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 :. | Pod of cherry and forest strawberry | Study for a kneeling Leda | Bacchus | Leda | Flower Studies |

Frederick Edwin Church
1826-1900 Frederick Edwin Church Galleries Frederic Edwin Church (May 4, 1826 ?C April 7, 1900) was an American landscape painter born in Hartford, Connecticut. He was a central figure in the Hudson River School of American landscape painters. While committed to the natural sciences, he was "always concerned with including a spiritual dimension in his works". The family wealth came from Church's father, Joseph Church, a silversmith and watchmaker in Hartford, Connecticut.(Joseph subsequently also became an official and a director of The Aetna Life Insurance Company) Joseph, in turn, was the son of Samuel Church, who founded the first paper mill in Lee, Massachusetts in the Berkshires, and this allowed him(Frederic) to pursue his interest in art from a very early age. At eighteen years of age, Church became the pupil of Thomas Cole in Catskill, New York after Daniel Wadsworth, a family neighbor and founder of the Wadsworth Atheneum, introduced the two. In May 1848, Church was elected as the youngest Associate of the National Academy of Design and was promoted to Academician the following year. Soon after, he sold his first major work to Hartford's Wadsworth Atheneum. Church settled in New York where he taught his first pupil, William James Stillman. From the spring to autumn each year Church would travel, often by foot, sketching. He returned each winter to paint and to sell his work. Between 1853 and 1857, Church traveled in South America, financed by businessman Cyrus West Field, who wished to use Church's paintings to lure investors to his South American ventures. Church was inspired by the Prussian explorer Alexander von Humboldt's Cosmos and his exploration of the continent; Humboldt had challenged artists to portray the "physiognomy" of the Andes.

German, 1629-1698,Swedish nobleman and portrait painter who in 1652, at twenty-four years of age, at the request of Carl Gustaf Wrangel, moved to Skokloster Castle, from his art studies in the Netherlands. Between 1654 and 1661 he studied in Italy and visited the courts of both France and England. On his return he became entitled Court painter. He was raised to the nobility in 1674 and became court indendant in 1690. Mikael Dahl and David von Krafft as well as his daughter Anna Maria (born 1666) can be found among his pupils. The allegoric great hall ceiling fresco, named The Great Deeds of The Swedish Kings, in the Swedish House of Knights, made between 1670 and 1675, is considered to be his greatest work. A second version was made in Drottningholm Palace, the home of the Swedish Royal Family, in 1695. The Drottningholm fresco, also became the motive of the 1000th and ever largest postage stamp by Czeslaw Slania, the Polish
Donato Creti
(1671-1749) was an Italian painter of the Rococo period, active mostly in Bologna. Born in Cremona, he moved to Bologna, where he was a pupil of Lorenzo Pasinelli. He is described by Wittkower as the "Bolognese Marco Benefial", in that his style was less decorative and edged into a more formal neoclassical style. It is an academicized grand style, that crystallizes into a manneristic neoclassicism, with crisp and frigid modeling of the figures. Among his followers were Aureliano Milani, Francesco Monti, and Ercole Graziani the Younger. Two other pupils were Domenico Maria Fratta and Giuseppe Peroni
