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 :. | Hi Hieronymus | Last Supper | Mona Lisa | Annunciation (detail) dfe | Madonna of the Yarnwinder |

Arthur streeton
1867 - 1943 Australian painter. He moved to Melbourne with his family when he was seven. In 1882 he enrolled as a student of drawing at the evening classes of the National Gallery School of Design and briefly in the School of Painting, but he had no sustained formal instruction in painting. At the same time he began making watercolour sketches of Melbourne, and by 1886 his skill led to an apprenticeship as a lithographer to George Troedel and Co. of Collins Street. The most important early influence on Streeton was Tom Roberts, who had returned to Melbourne from Europe in 1885. With Frederick McCubbin, Streeton and Roberts painted en plein air at a temporary camp at Box Hill, forming what became known as the HEIDELBERG SCHOOL. A little later Streeton established the first permanent artists' camp at Eaglemont, north-west of Melbourne, overlooking the Yarra Valley, where he painted some of his most memorable works.

Richard Westall
English Painter, 1765-1836 was an English painter. Westall was the more successful of two half-brothers (both sons of a Benjamin Westall, from Norwich), who each became painters. His younger half-brother was William Westall (1781C1850), a much-travelled landscape painter. Born on 2 January 1765 in Reepham near Norwich (where he was baptised at All Saints on 13 January in the same year) Richard Westall moved to London after the death of his mother and the bankruptcy of his father in 1772. He was apprenticed to a heraldic silver engraver in 1779 before studying at the Royal Academy School of Art from 10 December 1785. He exhibited at the Academy regularly between 1784 and 1836, became an Associate in November 1792 and was elected an Academician on 10 February 1794. From 1790 to 1795 he shared a house with Thomas Lawrence (later Sir), the future Royal Academy president, at 57 Greek Street, on the corner of Soho Square, each of the artists placing their name on one of the entrances. His works C many in water-colour - caused great interest in the late years of the 18th century when he was considered by his chief patron Richard Payne Knight as an outstanding artist of the picturesque. He painted works in a neo-classical style for John Boydell's Shakespeare Gallery and for Henry Fuseli's Milton Gallery. His painting of John Milton and his daughters hangs in Sir John Soane's Museum in London. A number of scenes in which Westall depicts events in the life of Horatio Nelson are at the Maritime Museum. Westall was a prolific illustrator of books of poets and writers including Sir Walter Scott and Oliver Goldsmith, Byron - who greatly admired his work, stating that "the brush has beat the poetry". He also illustrated editions of the Bible,
