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 last supper | Hl.

Thomas Hill
1829-1908 Thomas Hill was born in England on September 11, 1829. At the age of 15, he emigrated to the United States with his family. They settled in Taunton, Massachusetts. In 1851, he married Charlotte Elizabeth Hawkins. They had nine children. At the age of 24, Hill attended evening classes at the Pennsylvania Academy of the Fine Arts (PAFA) and studied under American painter Peter Frederick Rothermel (1812-1895). During his years as a student, Hill traveled to the White Mountains in New Hampshire as early as 1854 and sketched alongside members of the Hudson River School, such as Benjamin Champney. In 1856, Hill and his family moved to San Francisco, California. With painter Virgil Williams and photographer Carleton Watkins, Hill made his first trip to the Yosemite Valley in 1865. The next year, Hill traveled to the East Coast and Europe. He established his family on the East Coast but continued to take sketching trips to the West Coast and to attend meetings of the San Francisco Art Association. He moved his family back to San Francisco in 1873. Hill made yearly sketching trips to Yosemite, Mount Shasta, and, back east, to the White Mountains. Hill ran an art gallery and art supply store. He briefly acted as the interim director for the SFAA School of Design and went to Alaska on a commission for environmentalist John Muir. He lived on his stock market investments as well as his art proceeds. His marriage ended in the 1880s. Toward the end of his life, he maintained a studio at Yosemite??s Wawona Hotel. After suffering a stroke, Hill left Yosemite and traveled up and down the California coast, including stops in Coronado, San Diego and Santa Barbara. He died in Raymond, California, on June 30, 1908, and is buried at Mountain View Cemetery in Oakland, California.

CASTELLO, Valerio
Italian painter, Genoese school (b. 1624, Genova, d. 1659, Genova) Painter and draughtsman, son of Bernardo Castello. He was one of the leading Ligurian painters of the 17th century, whose art developed from a continuous and passionate study of a wide range of sources. His paintings of mythological and religious subjects unite an elegant figure style with an interest in dramatic and violent compositions; his touch is spontaneous and his palette vibrant with reds and pinks, blues and yellows. His brilliant decorative frescoes introduced the splendour of the High Baroque to Genoese painters. He was well known for his rapid oil sketches, with light and lively brushwork, which anticipate aspects of the Rococo.
