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 :. | A rock gorge | Head and shoulders Christs | The Refectory with the Last Supper after restoration g | Benois Madonna | The Annunciation |

John Christian Schetky
(1778-1874) Scottish painter. Schetky came from a cultured family: his father, Johann (1737-1824), was a German composer, and his mother, Maria, was the trumpeter Joseph Reinagle's sister. He took drawing lessons from Alexander Nasmyth and received a good education in Edinburgh before embarking on a Continental tour in 1801. After a spell as a drawing-master at the Royal Military College, Great Marlow, he was appointed Professor of Drawing at the Royal Naval College, Portsmouth, in 1811, a post he held for 25 years. He exhibited regularly at the Royal Academy between 1805 and 1872, his subjects ranging from ship portraits and royal embarkations to reconstructions of earlier sea battles of the time of Nelson. In 1820 he was made Marine Painter in Ordinary to George IV and was granted the same title by Queen Victoria in 1844.
SALINI, Tommaso
Italian painter, Roman school (b. 1575, Roma, d. 1625, Roma).Italian painter. He has long been famed as a witness in the lawsuit of 1603 brought by his friend and biographer, Giovanni Baglione, against Caravaggio. His activity as a painter of religious works, still-lifes and genre paintings has been reconstructed in the decades following 1950, although his chronology remains uncertain. He entered the Accademia di S Luca in 1605 but was afterwards expelled on account of his 'difetto', to be readmitted in 1618. He was decorated with the Order of the Golden Spur and became a member of the Congregazione di Virtuosi al Pantheon.
