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 Last Supper | The Annunciation | The Verkundigung | Rule fur the proportion of the human figure | Study fur the adoration of the Konige |

Jozef Chelmonski
(November 7, 1849 - April 6, 1914) was a Polish painter. Chełmoki was born in the village of Boczki near Łowicz in central Congress Poland, Russian Empire. His first drawing teacher was his father (a small leaseholder and administrator of Boczki village). After finishing high school in Warsaw, Jozef studied in Warsaw Drawing Class (1867-1871) and took private lessons from Wojciech Gerson. From 1871 to 1874 Chełmoki lived in Munich. He worked with Polish painters assembled around Jozef Brandt and Maksymilian Gierymski. There, he also studied for a few months at the academy of H. Anschutz and A. Strahuber. In 1872 and 1874 Chełmoki visited the Polish Territories (Poland, as an independent country, did not exist during this time), Tatra Mountains and Ukraine. His first paintings were done under the influence of Gerson. The works that followed were landscapes and villages. In 1875 Chełmoki went to Paris, where he had many important exhibitions and became known to the art scene. With many orders, the artistic level of his paintings decreased. From 1878 to 1887 Chełmoki visited Poland, Vienna and Venice. In 1887 he returned to Poland and in 1889 settled in the village of Kuklewka Zarzeczna. Contact with his homeland and nature are qualities revealed in his artworks. From that time are the best liked, or the most beloved of Chełmoki's paintings are paintings such as Partridge on the Snow, The Storks or Before Thunderstorm. Chełmoki represented the trend in art called "Polish Patriotic Painting". He died in Kuklewka near Grodzisk Mazowiecki in 1914.
