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 | Mona Lisa (detail) dhu | The Virgin and Child with St Anne (detail) s | The Virgin of the rocks | Madonna and Child with a Pomegranate et |

John George Brown
1831-1913 John George Brown Galleries John George Brown (November 11, 1831 - February 8, 1913), American painter, was born in Durham, England, on 11 November 1831. He studied at Newcastle-on-Tyne, in the Edinburgh Academy, and after moving to New York City in 1853, he studied with Thomas Seir Cummings at the schools of the National Academy of Design, of which he became a member in 1863.New International Encyclopedia He was its vice-president, 1899-1904, and originated the idea of the removal of the Academy to a new site in 110th Street. In 1866 he became one of the charter members of the Water-Color Society, of which he was president from 1887 to 1904. He generally confined himself to representations of street child life, bootblacks, newsboys, etc.; his Passing Show (Paris, Salon, 1877) and Street Boys at Play (Paris Exhibition, 1900) are good examples of his popular talent. Brown's art is best characterized as British genre paintings adapted to American subjects. Essentially literary, it is executed with precise detail, but is poor in color, and more popular with the general public than with connoisseurs.
Bill Traylor
African-American Folk Artist, ca.1856-1949 was a self-taught artist born an Alabama slave. Unable to read or write, he first began drawing in 1939 at the age of eighty-three. He worked full-time for the next four years to produce over eighteen hundred drawings. He used a straight edge to create geometric silhouettes of human and animal figures which he then filled in with crayon and tempera. He is known for his intriguing use of pattern versus flat color and a remarkably intuitive sense of space. He started hanging his works on a nearby fence to entertain the locals. One of his first fans was Charles Shannon, a painter who introduced Traylor to the New South regionalist artists and organized two shows of his work before his death. Since then, Traylor has become one of the most highly sought-after outsider artists.
