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 :. | Unfinished painting of St. Jerome in the Wilderness | Anatomy of the Schadels | The Virgin and St Anne (mk08) | The Virgin and the Nino with Holy Ana | Madonna and Child with a Pomegranate et |

Cassius Marcellus Coolidge
(September 18, 1844?CJanuary 13, 1934) was an American artist, best known for a series of nine paintings of anthropomorphized dogs. Born in upstate New York to abolitionist Quaker farmers, Coolidge was known to friends and family as "Cash." While he had no formal training as an artist his natural aptitude for drawing led him to create cartoons for his local newspaper when in his twenties. He is credited with creating Comic Foregrounds, life-size cutouts into which one's head was placed so as to be photographed as an amusing character. In 1903, Coolidge contracted with the advertising firm of Brown & Bigelow of St. Paul, Minnesota, to create sixteen oil paintings of dogs in various human poses.
Charles Altamont Doyle
1832-1893 was a Victorian artist. He was the brother of the artist Richard Doyle, and the son of the artist John Doyle. Although the family was Irish, Doyle was born and raised in England. In 1849 he moved to Edinburgh where he met Mary Foley. They were married on 31 July 1855. Their children included Arthur Conan Doyle, creator of Sherlock Holmes, John Francis Innes Hay Doyle (known as Innes or Duff), and Jane Adelaide Rose Foley n??e Doyle (known as Ida). Doyle was not as successful an artist as he wished, and suffered depression and alcoholism. His paintings, which were generally of fairies, such as "A Dance Around The Moon", or similar fantasy scenes, reflected this, becoming more macabre over time. In 1881 Doyle was committed to a nursing home specialising in alcoholism. While there, his depression grew worse, and he began suffering epileptic seizures. Following a violent escape attempt he was sent to Sunnyside, Montrose Royal Lunatic Asylum, where he continued to paint. He died in Crighton Royal Institution in 1893.
