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 Child with St Anne | The Annunciation | Abendmahl | Study fur the Trivulzio-monument | Equestrian monument |

Carl Oscar Kylberg, född 23 september 1878 på Vasängen i Fridene församling, död 6 januari 1952 i Stockholm, svensk konstnär och representant för Göteborgskoloristerna. Carl Kylberg var son till kontorschef Gustaf Kylberg och friherrinnan Eleonora von Essen och storebror till konstnären Erik Kylberg. Hans fastrar och farbror var konstnärerna Regina Kylberg-Bobeck, Marina Kylberg och Hjalmar Kylberg. Farfadern Lars Wilhelm Kylberg var konstnär vid sidan av lantbruket på familjegodset Såtenäs i Västergötland. Kylberg studerade först vid tekniska skolan i Stockholm och i Berlin för att bli arkitekt men övergick till måleri omkring 1900. Han studerade under en tid vid Valand i Göteborg som elev till Carl Wilhelmson. Hans verk kännetecknas ofta av ett glödande oljemåleri med starka färger och han avbildade ofta landskap och figurkompositioner på ett avskalat man??r. Under senare delen av sitt konstnärskap skapade han en mängd religiösa motiv. Kring 1930-talet fick han sitt genombrott och han kom att ställa ut, förutom i Sverige även i Köpenhamn, Paris, London, Budapest och i USA men hans måleri var för många provocerande och 1938 gick regeringen in och stoppade ett köp av målningen Uppbrottet för Nationalmuseum i Stockholm. En av hans mest välkända målningar är Hemkomsten från 1938 som hänger på Göteborgs konstmuseum och som föreställer ett skepp i silhuett mot en nästan brinnande gul himmel och ett rödfärgat hav. Denna målning förevigades också 1978 på ett svenskt frimärke av valören 90 öre. Sedan 1980-talet har många av hans tavlor sålts för rekordpriser vid olika internationella konstauktioner.
