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 :. | Annunciation (detail) st | The Verkundigung | Annunciation sgt66 | Maria with Child and St. Anna | Studies of children |

Frida Kahlo
1907-54 Mexican painter, b. Coyoacen. As a result of an accident at age 15, Kahlo turned her attention from a medical career to painting. Drawing on her personal experiences, her works are often shocking in their stark portrayal of pain and the harsh lives of women. Fifty-five of her 143 paintings are self-portraits incorporating a personal symbolism complete with graphic anatomical references. She was also influenced by indigenous Mexican culture, aspects of which she portrayed in bright colors, with a mixture of realism and symbolism. Her paintings attracted the attention of the artist Diego Rivera, whom she later married. Although Kahlo's work is sometimes classified as surrealist and she did exhibit several times with European surrealists, she herself disputed the label. Her preoccupation with female themes and the figurative candor with which she expressed them made her something of a feminist cult figure in the last decades of the 20th cent.
Cornelius Krieghoff
Dutch-born Canadian Painter, 1815-1872 Canadian painter of Dutch birth. He learnt the rudiments of music and painting from his father and about 1830 attended the Akademie der Bildenden Kenste in D?sseldorf. He moved to America c. 1835 and enlisted in the US army. In New York he met Louise Gauthier, a French-Canadian, and settled in Montreal with her in 1840, working as a painter and a musician. In 1842-3 he had a studio in Rochester, NY; in the following year he studied in Paris, making copies in the Louvre. Returning to Canada in 1845, he painted portraits in Toronto, and from 1845 to 1853 he lived in Longueuil and then in Montreal, where he produced genre paintings, landscapes and portraits. He exhibited in Montreal and Toronto, and a series of lithographs were published after his drawings. However, he found it difficult to sell his work in Montreal and had to resort more or less completely to sign-painting for a living. About 1853, at the instigation of the auctioneer John Budden, Krieghoff settled in Quebec City. He lived there for 11 years, making several trips to Europe. During this period of intensive production, he achieved popularity and prosperity and painted his best-known pictures, which were scenes depicting the local townspeople and the North American Indians, and views of Quebec City and the surrounding region. About 1858 he made panoramic paintings of Canada for the Provincial Parliament buildings in Quebec. From 1864 to 1867 he lived in Paris and Munich,
