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 :. | Madonna in the rock grottos | Mona Lisa | The Virgin and Child with St Anne (detail) s | the last supper | Anatomical drawing of the stomach and the intestine |

Anne-Louis Girodet-Trioson
1767-1824 French Anne Louis Girodet Trioson Galleries Girodet was born at Montargis. He lost his parents in early youth and the care of his inheritance and education fell to his guardian, M. Trioson, "medecin-de-mesdames," by whom he was in later life adopted and whose surname he took in 1812. He started in school by studying architecture and pursuing a military career. He later changed to the study of painting under a painter named Luquin, before entering the school of David. From 1789 to 1793 he lived in Italy where, at the age of twenty-two, he successfully competed for the Prix de Rome thus making a name for himself for his painting of the Story of Joseph and his Brethren. At Rome he painted his Hippocrate refusant les presents d'Artaxerxes and Endymion-dormant (presently held in the Louvre), work which was praised at the Salon of 1793.

He was a student of Vecchietta, and then he shared a workshop with Francesco di Giorgio from 1468.

Charles S. Dorion
Charles was most likely born in Quebec, Canada, and moved to New York City sometime after 1880. He had a publishing company called C.S. Dorion, and was the 8th company to publish Edgar Allan Poe's the Raven, in New York in 1881. PoliticsDuring the 1890s, Charles Dorian socialized with New York City's Social Democratic Party's elite, and used his quick tongue and self appointed crusading against injustice to help propel his friends political careers. His first noted case was in the summer of 1893, when bucket shops were becoming a rampant problem in the city, as these "bucket shops" specializing in stocks and commodity futures, as the terms of trade were different for each bucket shop.
