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 :. | Power and ortraits | Hi Hieronymus | Last Supper (mk08) | The annunciation | Madonna with the Yarnwinder |

George Thomas
1816-1870 Union general in the American Civil War, b. Southampton co., Va. He served in the Seminole War and in the Mexican War. Later he taught at West Point and served in Texas. As a brigadier general of volunteers, he was sent to Kentucky, where he defeated the Confederates at Mill Springs (Jan., 1862). Thomas served under General Buell at Shiloh, Corinth, and Perryville. In the Chattanooga campaign, his stand on Sept. 20, 1863, which saved the Union army from complete rout, won for him the sobriquet Rock of Chickamauga. Appointed brigadier general in the regular army, he succeeded General Rosecrans in command of the Army of the Cumberland (Oct., 1863) and served under Ulysses S. Grant around Chattanooga and under General Sherman in the Atlanta campaign. With the fall of Atlanta (Sept., 1864), Grant ordered Thomas to pursue the army of General Hood into Tennessee. Although accused by Grant of moving too slowly, and threatened with the loss of his command, Thomas waited and finally defeated Hood at Nashville (Dec., 1864).
Pier Leone Ghezzi
(Rome, 28 June 1674 - Rome, 6 March 1755) was an Italian Rococo painter and caricaturist active in Rome. Caricature of composer Antonio Vivaldi by Pier Leone GhezziGhezzi was born in Rome. His father, Giuseppe Ghezzi, (1634-1721), also trained Antonio Amorosi, and was a secretary to the Roman Accademia di San Luca. Pier Leone himself joined the Academy in 1705 and he executed a painting, the Allegory of Gratitude, to be donated to the institution, as was customary. He was the godson of Carlo Maratta. Pier Leone is known for his frescoes in the Villa Falconieri of Frascati. His pen and gouache caricatures are much freer in emotion than his state portraiture, and often depict named individuals or professions in satirical fashion.
Duccio
1255-c1319 Italian Duccio Location Italian painter. He was one of the most important painters of the 14th century and like his slightly younger contemporary, Giotto, was a major influence on the course of Italian painting. An innovator, he introduced into Sienese painting new altarpiece designs, a dramatic use of landscape, expressive emotional relationships, extremely complex spatial structures and a subtle interplay of colour. His most important and revolutionary work, the Maeste for Siena Cathedral, was never matched during the 14th century, if at all, and his influence lasted well into the 15th century.
