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 :. | Annunciation (detail) ey79 | Leda | Battle of Anghiari | Rule fur the proportion of the human figure | Annunciation (detail) sg77 |

Ralph Albert Blakelock
(October 15, 1847 - August 9, 1919) was a romanticist painter from the United States. Ralph Blakelock was born in New York City on October 15, 1847. In 1864, Blakelock entered the Free Academy of the City of New York (now known as the City College) with aspirations of becoming a physician. After his third term he opted to dismiss his formal education and left college. From 1869-71 he traveled west, extensively wandering far from known civilization and spending time among the American Indians. Largely self-taught as an artist, he began producing competent landscapes, depicting select views from his travels, as well as scenes of American Indian life. His works were exhibited in the National Academy of Design. Moonlight, 1885, the Brooklyn MuseumIn 1877 Blakelock married Cora Rebecca Bailey; they had nine children. In art, Blakelock was a genius, yet, in business dealings and in monetary transactions he proved a failure. He found it difficult, if not crushing to maintain and support his wife and children. In desperation he found himself selling his paintings for extremely low prices, far beneath their known worth. In hopes of lifting his family from abject poverty, reportedly on the day his 9th child was born, Blakelock had offered a painting to a collector for $1000. The collector made a counter offer and after refusing the proposed sum Blakelock found himself in a bitter argument with his wife. After the domestic dispute, Blakelock returned to the patron and sold the painting for a much lesser sum. Defeated and frustrated, it is said he broke down and tore the cash into pieces. And so it was after such repeated failed business transactions that he began to suffer from extreme depression and eventually show symptoms of mental frailty. In 1899 he suffered a breakdown.
Henry Walton
British Painter , c 1746-1813 He studied in London under Johan Zoffany c. 1769, after which he completed his training at the Maiden Lane Academy. It was probably Zoffany who introduced Walton to the conversation piece, a genre in which he was to specialize. The Cricket Scene at Harrow School (1771; priv. col., see 1963 exh. cat., no. 1) reveals Walton's debt to Zoffany, but it also shows him to be an exceptional colourist and able to compose his figures with a sense of rare warmth and intimacy.
