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 :. | Salai as John the Baptist | Portrait de Mona Lisa dit La joconde | Virgin of th Rock (mk08) | La Vierge,l'Enfant Jesus et sainte Anne | Small devotional picture by Verrocchio |

Vasily Grigorevich Perov (Russian; real name Vasily Grigorevich Kridener ; 2 January 1834 (21 December 1833 Old Style) - 10 June (29 May Old Style) 1882) was a Russian painter and one of the founding members of Peredvizhniki, a group of Russian realist painters. Vasily Perov was born 2 January 1834 (21 December 1833 Old Style) in Tobolsk, being the illegitimate son of procurator, baron Grigory Karlovich Kridener. After completing a course at Arzamas uezd school, he was transferred to the Alexander Stupin art school also located in Arzamas. In 1853 he was admitted to the Moscow School of Painting, Sculpture and Architecture, where he learned from several renowned artists. In 1856 he was awarded with a minor silver medal for his sketch of a boy's head, presented to the Imperial Academy of Arts. Later the Academy gave him many other awards: in 1857 a major silver medal for Commissary of Rural Police Investigating, a minor golden medal for the Scene on a Grave and the Son of a Dyak Promoted to First Rank, and in 1861 a major golden medal for Sermon in a Village. After receiving the right to a state-paid trip abroad together with a golden medal, in 1862 Perov went to Western Europe, visiting several German cities, and then Paris. During this time he created paintings depicting scenes from European street life, such as the Vendor of statuettes, the Savoyard, the Organ-Grinder in Paris, the Musicians and the Bystanders, and the Paris Ragpickers. Returning to Moscow early, from 1865 to 1871 Perov created his masterpieces The Queue at The Fountain, A Meal in the Monastery, Last Journey, Troika, the Lent Monday, Arrival of a New Governess in a Merchant House, the Drawing Teacher, A Scene at the Railroad, the Last Tavern at Town Gate, the Birdcatcher, the Fisherman, and the Hunters at Rest.
