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 :. | Power and ortraits | Portrait of a Musician dey | Mona Lisa | Madonna with the Yarnwinder | Portrait |

James Seymour
British Painter , ca.1702-1752 English painter and draughtsman. The son of James Seymour (d 1739), a dealer in pictures and precious metals, Seymour was among the first English painters to specialize exclusively in sporting subject-matter. Though he possibly received some informal drawing instruction from the topographer Francis Place, Seymour was essentially a self-taught artist whose education was based on the study of pictures that passed through his father's hands; one of his earliest known works is a sketch of a horse's head after van Dyck (sold London, Christie's, 16 June 1970). His early 'genius to drawing of horses' was, according to George Vertue, compromised by 'modish extravagances' through living 'gay high and loosely' and because he 'never studied enough to paint or colour well'. Elsewhere, however, it was recorded that by 1739 he was 'reckoned the finest draughtsman in his way [of horses, hounds etc.] in the whole world' (Universal Spectator, 1739), and he was certainly preferred to his chief rival, John Wootton, by many sporting patrons. Among his employers was William Jolliffe MP, of Ammerdown. Though many of his paintings are either derivative of Wootton or simply inept, or both, others are characterized by a self-conscious stylistic naivety in which meticulous attention to detail and eerily static compositions combine to create curiously memorable images of some apparent sophistication.

Francis Gruber (1912-1948) was a French painter and founder of the Nouveau R??alisme school. Self-portrait 1942He was born in Nancy, the son of stained glass artist Jacques Gruber. He first exhibited at the age of 18. While other artists were becoming more and more abstract, he preferred to paint human figures that were highly sculpted. He was influenced by Hieronymus Bosch and Albrecht D??rer and the Lorraine engraver Jacques Callot. He became friends with the Swiss artist Alberto Giacometti.
Jan Porcellis
(1583/5 - 29 January 1632) was a Dutch marine artist. Porcellis was born in Ghent. He was the father of the marine artist Julius Porcellis (they shared a similar repertoire of subjects and an identical signature monogram), and is generally agreed to be the more fluent artist, particularly in his sense of space and his tonal palette (subtler than his son's). He died at Zoeterwoude.
