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 :. | St John in the Wilderness | The Baptism of Christ | Study fur the Sforza-Reiterstandbild | The Last Supper sgu | Madonna with the Yarnwinder ty |

Adolf Ulrik Wertmuller
(February 18, 1751 e October 5, 1811) was a Swedish painter whose notable works include Danaë receiving Jupiter in a Shower of Gold. Wertmeller was born in Stockholm and studied art at home before moving to Paris in 1772 to study under his cousin Alexander Roslin and French painter Joseph-Marie Vien. On July 30, 1784, Wertmeller was elected to the Royal Academy of Painting and Sculpture. Wertmeller was commissioned by Gustav III of Sweden for a portrait of Marie Antoinette, which is now in the Nationalmuseum at Stockholm. In 1787, he produced his masterpiece Danaë, a work which proved controversial as one of the earliest female nude paintings exhibited in America. Wertmeller first emigrated to the United States in May 1794 and continued his portrait work, most notably of General George Washington, but in 1796 was called back to Sweden, eventually returning to Philadelphia in 1800. Elizabeth B. Johnston, in her book Original Portraits of Washington (Boston, 1882), speaks of five portraits of Washington by Wertmeller, of which one, executed in 1797, was purchased by the U. S. government in 1878, and another is owned by the Historical Society of Pennsylvania. Wertmeller was married to Elizabeth Henderson, granddaughter of noted early American painter Gustavus Hesselius, on January 8, 1801, and two years later retired to a plantation in Claymont, Delaware, where he lived the final years of his life. He died near Marcus Hook, Pennsylvania, aged 60.
Sarah Miriam Peale
(Philadelphia, Pennsylvania, May 19, 1800 - February 4, 1885, Philadelphia) was an American portrait painter, one of the notable family of artists descended from the miniaturist and still-life painter James Peale, who was her father. She is noted as a portrait painter, mainly of politicians and military figures. Lafayette sat for her four times. Sarah was James Peale's youngest daughter and was trained by her father, and uncle Charles Willson Peale. She served as a studio assistant to her father. Her first public works date from 1816 with subjects such as flowers and still-life but soon turned to portraiture, In 1818, she spent three months with Rembrandt Peale, her cousin, in Baltimore, and again in 1820 and 1822. He influenced her painting style and subject matter. For 25 years, she painted in Baltimore (1822-47) and, intermittently, in Washington, D.C. She was accepted to the Pennsylvania Academy of Fine Arts in 1824 along with her sister Anna Claypoole Peale, the first women to achieve this distinction. Over 100 commissioned portrait paintings are known from her time in Baltimore and she was the most prolific artist in the city during that era. Her subjects were wealthy Baltimore residents and politicians from Washington DC.
