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 Virgin and St Anne | The Annunciation | The Annunciation | Reverse side of the portrait of Ginevra de' Benci | Profile of a man |

Charles Rennie Macintosh
Scottish Art Nouveau Designer , (1868-1928). Scottish architect, designer and painter. In the pantheon of heroes of the Modern Movement, he has been elevated to a cult figure, such that the importance of his late 19th-century background and training in Glasgow are often overlooked. He studied during a period of great artistic activity in the city that produced the distinctive GLASGOW STYLE. As a follower of A. W. N. Pugin and John Ruskin, he believed in the superiority of Gothic over Classical architecture and by implication that moral integrity in architecture could be achieved only through revealed construction. Although Mackintosh's buildings refrain from overt classicism, they reflect its inherent discipline. His profound originality was evident by 1895, when he began the designs for the Glasgow School of Art. His decorative schemes, particularly the furniture, also formed an essential element in his buildings. During Mackintosh's lifetime his influence was chiefly felt in Austria, in the work of such painters as Gustav Klimt and such architects as Josef Hoffmann and Joseph Maria Olbrich. The revival of interest in his work was initiated by the publication of monographs by Pevsner (1950) and Howarth (1952). The Charles Rennie Mackintosh Society was formed in Glasgow in 1973; it publishes a biannual newsletter, has a reference library and organizes exhibitions.
