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 :. | The Adoration of the Magi | The Last Supper | Study of the proportion of horses | Study fur the head of a Madchens | The annunciation |

John Gadsby Chapman
American Painter, 1808-1889,was an American artist famous for The Baptism of Pocahontas, which was commissioned by the United States Congress and hangs in the United States Capitol rotunda. John Chapman was born in 1808 in Alexandria, Virginia. Chapman began his study of art in Philadelphia for two years, then departed for Europe where he eventually spent time in Italy. In 1831, Chapman returned to his hometown of Alexandria, and exhibited his artwork in the nearest metropolitan areas, such as Washington, D.C., Richmond, and Philadelphia. He specialized in landscapes and portraits. By 1834, Chapman had moved to New York City and become a member of the National Academy of Design, and found work as an illustrator. In New York, Chapman embarked on a series of historic paintings, such as Landing at Jamestown and the Crowning of Powhatan. The success of these paintings helped Chapman land a commission from the United States Congress in February 1837 to paint a historical scene for the rotunda of the Capitol building. For this work, Chapman received a total payment of $10,000. On November 30th, 1840, The Baptism of Pocahontas was formally unveiled in the Capitol rotunda. On the swell of this success, Chapman moved his family to Rome, and made an earnest living selling paintings of rural Campagna to American visitors. However, at the onset of the American Civil War, the tourist industry dried up, affecting Chapman fortunes greatly. In addition, Chapman own son, Conrad Chapman, returned to America to fight on the side of the Confederate States of America. The economic deprivation inflicted on Chapman during the 1860s became insurmountable. In Rome, he was forced to live off the kindness of fellow expatriates, and finally returned to America, sick and poor, to spend his last days with another son, John Linton Chapman, in Brooklyn, New York. It was there, in 1889, that he died a pauper.
