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 Virgin and St Anne (mk08) | Holy Hieronymus | The Annunciation | Ceiling decoration yy | Saint jean-Baptiste |

Anne Vallayer-Coster
French Rococo Era Painter, 1744-1818,was an eighteenth-century French painter. Known as a prodigy artist at a young age, she achieved fame and recognition very early in her career, being admitted to the Royal Academy in 1770, at the age of twenty-six. Despite the negative reputation that still-life painting had at this time, Vallayer-Coster??s highly developed skills, especially in the depiction of flowers, soon generated a great deal of attention from collectors and other artists. Her precocious talent and the rave reviews?? earned her the attention of the court, where Marie Antoinette took a particular interest in Vallayer-Coster's paintings. Regardless of her closeness to the ancient regime and France's hated monarch she survived the bloodshed of the French Revolution. However, the fall of the French monarchy, which were her primary patrons, caused her banishment into the shadows. Anne Vallayer-Coster was a woman in a man??s world. It is unknown what she thought of contemporaries who admitted her to the confraternity, and made her an honorary ??man??. Her life was determinedly private, dignified and hard-working. Occasionally she attempted other genres, but for the usual reasons her success at figure painting was limited
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.
WITTE, Emanuel de
Dutch Baroque Era Painter, ca.1617-1691 Dutch painter. He was one of the last and, with Pieter Saenredam, one of the most accomplished 17th-century artists who specialized in representing church interiors. He trained with Evert van Aelst (1602-57) in Delft and in 1636 joined the Guild of St Luke at Alkmaar, but he was recorded in Rotterdam in the summers of 1639 and 1640. In October 1641 his daughter was baptized in Delft, where he entered the Guild of St Luke in June 1642 and lived for a decade, moving to Amsterdam c. 1652. He began his long career as an unpromising figure painter, as can be seen in the Vertumnus and Pomona (1644) and two small pendant portraits (1648; all Rotterdam, Mus. Boymans-van Beuningen).
