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 and Child with a Pomegranate et | Madonna Litta (detail sdg | The Last Supper | Madonna with a Flower (Madonna Benois) g | Leda and the Swan |

James Sharples
(1751 or 1752 in Lancashire - 26 February 1811 in New York ) was an English portrait painter and pastelist, who moved to the United States in 1794. He first exhibited at the Royal Academy in 1779. James was first intended for the Catholic priesthood, but became an artist instead.Sharples headed a family of successful portrait artists, including his third wife Ellen Sharples. He had four children, George by his first wife, Felix Thomas Sharples from his second marriage (c. 1786- after 1823), and James Sharples Jr.(c. 1788-1839) and daughter Rolinda Sharples (1793-1838) with this third wife, Ellen. Felix, James Jr. and Rolinda joined the family enterprise at ages 17, 15, and 13 respectively. Before marrying Ellen Wallace, James had been active in Bristol, Liverpool and Bath, where he taught drawing. Ellen was a lady of French extraction who had relations in America. The family left for the United States in 1796, but, according to Ellen's diaries, their ship fell into the hands of the French, and for seven months the family spent time in Brest, near Cherbourg. Landing in New York, James quickly became popular for his small portraits in pastel and his miniatures. From 1796 to 1801 he worked mainly in Philadelphia and New York, securing portrait commissions. The family traveled throughout New England region as itinerant portrait painters, looking for work and making inexpensive copies from the originals portraits they had made of popular and well-known figures, such as George Washington and James Madison.
Canaletto
Italian Rococo Era Painter, 1697-1768 Italian painter, etcher and draughtsman. He was the most distinguished Italian view painter of the 18th century. Apart from ten years spent in England he lived in Venice, and his fame rests above all on his views (vedute) of that city; some of these are purely topographical, others include festivals or ceremonial events. He also painted imaginary views (capriccios), although the demarcation between the real and the invented is never quite clearcut: his imaginary views often include realistically depicted elements, though in unexpected surroundings, and in a sense even his Venetian vedute are imaginary. He never merely re-created reality. He was highly successful with the English, helped in this by the British connoisseur JOSEPH SMITH, whose own large collection of Canaletto works was sold to King George III in 1762. The British Royal Collection has the largest group of his paintings and drawings.
