay, and the other beaux esprits of that brilliant period. Thomson could never forget this kindness; and when he had the misfortune, too soon, to lose this warm friend and kind protector, he bewailed the loss in strains distinguished by justness of thought, and genuine pathos of expression.
