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 of the Yarnwinder | Portrait of Ginevra de Benci | Annunciation (detail) fg47 | The Annunciation | Study of the proportion of horses |

Hugh Ramsay
Australian portrait painter , 1877 - 1906 was an Australian artist. Ramsay was born in Glasgow, Scotland, son of John Ramsay. He moved with his family to Melbourne in 1878. He was educated at Essendon Grammar School, and joined classes at the National Gallery of Victoria at age 16 under Lindsay Bernard Hall and became one of the most brilliant students ever trained there. He won several first prizes, and at the competition for the travelling scholarship held in 1899 was narrowly beaten by Max Meldrum, another student of unusual ability. Ramsay went to Europe in September 1900 and was fortunate in finding a kindred spirit, George Washington Lambert, on the same vessel. Arriving at Paris he entered Acad??mie Colarossi and was soon recognized as a student of great potential. He sent five pictures to the 1902 exhibition of La Soci??t?? Nationale des Beaux Arts and four of these were accepted and hung together. No greater compliment could have been paid to a young student. Another Australian student whose studio was in the same building, Ambrose McCarthy Patterson (nephew of Nellie Melba, then at the height of her fame). Ramsay was introduced to Melba, who gave him a commission for a portrait and would no doubt have been able to help him in his career. Unfortunately Ramsay became ill in Paris, and it became necessary for him to return to the warmer climate of Australia and the opportunity to paint Melba was missed. Before leaving Europe he had exhibited four pictures at the British Colonial Art Exhibition held in London at the Royal Institute galleries. Returning to Australia, in spite of failing health, Ramsay succeeded in doing some remarkable work including "The Sisters" now in the Sydney gallery, the "Lady with a Fan" (possibly his most famous painting), the portrait of David Scott Mitchell, and his own portrait now in the Melbourne gallery. He gradually became weaker and died on 5 March 1906.
