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 | Head and shoulders Christs | Mona Lisa | Madonna in the rock grottos | virgin and child with st.anne |

John Frederick Herring
British 1795-1865 was a painter, sign maker and coachman in Victorian England.John F. Herring, Sr. is the painter of the 1848 "Pharoah's Chariot Horses" (archaic spelling "Pharoah"). He amended his signature "SR" (senior) in 1836, with the growing fame of his teenage son John Frederick Herring, Jr.Herring, born in London in 1795, was the son of a London merchant of Dutch parentage, who had been born overseas in America. The first eighteen years of Herring's life were spent in London, England, where his greatest interests were drawing and horses.In the year 1814, at the age of 18, he moved to Doncaster in the north of England, arriving in time to witness the Duke of Hamilton's "William" win the St. Leger Stakes horserace. By 1815, Herring had married Ann Harris; his sons John Frederick Herring, Jr., Charles Herring, and Benjamin Herring were all to become artists, while his two daughters, Ann and Emma, both married painters. In Doncaster, England, Herring was employed as a painter of inn signs and coach insignia on the sides of coaches,and his later contact with a firm owned by a Mr. Wood led to Herring's subsequent employment as a night coach driver. Herring spent his spare time painting portraits of horses for inn parlors, and he became known as the "artist coachman" (at the time).Herring's talent was recognized by wealthy customers, and he began painting hunters and racehorses for the gentry. In 1830, John Frederick Herring, Senior left Doncaster for Newmarket, England, where he spent three years before moving to London, England. During this time, Herring might have received tuition from Abraham Cooper. In London, Herring experienced financial difficulties and was given financial assistance by W. T. Copeland, who commissioned many paintings, including some designs used for the Copeland Spode bone china. In 1840-1841, Herring visited Paris, painting several pictures, on the invitation of the Duc d'Orleans.
