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 Annunciation | Plan fur a canal to the evasion of the Arno | Madonna in the rock grottos(Details | The organs of the woman | la scapigliata |

CODDE, Pieter
Dutch Baroque Era Painter, 1599-1678 Dutch painter and poet. Frans Hals was once thought to have been his teacher, but there is no evidence for this. It is possible that Codde studied with a portrait painter, perhaps Barent van Someren (1572/3-1632) or Cornelis van der Voort (1576-1624), since most of his earliest works, from the period 1623-7, seem to be portraits. His earliest known dated work is the Portrait of a Young Man (1626; Oxford, Ashmolean), which precedes by a year his earliest dated genre piece, the Dancing Lesson (1627; Paris, Louvre). He was particularly productive in the 1620s and 1630s, painting mainly interior genre scenes. After the mid-1640s only portraits and a few history paintings, such as the Adoration of the Shepherds
Jules Tavernier
1844-1889 Jules Tavernier was born in Paris in 1844. He studied with the French painter, F??lix Joseph Barrias (1822-1907), but left France in the 1870s, never to return. Tavernier was employed as an illustrator by Harper's Magazine, which sent him on assignment to California in the 1870s. Eventually he continued westward to Hawaii, where he made a name for himself as a landscape and portrait painter. He was captivated by Hawaii??s erupting volcanoes??a subject that was to pre-occupy him for the rest of his life, which was spent in Hawaii, Canada and the western United States. He is considered the most important artist of Hawaii??s Volcano School. Tavernier died in Honolulu, Hawaii in 1889. His students included David Howard Hitchcock (1861-1943), Am??d??e Joullin (1862-1917), Charles Rollo Peters (1862-1917) and Manuel Valencia (1856-1935). The Honolulu Academy of Arts and the Stark Museum of Art (Orange, Texas) are among the public collections having paintings by Jules Tavernier.
