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 :. | Anatomy of the Schadels | A full-scale composition of the Virgin and Child with St Anne and the infant St John the Baptist | Our Lady and St Anne | Portrait of Ginevra de Benci | Madonna with the Yarnwinder |

Leslie Ward
British Illustrator caricaturist and portrait painter , (1851-1922), was a British portrait artist and caricaturist who drew or painted numerous portraits which were regularly published by Vanity Fair, under the pseudonym "Spy". Ward was one of eight children of artists Edward Matthew Ward and Henrietta Ward, and the great-grandson of the artist James Ward. Although they had the same surname before marriage, Ward's parents were not related. Both were well-known history painters, his mother coming from a line of painters and engravers, including her father, the engraver and miniature painter George Raphael Ward, and her grandfather, the celebrated animal painter James Ward. She was niece and great-niece respectively of the portrait painter John Jackson and the painter George Morland. Both parents had studios in their homes in Slough in Buckinghamshire and Kensington in London, where they regularly entertained the London artistic and literary elite. Ward's father was a gifted mimic who entertained Charles Dickens and other eminent guests. Although they never gave their son formal training, they and their artistic friends encouraged the young Ward to draw, paint, and sculpt.[1] Ward had started caricaturing while still at school at Eton in Windsor, using his classmates and school masters as subjects. In 1867 his bust of his brother was exhibited at the Royal Academy in London. At school Ward had been an unexceptional student, and after he left Eton in 1869 his father encouraged him to train as an architect. Ward was too afraid to tell his father that he wanted to be an artist and he spent an unhappy year in the office of the architect Sydney Smirke, who was a family friend.
Moritz Kellerhoven
(1758-1830), sometimes referenced as Moritz Keller Hoven, was an Austrian painter and etcher. Kellerhoven was born in Duchy of Berg, and spent some time studying art in Antwerp, Vienna, and Italy. He specialized in painting portraits, including many royal subjects. Kellerhoven died in Munich in 1830.
Pierre-Henri de Valenciennes
(December 6, 1750 - February 16, 1819) was a French painter. Valenciennes worked in Rome from 1778 to 1782, where he made a number of landscape studies directly from nature, sometimes painting the same set of trees or house at different times of day.He theorized on this idea in Advice to a Student on Painting, Particularly on Landscape (1800), developing a concept of a "landscape portrait" in which the artist paints a landscape directly while looking upon it, taking care to capture its particular details.Although he spoke of this as a type of painting mainly of interest to "amateurs", as distinguished from the higher art of the academies, he found it of great interest, and of his own works the surviving landscape portraits have been the most noted by later commentators. He in particular urged artists to capture the distinctive details of a scene's architecture, dress, agriculture, and so on, in order to give the landscape a sense of belonging to a specific place; in this he probably influenced other French artists active in Italy who took an anthropological approach to painting rural areas and customs, such as Hubert Robert, Pierre-Athanase Chauvin and Achille-Etna Michallon.
