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 :. | Profiles of a young and an old man | Study Fur the Trivulzio-monument | Mona Lisa (La Gioconda) sdg | Madonna Litta (detail sdg | Virgin of the Rocks |

Francis Bacon
English , 1561-1626 British statesman and philosopher, father of modern scientific method. He studied at Cambridge and at Gray's Inn. A supporter of the Earl of Essex, Bacon turned against him when Essex was tried for treason. Under James I he rose steadily, becoming successively solicitor general (1607), attorney general (1613), and lord chancellor (1618). Convicted of accepting bribes from those being tried in his court, he was briefly imprisoned and permanently lost his public offices; he died deeply in debt. He attempted to put natural science on a firm empirical foundation in the Novum Organum (1620), which sets forth his scientific method. His elaborate classification of the sciences inspired the 18th-century French Encyclopedists, and his empiricism inspired 19th-century British philosophers of science. His other works include The Advancement of Learning (1605),
CORNEILLE DE LYON
Dutch-born French Northern Renaissance Painter, 1500-1575 Dutch painter, active in France. It is uncertain whether he was apprenticed in his native city of The Hague or in Antwerp, and nothing is known of him before 1533, when he was recorded in Lyon. It was possibly in the same year, while the French court was resident in Lyon, that Corneille was made painter to Queen Eleanor, the second wife of Francis I. In 1541 Corneille was painter to the Dauphin (later Henry II), and when the new king succeeded to the throne (1547) and made his state entry into Lyon in 1548, Corneille became Peintre du Roi. Corneille had obtained his naturalization papers in December 1547 and retained French nationality for the rest of his life. He married Marguerite Fradin, the daughter of a Lyon printer of some importance, and this allowed him to enter Lyon society. His studio was extremely prosperous until c. 1565, the year he is known to have visited Antwerp, but disappeared completely after his death despite the fact that he founded a dynasty of painters. His sons Corneille de La Haye II (b 1543) and Jacques de La Haye and his daughter Cl?mence de La Haye were all painters, and the family continued to be known for its artists until the 18th century. Corneille de Lyon was a Protestant, like all those in the circles in which he moved, and it may be that the decline of his fortunes in the 1560s
