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 :. | Adoration of the Magi (mk08) | The Refectory with the Last Supper after restoration g | Knieened figure in Draperie | Leda and the Swan | The Virgin and Child with St Anne ey |

Gilbert Charles Stuart
1755-1828 Gilbert Charles Stuart Locations Gilbert Charles Stuart (born Stewart) (December 3, 1755 ?C July 9, 1828) was an American painter from Rhode Island. Gilbert Stuart is widely considered to be one of America's foremost portraitists. His best known work, the unfinished portrait of George Washington that is sometimes referred to as The Athenaeum, was begun in 1796 and left incomplete at the time of Stuart's death in 1828. The image of George Washington featured in the painting has appeared on the United States one-dollar bill for over one century. Throughout his career, Gilbert Stuart produced portraits of over 1,000 people, including the first six Presidents of the United States. His work can be found today at art museums across the United States and the United Kingdom, most notably the Metropolitan Museum of Art in New York City, the National Gallery of Art in Washington, D.C., the National Portrait Gallery in London, and the Museum of Fine Arts in Boston.
Henri-Pierre Picou
(27 February 1824 - 17 July 1895) was a French painter born in Nantes.His oeuvre began with portraits and classical historical subject matter but he later moved on to allegorical and mythological themes.He was an academic painter and one of the founders of the Neo-Grec school, along with his close friends Gustave Boulanger, Jean-L??on G??rôme, and Jean-Louis Hamon, also academic painters. All of them studied in the workshops of both Paul Delaroche and later Charles Gleyre. Picou's style was noticeably influenced by Gleyre. While the rest of the group generally painted classical and mythological subjects, Picou also received commissions for large religious frescoes from many churches, including the Église Saint-Roch. His artistic debut was at the Salon in 1847. The next year he was awarded a second-class medal for his painting, Cl??opâtre et Antoine sur le Cydnus. Also known as Cleopatra on the Cydnus, it is commonly regarded as Picou's masterpiece. This showing at the Salon in 1848 was written about by the critic Th??ophile Gautier, who felt that the subject matter was too ambitious, but also said that "As it is, it gives the best hope for the future of the young artist, and ranks among the seven or eight most important paintings of the Salon.In 1875 the painting was exhibited in New York, and afterward found lodgment on the walls of a private art gallery in San Francisco.Picou maintained a large workshop in Paris on the Boulevard de Magenta, which provided him room to work on his expansive frescoes. His popularity continued to rise and he went on to win the Second Prix de Rome in 1853 for his painting, J??sus chassant les vendeurs du Temple (The Moneylenders Chased from the Temple), and another second-class medal for his Salon painting in 1857. From his debut in 1847, he was a regular at the Salon, showing almost every year until his final exhibit in 1893.He has been called the most fashionable painter towards the close of the Second French Empire
