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 :. | Study fur the Sforza-Reiterstandbild | Study fur the communion | Annunciation | The madonna with the Children | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici |

Fritz Petzholdt
(1 January 1805 - 29 August 1838) was a Danish landscape painter of the Copenhagen School, also known as the Golden Age of Danish Painting. He spent most of his artistic life in Italy, where he painted refined landscapes in a light colour palette but died early, most likely by way of suicide. Fritz Petzholdt was born into a prosperous home on 1 January 1805 in Copenhagen to grocer Johan Jacob Petzholdt and his second wife Josephine Marie Elisabeth Petzholdt. After completing an apprenticeship as a house painter, he attended the Royal Danish Academy of Fine Arts from 1824 where he studied under Christoffer Wilhelm Eckersberg, known as the farther of the Golden Age of Danish Painting spanning the first half of the 19th century. He graduated in 1828 and already the following year sold a painting, En mose ved Høsterkøb med tørvearbejdere (A Bog at Høsterkøb), to the Royal Danish Painting Collection. Although he never won the Academy's gold medal, the traditional opening for Academy students to go abroad to further their studies since it was accompanied by a travel stipend, his family's wealth allowed him to travel to Harz the same year and then, in May 1830, to set out for Rome. On the way he visited Dresden, Prague, Nuremberg, Munich, Venice and Florence. In Rome he joined the Danish artists colony which had formed in the city with Bertel Thorvaldsen as its centre. He made excursions to the Roman countrysideeto places such as Tivoli, Subiaco and Olevanoeas well as longer trips south to Naples, Sicily and Corfu. In the winter of 1835/36 he returned to Copenhagen due to his farther's illness and subsequent death. Shortly after the funeral, he returned to Italy with an extended stop in Munich on the way. From Italy he continued to Greece, a destination only Martinus Rørbye had visited before him among the Danish Golden Age painters. On 29 August 1838 he was found dead in his hotel room in Patras with his throat cut. Whether it was a case of suicide or murder was never settled.
