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 :. | anna sjalv tredje | Lady with Ermine | Head and shoulders Christs | Mona Lisa | Mona Lisa (detail) r y |

Caillebotte, Gustave
French Impressionist Painter, 1848-1894 .French painter and collector. Caillebotte's parents, of Norman descent, were wealthy members of the Parisian upper middle class, and his paintings often evoke his family background. After studying classics at the Lyc?e Louis Le Grand, he obtained a law degree in 1870, and during the Franco-Prussian War he was drafted into the Seine Garde Mobile (1870-71). He joined L?on Bonnat's studio in 1872 and passed the entrance examination for the Ecole des Beaux-Arts on 18 March 1873. The records of the Ecole make no mention of his work there, and his attendance seems to have been short-lived. He was very soon attracted by the innovative experiments, against academic teaching, of the young rebels who were to become known as the Impressionists. In 1874 Edgar Degas, whom Caillebotte had met at the house of their mutual friend Giuseppe de Nittis, asked him to take part in the First Impressionist Exhibition at the Nadar Gallery in the Boulevard des Capucines in Paris. However, it was only at the time of their second exhibition in April 1876 that, at Auguste Renoir's invitation, Caillebotte joined the Impressionist group. From then on he was one of the most regular participants in their exhibitions (1877, 1879, 1880, 1882). He organized the show of 1877 and made great efforts to restore the cohesion of the group by persuading Claude Monet to exhibit in 1879.
J B Armand Guillaumin
1841-1927 Born Jean-Baptiste Armand Guillaumin in Paris, France, he worked at his uncle's lingerie shop while attending evening drawing lessons. He also worked for a French government railway before studying at the Academie Suisse in 1861. There, he met Paul C??zanne and Camille Pissarro with whom maintained lifelong friendships. While he never achieved the stature of these two, his influence on their work was significant. C??zanne attempted his first etching based on Guillaumin paintings of barges on the River Seine. Guillaumin exhibited at the Salon des Refus??s in 1863 and later became a friend of Vincent van Gogh whose brother, Theo sold some of his works. Noted for his intense colors, major museums around the world display Guillaumin's art. He is best remembered for his landscapes of Paris, the Creuse departement, and the area around Les Adrets-de-l'Esterel near the Mediterraneran coast in the Provence-Alpes-Cote d'Azur region of France. Armand Guillaumin died in 1927 in Orly, Val-de-Marne just south of Paris.
