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 Portinari Altarpiece | Hl.

William Gershom Collingwood
artist and historian, (1854-1932) was an author, artist, antiquary and was also Professor of Fine Arts at the Reading University. He was born in Liverpool. In 1872, he went to University College, Oxford, where he met John Ruskin. During the summer of 1873 Collingwood visited Ruskin at Brantwood, Coniston. Two years later Collingwood was working at Brantwood with Ruskin and his associates. Ruskin admired his draughtsmanship, and so Collingwood studied at the Slade School of Art between 1876 and 1878. He exhibited at the Royal Academy in 1880. For many years Collingwood dedicated himself to helping Ruskin, staying at Brantwood as Ruskin's assistant and travelling with him to Switzerland. In 1883 he married Edith Mary Isaac (1857C1928) and settled near to Ruskin in the Lake District. Collingwood edited a number of Ruskin's texts and published a biography of Ruskin in 1893. In 1896, Arthur Ransome met the Collingwoods and their children, Dora (later Mrs Ernest Altounyan), Barbara (later Mrs Oscar Gnosspelius), Ursula, and Robin (the later historian and philosopher). Ransome learned to sail in Collingwood's boat, Swallow, and became a firm friend of the family, even proposing marriage to both Dora and Barbara (on separate occasions). After a summer of teaching Collingwood's grandchildren to sail in Swallow II in 1928, Ransome wrote the first book in his Swallows and Amazons series. He used the names of some of Collingwood's grandchildren for his characters, the Swallows. By the 1890s Collingwood had become a skilled painter and also joined the Cumberland and Westmorland Antiquarian and Archaeological Society. He wrote a large number of papers for its Transactions; becoming editor in 1900. Collingwood was particularly interested in Norse lore and the Norsemen, and he wrote a novel, Thorstein of the Mere which was a major influence on Arthur Ransome. Collingwood was a member of the Viking Club and served as its president. His study of Norse and Anglican archaeology made him widely recognized as a leading authority. Following Ruskin's death Collingwood continued to help for a while with secretarial work at Brantwood, but in 1905 went to University College, Reading and served as professor of fine art from 1907 until 1911.
HIGHMORE, Joseph
English Painter, 1692-1780 English painter and writer. The son of a coal merchant and the nephew of Thomas Highmore (1660-1720), Serjeant-Painter to the King, he was articled to an attorney on 18 July 1707. Bored with his duties, he attended Kneller's Academy from 1713 and in 1715 abandoned law, setting up as a portrait painter in the City of London. From 1720 he attended the St Martin's Lane Academy, where he was able to study contemporary French styles in art and design, particularly that of Gravelot. He read widely and mastered Brook Taylor's system of perspective (1715). He also attended William Cheselden's anatomy lectures and contributed designs to that author's Anatomy of the Human Body (1722).
