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 :. | Plan fur a canal to the evasion of the Arno | Aurelio Luini attributed, profile of an old man | Studies of children | Anatomical studies of the basin of the Steibeins and the lower Gliedmaben of a woman and study of the rotation of the arms | Reverse side of the portrait of Ginevra de' Benci |

Samuel Palmer
1805-1881 British Samuel Palmer Galleries English painter, draughtsman and etcher. Palmer was a key figure of English Romantic painting who represented, at least in his early work, its pastoral, intuitive and nostalgic aspects at their most intense. He is widely described as a visionary and linked with his friend and mentor William Blake, though he stood at an almost opposite extreme in his commitment to landscape and his innocent approach to its imagery. He had none of Blake irony or complexity and was inspired by a passionate love of nature that found its philosophical dimension in unquestioning Neo-Platonism.
Jean-Baptiste Oudry
(17 March 1686 - 30 April 1755) was a French Rococo painter, engraver, and tapestry designer. He is particularly well known for his naturalistic pictures of animals and his hunt pieces depicting game. Jean-Baptiste Oudry was born in Paris, the son of Jacques Oudry, a painter and art dealer, and of his wife Nicole Papillon, who belonged to the family of the engraver Jean-Baptiste-Michel Papillon. His father was a director of the Academie de St-Luc art school, which Oudry joined. At first, Oudry concentrated on portraiture, and he became a pupil and perhaps a collaborator of Nicolas de Largilliere from 1707 to 1712. He graduated at only 22 years of age, on 21 May 1708, at the same time as his two older brothers. The next year, he married Marie-Marguerite Froisse,[1] the daughter of a miroitier (a mirror-maker) to whom he gave lessons in painting. Oudry became an assistant professor at Academie de Saint-Luc in 1714, and professor on 1 July 1717. He was inducted as a member of the prestigious Academie Royale de Peinture et de Sculpture in 1719, and was engaged as a professor there in 1743. After producing mainly portraits, Oudry started to produce still life paintings of fruits or animals, aa well as paintings of religious subjects, such as the Nativity, Saint Giles, and the Adoration of the Magi.
