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 Adoration of the Magi | Muscle structure of the thigh | Madonna with a Flower | The Virgin of the rocks | La belle Ferronire dg |

Anna Maria Ehrenstrahl
1666-1729,as married Wattrang, (1666-1729), was Swedish painter, the first female painter in her country. She was a baroque-artist and painted allegorys, portraits and group portraits in the style of the Baroque. Born as child of the court painter David Klocker Ehrenstrahl and Maria Momma, she was instructed as a student by her father to copy and finish his works and to paint details and other such smaller things to complete the paintings in his studio. She is confirmed as her fathers assistant from ca 1680. Her learning as an artist was therefore not complete, as he never intended her to become an independent artist, just as a form of artistic secretary in his studio, but she was in fact to create paintings herself eventually. In 1688 she married Johan Wattrang, vice president in Svea Hovratt, and painted six portraits of this courts former presidents, which she gave the court signed with her own name (1717). Her way of painting was in the same barocque style as her father; she painted allergorys and portraits of both single people and groups, bot real people and mytholocigal figures in the style of the time. Among them was portraits of king Charles XI of Sweden, Prince Ulrik (in 1685), an allegory over the four seasons (1687) and an allegory of Cupid and Psyche. She painted the four king's under her lifetime, the Princes Gustaf and Fredrik, Ulrika Eleonora of Denmark and Aurora Konigsmarck.
