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 Last Supper | The Madonna of the Carnation (detail) sg | Madchenkopf with confused hair | Portrait de femme,dit a tort La belle ferronniere | Head and shoulders Christs |

Diego Velazquez
Spanish Baroque Era Painter, 1599-1660 Spanish painter. He was one of the most important European artists of the 17th century, spending his career from 1623 in the service of Philip IV of Spain. His early canvases comprised bodegones and religious paintings, but as a court artist he was largely occupied in executing portraits, while also producing some historical, mythological and further religious works. His painting was deeply affected by the work of Rubens and by Venetian artists, especially Titian, as well as by the experience of two trips (1629-31 and 1649-51) to Italy. Under these joint influences he developed a uniquely personal style characterized by very loose, expressive brushwork. Although he had no immediate followers, he was greatly admired by such later painters as Goya and Manet
Rudolf von Alt
(28 August 1812 in Vienna C 12 March 1905 in Vienna) was an Austrian landscape and architectural painter. Borne as Rudolf Alt, he could call himself von Alt and bear the title of a Ritter (knight) after he gained nobility in 1882. He was the son of the famous lithographer Jakob Alt (1789-1872). He studied at the Akademie der bildenden K??nste in Vienna. Hiking-trips through the Austrian Alps and northern Italy awoke a love for landscapes, and he painted with his brush using watercolors in a very realistic and detailed style. In 1833, inspired by a visit to Venice and neighbouring cities, he also made a number of architectural paintings. Alt demonstrated a remarkable talent for expressing certain peculiarities in nature. He managed to paint nature authentically by focusing on the different hues of sky, the colour-tone of the air and the vegetation. His later works came closer to Impressionism. His perspectives on architecture were interesting, and he often chose everyday objects to paint. The painting of interior-views also became one of his strong points, giving him attention in Vienna.
