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 :. | Mona Lisa | Master of the Pala Sforzesca, profile of an old man | Madonna in the rock grottos | Ceiling decoration yy | Gekrose of the intestine and its Gefabsystems |

Robert Cleveley
British, 1747-1809,was an English maritime painter. His father and twin brother (John Cleveley the Elder, c.1712?C1777, and John Cleveley the Younger, 1747?C1786) were also artists, with John the Younger (and possibly Robert too, to judge from his style) gaining some training in watercolours from Paul Sandby, previously a teacher at the Royal Military Academy, Woolwich. John the Elder had tried and failed to make a living in working in a dockyard, and so did Robert, as a caulker. However, mocked by other dockyard workers for wearing gloves whilst working, John did not enjoy his time there, giving it up and in 1770 volunteering for the navy as a clerk. His first service as a clerk was briefly under Captain William Locker (who acted as patron to artists probably known to John the Elder), then soon afterwards under Captain George Vandeput on his voyage in the Asia to the West Indies and North America, during which time Vandeput became a lifelong friend. The Asia returned in 1777, and from then to the end of his life Robert followed a double career as purser on board various ships stationed in the Home Fleet (though most probably exercising his functions through a deputy for some or all of the time) and as a marine painter. This meant he could exhibit his works as "Robert Cleveley of the Royal Navy". First exhibiting at the Royal Academy in 1780, his specialism was naval battles (though he also produced pictures of royal naval occasions, such as his "View of the Fleet at Spithead Saluting George III at his Review in 1793", now at the National Maritime Museum) and many of his works were reproduced as engravings. Like his brother John, he also exploited their brother James' presence as a carpenter on Captain Cook's third voyage to gain access to art produced on the voyage and to produce art to cash in on the popular demand for South Sea images (eg a 1789 print of A view of Botany Bay). He did, however, still make occasional voyages with Vandeput, such as when he served as eassistant to the clerk of the kitchene in the royal entourage when the royal yacht Princess Augusta (under Vandeput) took Prince William Henry, later Duke of Clarence, to Hanover in July and August 1783.
