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 :. | Leonardo there Vinci and Andrea del Verrocchio, madonna with the child and angels | The embryo in the Uterus | Small devotional picture by Verrocchio | Our Lady and St Anne | Leda h |

Bierstadt Albert
German-born American Hudson River School Painter, 1830-1902 was a German-American painter best known for his large landscapes of the American West. In obtaining the subject matter for these works, Bierstadt joined several journeys of the Westward Expansion. Though not the first artist to record these sites, Bierstadt was the foremost painter of these scenes for the remainder of the 19th century. Bierstadt was part of the Hudson River School, not an institution but rather an informal group of like-minded painters. The Hudson River School style involved carefully detailed paintings with romantic, almost glowing lighting, sometimes called luminism. Bierstadt was born in Solingen, Germany. His family moved to New Bedford, Massachusetts, in 1833. He studied painting with the members of the D??sseldorf School in D'sseldorf, Germany from 1853 to 1857. He taught drawing and painting briefly before devoting himself to painting. Bierstadt began making paintings in New England and upstate New York. In 1859, he traveled westward in the company of a Land Surveyor for the U.S. government, returning with sketches that would result in numerous finished paintings. In 1863 he returned west again, in the company of the author Fitz Hugh Ludlow, whose wife he would later marry. He continued to visit the American West throughout his career. Though his paintings sold for princely sums, Bierstadt was not held in particularly high esteem by critics of his day.

BOL, Hans
Flemish Northern Renaissance Painter, 1534-1593 Hans Bol (1534?C1593), Flemish artist, received his early training from his two uncles who were also painters. He then was the apprentice to a Mechelen watercolorist and tempera painter at the age of fourteen. Because Bol??s watercolors became so widely reproduced, he began creating miniatures on parchment. The technique earned him many international clients and a good income. In addition, Bol also produced several oil paintings, illuminated manuscripts, drawings, and engravings. He preferred to create landscapes, mythological, allegorical and biblical scenes, and genre paintings.
