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 :. | The Last Supper | Mona Lisa (La Gioconda) sdg | Mona Lisa (detail) r y | Profile one with book leaves gekroten of old man | Details of Mona Lisa |

Richard Dadd
1817-1886 was an English painter of the Victorian era, noted for his depictions of fairies and other supernatural subjects, Orientalist scenes, and enigmatic genre scenes, rendered with obsessively minuscule detail. Most of the works for which he is best known were created while he was incarcerated in a psychiatric hospital. Dadd was born at Chatham, Medway in Kent, England, the son of a chemist. His aptitude for drawing was evident at an early age, leading to his admission to the Royal Academy of Arts at the age of 20. With William Powell Frith, Augustus Egg, Henry O'Neil and others, he founded The Clique, of which he was generally considered the leading talent. In July 1842, Sir Thomas Phillips, the former mayor of Newport, chose Dadd to accompany him as his draftsman on an expedition through Europe to Greece, Turkey, Palestine and finally Egypt. In November of that year they spent a gruelling two weeks in Palestine, passing from Jerusalem to Jordan and returning across the Engaddi wilderness. Toward the end of December, while travelling up the Nile by boat, Dadd underwent a dramatic personality change, becoming delusional and increasingly violent, and believing himself to be under the influence of the Egyptian god Osiris. His condition was initially thought to be sunstroke. On his return in the spring of 1843, he was diagnosed to be of unsound mind and was taken by his family to recuperate in the countryside village of Cobham, Kent. In August of that year, having become convinced that his father was the Devil in disguise, Dadd killed him with a knife and fled for France. En route to Paris Dadd attempted to kill another tourist with a razor, but was overpowered and was arrested by the police. Dadd confessed to the killing of his father and was returned to England, where he was committed to the criminal department of Bethlem psychiatric hospital (also known as Bedlam). Here and subsequently at the newly created Broadmoor, Dadd was cared for (and encouraged to continue painting) by the likes of Drs William Wood and Sir W. Charles Hood, in an enlightened manner. Which condition he suffered from is unclear, but it is usually understood to be a form of paranoid schizophrenia.He appears to have been genetically predisposed to mental illness; two of his siblings were similarly afflicted, while a third had "a private attendant" for unknown reasons.In the hospital he was allowed to continue to paint and it was here that many of his masterpieces were created, including his most celebrated painting, The Fairy Feller's Master-Stroke, which he worked on between 1855 and 1864. Also dating from the 1850s are the thirty-three watercolour drawings titled Sketches to Illustrate the Passions, which include Grief or Sorrow, Love, and Jealousy, as well as Agony-Raving Madness and Murder. Like most of his works these are executed on a small scale and feature protagonists whose eyes are fixed in a peculiar, unfocused stare.
