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 | Madonna of the Yarnwinder | Virgin of the Rocks | You branching of the Blutgefabe, anatomical figure with heart kidneys and Blutgefaben | The Virgin and Child with St Anne ey |

Francois de Troy
French Baroque Era Painter, 1645-1730 was a French painter and engraver who became principal painter to King James II in exile at Saint-Germain-en-Laye and Director of the Academie Royale de peinture et de sculpture. One of a family of artists, Troy was born in Toulouse, the son of Nicolas de Troy (1608 - 15 September 1684), a painter in that city,and was the brother of Jean de Troy (4 April 1638 - 25 June 1691).Troy was taught the basic skills of painting by his father, and perhaps also by the more worldly Antoine Durand. François de Troy is not to be confused with his son, the portrait painter Jean-François de Troy (1679-1752), who studied under him At some time after 1662, Troy went to Paris to study portrait painting under Claude Lefebvre (1633-1675) and Nicolas-Pierre Loir (1624 - C1679]. A. P. F. Robert-Dumesnil states that this occurred when Troy was aged twenty-four. In 1669, Troy married his master Nicolas-Pierre Loir's sister-in-law, Jeanne Cotelle. In 1671, he was approved by the Academie Royale de peinture et de sculpture. In 1674, he was received into the Academy as a history painter, with a reception piece (morceau de reception) entitled Mercure coupant la tete d'Argus ('Mercury cutting off the head of Argus'). Troy's early known works include tapestry designs for Madame de Montespan, one of the many mistresses of Louis XIV of France, and paintings with religious and mythological subjects. In the 1670s, he became friendly with Roger de Piles, who introduced him to Dutch and Flemish painting,

helga ancher
född 19 augusti 1883 i Skagen, död 18 mars 1964 i Skagen, var en dansk konstnär (målare). Helga Ancher var dotter till konstnärerna Anna och Michael Ancher och förekommer som barn ofta som motiv i föräldrarnas målningar. Helga kom sedermera själv att utbilda sig till målare och studerade bland annat på Konstakademien i Köpenhamn samt i Tyskland, Frankrike och Italien. Även om hon aldrig blev blev lika känd för sin konst som sina föräldrar har en del av hennes tavlor kommit att betinga höga värden på auktioner. Föräldrarnas hem i Skagen lät Helga Ancher efter moderns död 1935 bevara i det skick det hade då och skänkte sedermera detta till en stiftelse, vilken 1967 kunde öppna konstnärsbostaden som museum.
