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 Benois Madonna with a Flower | The Battle of Anghiari | Study of a child | Study for a kneeling Leda | The Last Supper |

Luce, Maximilien
French Pointillist Painter, 1858-1941 French painter and printmaker. He was born and brought up in the working-class surroundings of Montparnasse, and an interest in the daily routines and labours of the petit peuple of Paris informs much of his art. After an apprenticeship with the wood-engraver Henri Theophile Hildebrand (b 1824), in 1876 he entered the studio of the wood-engraver Eugene Froment where he assisted in the production of engravings for various French and foreign publications such as L'Illustration and The Graphic. He also sporadically attended classes at the Academie Suisse and in the studio of Carolus-Duran. In Froment's studio he came into contact with the artists Leo Gausson and Emile-Gustave Peduzzi
Sir Edward john poynter,bt.,P.R.A
1836-1919 English painter, draughtsman, decorative designer and museum official. He came from an artistic family: his great-grandfather was Thomas Banks the sculptor, and Ambrose Poynter, his father, was an architect and watercolour painter. Edward began studying art in 1852 under Thomas Shotter Boys, a friend of his father. In 1853-4 Poynter visited Rome, where he was greatly impressed by the large-scale academic painting of Frederic Leighton. Returning to London, he studied at Leigh's Academy and the studio of William Dobson (1817-1898). Poynter entered the Royal Academy Schools in 1855 but his admiration for French painting led him to Charles Gleyre's studio in Paris the following year. He remained there until 1859, with fellow students George Du Maurier, Thomas Armstrong and Whistler; their activities are described in Du Maurier's novel Trilby (1894). At this time Poynter received his first commissions for decorative work. He began designing stained glass and painting furniture and, after his return to England, he was employed by his friend the architect William Burges to decorate the ceiling of Waltham Abbey, Essex, in 1860.
