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 :. | Virgin of th Rock (mk08) | Annunciation sgt66 | Madonna with the carnation | Study Fur the Trivulzio-monument | Study fur the Trivulzio-monument |

He went to Canton in September 1838 and stayed in the region for 10 months. While in Canton, he met the English artist George Chinnery, and they went on sketching trips together. In July 1839 he visited Manila, Singapore and Calcutta. In 1840 he traveled widely in India, returning to Paris in the summer of that year. Borgetes sketches and watercolors from China were the basis for his most famous publication "Sketches of China and the Chinese", published in 1842. His book "La Chine ouverte" was illustrated with fine woodcut engravings. A major Salon of his original works, including watercolors and boldly executed oil paintings was held in Paris in 1843. Borget died in 1877.
Gustavus Hesselius
(1682 - May 25, 1755) was a Swedish born painter who emigrated to the New World in 1711. He was the father of painter John Hesselius and cousin of the religious leader Emanuel Swedenborg. Hesselius left his home country of Sweden for Wilmington, Delaware in 1711. There he lived until 1717 when he moved to Philadelphia, Pennsylvania, where he lived until 1721. In 1721, he moved to Prince George's County, Maryland and became a portrait painter, though he had been trained in Sweden. That same year, he received the first recorded public art commission in the American colonies, he painted The Last Supper. He also painted a Crucifixion. Some time around 1735, Hesselius returned to Philadelphia where spent the rest of his life and traveling. He was listed as a member of the Gloria Dei (Old Swedes') Church in Philadelphia. He also worked as an organ builder, having built an organ for the Moravian Church in Bethlehem, Pennsylvania in 1746. From about this time on, he focused on building organs, referring painting commissions to his son John. J. Hall Pleasants has said that Hesselius became "America's earliest portrait painter of note." In 1994 he was named to the Prince George's County Hall of Fame.
