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 Annunciation | The Virgin of the rocks | Kvinnoportratt | The Virgin and St Anne | Leonardo there Vinci and Andrea del Verrocchio, madonna with the child and angels |

Homer Dodge Martin
American Barbizon School Tonalist Painter, 1836-1897, He was an American artist, particularly known for his landscapes. Martin was born at Albany, New York. A pupil for a short time of William Hart, his earlier work was closely aligned with the Hudson River School. He was elected as associate of the National Academy of Design, New York, in 1868, and a full academician in 1874. During a trip to Europe in 1876 he was captivated by the Barbizon school, and thereafter his painting style gradually became darker, moodier, and more loosely-brushed. From 1882 to 1886 he lived in France, spending much of the time in Normandy.

David Teniers the Younger
(December 15, 1610 C April 25, 1690), a Flemish artist born in Antwerp, was the more celebrated son of David Teniers the Elder, almost ranking in celebrity with Rubens and Van Dyck. His son David Teniers III and his grandson David Teniers IV were also painters. His wife Anna nee, Anna Breughel was the daughter of Jan Brueghel the Elder and the granddaughter of Pieter Bruegel the Elder. Through his father, he was indirectly influenced by Elsheimer and by Rubens. The influence of Adriaen Brouwer can be traced to the outset of his career. There is no evidence, however, that either Rubens or Brouwer interfered in any way with Teniers's education, and Smith (Catalogue Raisonne) may be correct in supposing that the admiration which Brouwer's pictures at one time excited alone suggested to the younger artist his imitation of them. The only trace of personal relations having existed between Teniers and Rubens is the fact that the ward of the latter, Anne Breughel, the daughter of Jan (Velvet) Breughel, married Teniers in 1637.
