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 :. | Mona Lisa | Study Fur the Trivulzio-monument | Profile one with book leaves gekroten of old man | Small devotional picture by Verrocchio | Madonna Litta ey |

Grigoriy Soroka
(Russian, real surname Vasilyev. November 27 [O.S. November 15] 1823-April 22 [O.S. April 10] 1864) was a Russian painter, one of the most notable members of Venetsianov school. Soroka was born in Pokrovskoye village (Tver Guberniya), in the family of landowner Milyukov. In 1842-1847 he studied art from Alexey Venetsianov then he was returned to his owner. In 1850s-1860s he resided in his home village. He fell in love with his owners's daughter Lydia but was forcibly married to a serf woman. After the emancipation reform of 1861 in Russia, Soroka remained under the serfdom system. He made a formal complaint but it was rejected and he was flogged. Soroka's body was found in the baking room where he had hanged himself. His beloved Lydia poisoned herself soon after.
Hans Olaf Heyerdahl
Swedish, 1857-1913 Norwegian painter. He was born into an enlightened but conservative family, his father being an engineer, occasional architect and writer of Nordic saga poetry, and he spent his childhood and youth in the rapidly expanding town of Drammen, 40 km from the capital Christiania. In 1873 he was admitted to the Kongelige Tegneskole in Christiania, where he studied under Peder C. Thurmann, a landscape artist trained in Desseldorf. For more advanced training, Heyerdahl was obliged to go abroad, and in 1874 he enrolled at the Munich Akademie. He was encouraged by Professor Ludwig von Lefftz (1845-1910) to give up landscape in favour of history painting and portraits (e.g. the artists Christian Skredsvig, 1876, and Eilif Peterssen, 1877; both Oslo, N.G.). In 1877, under the guidance of Professor Wilhelm Lindenschmit (1829-95), Heyerdahl finished his most inventive and brilliant composition, the Expulsion from the Garden (Oslo, N.G.). Using over life-size figures, set in a barren tempestuous landscape, Heyerdahl skilfully contrasted the youthful rage of Adam with the resigned despair of Eve. This sombre work won him a third prize medal at the Exposition Universelle in Paris in 1878.
