Leonardo Da Vinci
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.

English, 1824-1905CORNELIUS, Peter
1824-1874,German composer. Trained as actor and violinist, and friend of artists, poets and writers, he devoted himself to music from the 1840s, finding inspiration in Liszt and the New German School at Weimar in 1852. His first mature works were the lieder opp. 1 and 2 and the song cycle Trauer und Trost op.3, followed by the comic opera Der Barbier von Bagdad (1855-8); all show his literary skill, refreshing simplicity and musical independence from the Liszt circle. In Vienna (1859-65), he wrote his second opera Der Cid and enjoyed fruitful relationships with Brahms, Carl Tausig and above all Wagner, who summoned him to Munich in 1865 as his private repetiteur and teacher at the Royal School of Music. His third opera Gunlöd was never finished. He continued to write poetry and essays defending Wagner and Liszt and translated vocal works by Pergolesi, Berlioz, Liszt and others. Although he revered Wagner, he stood ethically and artistically apart, his work (especially Der Barbier) thus representing an original achievement. MOEYAERT, Claes Cornelisz.
Dutch painter (b. 1590/91, Durgerdam, d. 1655, Durgerdam)
Dutch painter, etcher and draughtsman. He was the son of an aristocratic Catholic Amsterdam merchant and moved to the city with his family in 1605. He was the most prolific of the history painters now called the PRE-REMBRANDTISTS, whose representations of biblical and mythological narratives, as well as of more recent secular history, give particular emphasis to dramatic and psychological effects. After working initially as a draughtsman and etcher, Moeyaert soon made his name as a painter. Landscapes with animals feature prominently in both his etchings and his paintings. At first he followed the lead of Adam Elsheimer, then of fellow Pre-Rembrandtists Pieter Lastman and Jan and Jacob Pynas, eventually, in the mid-1630s,
