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 :. | Reverse side of the portrait of Ginevra de' Benci | Last Supper (mk08) | St John the Baptist t | A full-scale composition of the Virgin and Child with St Anne and the infant St John the Baptist | Leda and the Swan |

Ivan Bilibin
(Russian, 16 August [O.S. 4 August] 1876 - 7 February 1942) was a 20th-century illustrator and stage designer who took part in the Mir iskusstva and contributed to the Ballets Russes. Throughout his career, he was inspired by Slavic folklore. Ivan Bilibin was born in a suburb of St. Petersburg. He studied in 1898 at Anton Ažbe Art School in Munich, then under Ilya Repin in St. Peterburg. In 1902-1904 Bilibin travelled in the Russian North, where he became fascinated with old wooden architecture and Russian folklore. He published his findings in the monograph Folk Arts of the Russian North in 1904. Another influence on his art was traditional Japanese prints. Bilibin gained renown in 1899, when he released his illustrations of Russian fairy tales. During the Russian Revolution of 1905, he drew revolutionary cartoons. He was the designer for the 1909 premiere production of Nikolai Rimsky-Korsakov's The Golden Cockerel. The October Revolution, however, proved alien to him. After brief stints in Cairo and Alexandria, he settled in Paris in 1925. There he took to decorating private mansions and Orthodox churches. He still longed for his homeland and, after decorating the Soviet Embassy in 1936, he returned to Soviet Russia. He delivered lectures in the Soviet Academy of Arts until 1941. Bilibin died during the Siege of Leningrad.
