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 :. | Study of an apostle | Annunciation sgt66 | Madonna with the Yarnwinder | The last dinner | The Virgin and Child with St Anne |

John Rogers Herbert
English historical painter and portraitist . British, 1810-1890. was an English painter who is most notable as a precursor of Pre-Raphaelitism. Herbert was born in Maldon, Essex. In 1825, he moved to London to study at the Royal Academy. His early works were influenced by the troubadour style of Richard Parkes Bonington. Subjects showed the influence of Byron and exotic episodes of Venetian history. Haydee (1834) depicted the heroine of Byron's poem Don Juan. Herbert's first major success was The Appointed Hour (1835), depicting a melodramatic scene in which a Venetian man lies murdered at the place appointed for a tryst with his lover. The work became a popular engraving. Herbert followed it with other dramatic subjects such as A Prisoner of Condottieri Freed (1836) and Desdemona asks for Cassio (1838). After he was chosen to paint a portrait of Princess Victoria, before she became queen, he became a favourite portrait painter of the aristocracy. Around this time, he came under the influence of the architect William Payne, a convert to Catholicism. In 1840, Herbert also converted to the Catholic Church. He then painted mainly religious subjects in a style influenced by the artists of the Nazarene movement. Herbert was elected to membership of the Royal Academy in 1846. Herbert's paintings The First Introduction of Christianity into Great Britain (1842) and Our Saviour Subject to his Parents in Nazareth (1847) were the inspiration for the two most important early works of William Holman Hunt and John Everett Millais, founders of Pre-Raphaelitism. The two paintings, Hunt's A Converted British Family Sheltering a Christian Missionary and Millais' Christ in the House of His Parents were exhibited at the RA in 1850 to great controversy.
