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 | Benois Madonna | Muscle structure of the thigh | The Last Supper sgu | Annunciation (detail) sg77 |

Jan van Goyen
1596-1656 Dutch Jan van Goyen Galleries Dutch landscape painter. He studied at Leiden and Haarlem. In 1631 he settled at The Hague. His typically Dutch landscapes of harbors, canals, riverbanks, and winter scenes with skaters and sleighs are naturalistically painted in a grayish-green tonality. He was one of the first landscape painters to sacrifice minute detail for atmospheric effect and space, and he had a considerable influence on later Dutch landscapists. His paintings are in many collections in Europe and the United States. Famous examples are Panorama of The Hague (The Hague); Banks of a Canal (Louvre); and View of Dordrecht (Rijks Mus.). The Metropolitan Museum has five of van Goyen's works, and the Pennsylvania Academy, two.

William Trost Richards
(June 3, 1833 - April 17, 1905) was an American landscape artist associated with both the Hudson River School and the American Pre-Raphaelite movement. William Trost Richards was born on 3 June 1833 in Philadelphia. In 1846 and 1847 he attended the local Central High School. Between 1850 and 1855 he studied part-time with the German artist Paul Weber while working as designer and illustrator of ornamental metalwork. Richards first public showing was part of an exhibition in New Bedford, Massachusetts, organized by artist Albert Bierstadt in 1858. In 1862 he was elected honorary member of the National Academy of Design and Academician in 1871. In 1863, he became a member of the Association of the Advanced of Truth in Art, an American Pre-Raphaelite group. In 1866, he departed for Europe for one year. Upon his return and for the following six years he spent the summers on the East Coast. In the 1870s, he produced many acclaimed watercolor views of the White Mountains, several of which are now in the collection of the Metropolitan Museum of Art. Richards exhibited at the National Academy of Design from 1861 to 1899 and at the Brooklyn Art Association from 1863 to 1885. He was elected a full member of the National Academy in 1871. Richards rejected the romanticized and stylized approach of other Hudson River painters and instead insisted on meticulous factual renderings. His views of the White Mountains are almost photographic in their realism. In later years, Richards painted almost exclusively marine watercolors. His works are featured today in many important American museums, including the National Gallery, the Smithsonian American Art Museum, the Wadsworth Atheneum, the Philadelphia Museum of Art, the Yale University Art Gallery, the High Museum of Art, the Museum of Fine Arts, Boston, the Fogg Art Museum, the Brooklyn Museum of Art and the Thyssen-Bornemisza Museum.
