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 :. | Small devotional picture by Verrocchio | Mona Lisa | The Fotus in the Uterus | Adoration of the Magi | The adoration of the Konige |

Levitsky, Dmitry
Russian Painter, 1735-1822 .Russian painter of Ukrainian birth. Together with Fyodor Rokotov and Vladimir Borovikovsky, he ranks foremost among 18th-century Russian portrait painters. He received his first lessons in painting from his father, Grigory Levitsky-Nos (1697-1769), a priest, engraver and painter. He also studied under Aleksey Antropov, who had come to Kiev to decorate St Andrew's church (1752-5). In the late 1750s Levitsky went with Antropov to St Petersburg, where he stayed until 1764; he continued with lessons from Antropov to whom, it appears, he owed the objectivity that was to characterize his work. It is probable that he also studied at the St Petersburg Academy of Arts, attending classes under Louis Lagren?e. Levitsky worked with Antropov on the decoration of triumphal arches in Moscow for Catherine II's coronation in 1762. His first known portraits are rather formal, for example that of the architect Aleksandr Kokorinov (1769; St Petersburg, Rus. Mus.), which won Levitsky the title of Academician in 1770. In such works he made successful use of a compositional structure typical of formal European portrait painting, intended to emphasize the importance of the sitter.
Eastman Johnson
American portrait and genre painter, 1824-1906 American painter and printmaker. Between 1840 and 1842 he was apprenticed to the Boston lithographer John H. Bufford (1810-70). His mastery of this medium is apparent in his few lithographs, of which the best known is Marguerite (c. 1865-70; Worcester, MA, Amer. Antiqua. Soc.). In 1845 he moved to Washington, DC, where he drew portraits in chalk, crayon and charcoal of prominent Americans, including Daniel Webster, John Quincy Adams and Dolly Madison (all 1846; Cambridge, MA, Fogg). In 1846 he settled in Boston and brought his early portrait style to its fullest development. His chiaroscuro charcoal drawings, of exceptional sensitivity, were remarkably sophisticated for an essentially self-trained artist. In 1848 he travelled to Europe to study painting at the D?sseldorf Akademie. During his two-year stay he was closely associated with Emanuel Leutze, and painted his first genre subjects
Frederic Edwin Church
American Hudson River School Painter, 1826-1900 ..American painter. He was a leading representative of the second generation of the HUDSON RIVER SCHOOL, who made an important contribution to American landscape painting in the 1850s and 1860s. The son of a wealthy and prominent businessman, he studied briefly in Hartford with two local artists, Alexander Hamilton Emmons (1816-84) and Benjamin Hutchins Coe (1799-1883). Thanks to the influence of the Hartford patron DANIEL WADSWORTH, in 1844 he became the first pupil accepted by Thomas Cole. This was an unusual honour
