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 :. | Studies fur the adoration of the Konige | Study Fur the Trivulzio-monument | Portrait of a Musician dey | The master of the Pala Sforzesca attributed | virgin and child with st.anne |

Ludolf Bakhuizen
(December 28, 1630 - November 17, 1708) was a German-born Dutch Golden Age painter who was the leading Dutch painter of maritime subjects after the two Willem van de Veldes (father and son) left for England in 1672. He was born in Emden, East Frisia, and came to Amsterdam in about 1650, working as a merchant's clerk and a calligrapher. He discovered so strong a genius for painting that he relinquished the business and devoted himself to art from the late 1650s, initially in pen drawings. He studied first under Allart van Everdingen and then under Hendrik Dubbels, two eminent masters of the time, and soon became celebrated for his sea-pieces, which often had rough seas. He was an ardent student of nature, and frequently exposed himself on the sea in an open boat in order to study the effects of storms. His compositions, which are numerous, are nearly all variations of one subject, the sea, and in a style peculiarly his own, marked by intense realism or faithful imitation of nature. In his later years Bakhuizen employed his skills in etching; he also painted a few examples each of several other genres of painting, such as portraits, landscapes and genre paintings.

American Sculpture 1863-1937,American sculptor and painter. During his apprenticeship in New York (1880-84) with Augustus Saint-Gaudens, who discovered and encouraged his talent, he rose from menial helper to assistant, studying in the evenings at Cooper Union and the National Academy of Design. Through Saint-Gaudens he met two architects who later became invaluable colleagues: Stanford White and Charles F. McKim, who lent him money in 1884 to go to Paris. He studied drawing at Colarossi's then went to Munich, attending drawing and portrait classes at the Akademie (1884-5) and worked for Saint-Gaudens again (1885-6). In Paris he studied sculpture with Alexandre Falguiere at the Ecole des Beaux-Arts,
