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 :. | Leda h | Madonna Litta (detail sdg | Mona Lisa (detail) dyk | Grotesque profile of a man | Study fur the communion |

Henri Felix Emmanuel Philippoteaux
(1815-1884) was a French artist. He was born in Paris, France, studied art at the studio of Leon Cogniet,and first exhibited his work at the Paris Salon of 1833. One of his most well-known works was a depiction of the Siege of Paris during the Franco-Prussian War, painted in the form of a cyclorama, a type of large panoramic painting on the inside of a cylindrical platform designed to provide a viewer standing in the middle of the cylinder with a view of the painting. Viewers surrounded by the panoramic image are meant to feel as if they are standing in the midst of a historic event or famous place. Philippoteaux also produced a large number of works chronicling the rise and successes of Napoleon Bonaparte, including a portrait of Napoleon in his regimental uniform and a group of paintings of French victories in the Napoleonic Wars. Philippoteaux was awarded the Legion d'honneur in 1846. Philippoteaux's son Paul Philippoteaux was also an artist; both were famous for their production of cycloramas. Father and son collaborated on The Defence of the Fort d'Issy in 1871.
Martin, Henri
French Post-Impressionist Painter, 1860-1943 French painter. After winning the Grand Prix at the Ecole des Beaux-Arts in Toulouse, he moved to Paris (1879) to study at the Ecole des Beaux-Arts there under Jean-Paul Laurens, who encouraged his interest in Veronese and other Venetian painters. The literary inspiration of his early work was reflected in such paintings as Paolo de Malatesta and Francesca da Rimini in Hell (1883; Carcassonne, Mus. B.-A.) based on Dante, for which he won a medal at the Salon of 1883. During his subsequent study in Rome, however, on a fellowship awarded to him at the Salon,
Frans Post
1612-1680 Dutch Frans Post Gallery was a Dutch painter. He was the first European artist to paint landscapes of the New World. In 1636 he traveled to Dutch Brazil at the invitation of Johan Maurits van Nassau-Siegen, who was governor-general there, at the suggestion of his brother Pieter Post. In 1644, Post returned to Haarlem. Of his Brazilian landscapes, some depict actual locations, while others are probably imaginary. Post's art is usually classified as Baroque.
