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 :. | Portrait of Cecilia Gallerani | Grotesque profile of a man | The Annunciation | Knieened figure in Draperie | Virgin of the Rocks |

Ivan Nikitin
Russian Painter, ca.1680-1742,Russian painter. The son of a Moscow priest who was close to the imperial court, Nikitin probably studied at the workshop of the Armoury Palace in Moscow and subsequently worked chiefly in St Petersburg. His early portraits were of Peter the Great and members of Peter family, for example the portraits of Peter daughters Elizabeth (St Petersburg, Rus. Mus.) and Anne (Moscow, Tret yakov Gal.) and of his sister Natal ya Alekseyevna (St Petersburg, Rus. Mus.). One of the few signed and dated works is a portrait of Praskov ya Ioannovna, Daughter of Tsar Ivan V (1714; St Petersburg, Rus. Mus.). Nikitin style was formed at the time of Peter the Great reforms of the administrative and education system in Russia, and he ranks as a pioneer of a new style in Russian painting. In his early works, up to 1716, he adapted the medieval Russian style of portraiture to the forms of contemporary European examples.
Charles Laval
(1862-1894) was a French painter born March 17, 1862 in Paris and who died April 27, 1894. He is associated with the Synthetic movement and Pont-Aven School, and he was a contemporary and friend of Paul Gauguin and Vincent van Gogh. Gauguin created a portrait of him in 1886 looking at one of Gauguin's Ceramic sculptures, entitled "Still Life with Profile of Laval". Paul Gauguin and Laval both came to Pension Gloanec in Pont-Aven in 1886 and became friends. In search of an exoticism that could provide the key to art, Gauguin and Laval went to Panama in 1887. To gain some subsidies, Laval performs academic portraits (all lost), using his experience received from Leon Bonnat. A series of mishaps caused Laval and Gauguin to leave the Central America for the island of Martinique.
Robert Walter Weir
Jun 18.1803-May 1.1889, Painter and teacher. By his own account he was self-taught, with the exception of a few lessons from an unknown heraldic painter named Robert Cooke. However, after exhibiting a few works that were praised by the local press, he was sent to Italy by a group of New York and Philadelphia businessmen for further studies. There he trained with Florentine history painter Pietro Benvenuti. After three years in Europe (1824-7), he returned to New York, where he quickly became a mainstay of the artistic community. In 1831 he was elected to membership in the National Academy of Design in New York, and three years later he was made instructor of drawing at the US Military Academy in West Point, New York, a post he held for the next 42 years.
