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 embryo in the Uterus | The Last Supper | Anatomy of the Schadels | Virgin of the Rocks | Profile one with book leaves gekroten of old man |

Hedvig Eleonora av Holstein-Gottorp, född 23 oktober 1636, död 24 november 1715, var svensk drottning och riksföreståndare, dotter till Fredrik III av Holstein-Gottorp och Marie Elisabeth av Sachsen och gift i november 1654 med Karl X Gustav. Hon var med honom i Polen 1656 och i Danmark 1658. Hon var Sveriges drottning i sex år, men de facto "första dam" till sin död 1715, i femtiofem års tid. Hon blev änka 1660 och levde som änkedrottning i ytterligare 55 år. Kung Karl II av England friade till henne något år efter makens död, men hon tackade nej, med den formella motiveringen att hon önskade vara sin döde make evigt trogen. Hon satt i förmyndarregeringarna för både sin son Karl XI och sin sonson Karl XII, 1660-1672 samt 1697, och sedan i rådet 1700-1713, men hade i verkligheten aldrig så mycket att göra med politik, utan var nöjd med att formellt presidera över regeringen och hovet som monarkins symboliska överhuvud och representant. Hon stödde dock den profranska och antidanska policy som fördes av regenterna. Hennes son var djupt beroende av henne i hela sitt liv; då han blev gammal nog att sitta med vid regeringens sammanträden, talade han inte direkt till ledamöterna, han viskade i stället vad han ville veta till riksänkedrottningen, och Hedvig Eleonora frågade sedan regeringen med hög röst vad han ville veta. Då sorgeperioden formellt bröts år 1663 var hon värdinna för omfattande festligheter, och det var i hennes namn Sveriges första fasta teater öppnades i Stora Bollhuset och Lejonkulan 1667. Hedvig Eleonora, "Riksänkedrottningen", hade en dominant och temperamentsfull personlighet och dominerade det svenska hovet totalt fram till sin död. Även efter sin sons giftermål 1680 och fram till sin död 1715 var hon den verkliga drottningen och behöll sin position som "första dam"; sonen kallade henne "drottningen" och sin fru för "min fru". Under stora nordiska kriget var hon 1700-13 representant för kungen, men intresserade sig inte heller nu mycket för politik- vid audienser för utländska sändebud kunde antingen "moltiga" eller gapskratta åt dem. Hon intresserade sig för kortspel och arkitektur. Hon kunde spela kort till inpå småtimmarna. Drottningholms slott samt Strömsholms slott påbörjades av henne. Vid båda slotten lät hon anlägga stora parker i tidens stil.
