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 :. | Plan fur a canal to the evasion of the Arno | Female head (La Scapigliata) wt | Annunciation (detail) st | The Madonna of the Carnation (detail) sg | Funf studies of grotesque faces |

Swiss-born French Art Nouveau Painter and Printmaker, 1859-1923 was a Swiss-born French Art Nouveau painter and printmaker. Born in Lausanne, Steinlen studied at the University of Lausanne before taking a job as a designer trainee at a textile mill in Mulhouse in eastern France. In his early twenties he was still developing his skills as a painter when he and his new wife were encouraged by the painter Francois Bocion to move to the artistic community in the Montmartre Quarter of Paris. Once there, Steinlen was befriended by the painter Adolphe Willette who introduced him the artistic crowd at Le Chat Noir that led to his commissions to do poster art for the cabaret owner/entertainer, Aristide Bruant and other commercial enterprises. La tournee du Chat Noir avec Rodolphe Salis (1896)In the early 1890s, Steinlen's paintings of rural landscapes, flowers, and nudes were being shown at the Salon des Independants. His 1895 lithograph titled Les Chanteurs des Rues was the frontispiece to a work entitled Chansons de Montmartre published by Editions Flammarion with sixteen original lithographs that illustrated the Belle Epoque songs of Paul Delmet. His permanent home, Montmartre and its environs was a favorite subject throughout Steinlen's life and he often painted scenes of some of the harsher aspects of life in the area. In addition to paintings and drawings, he also did sculpture on a limited basis, most notably figures of cats that he had great affection for as seen in many of his paintings. Steinlen became a regular contributor to Le Rire and Gil Blas magazines plus numerous other publications including L'Assiette au Beurre and Les Humouristes, a short-lived magazine he and a dozen other artists jointly founded in 1911.
