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 :. | Leda | The last dinner | Muscles and bone of leg and Hufte | Anatomical studies of the basin of the Steibeins and the lower Gliedmaben of a woman and study of the rotation of the arms | Study fur a women head |

Samuel Howitt
English, 1756-1822,was an artist from England. Samuel Howitt was born into a wealthy Quaker family in Nottinghamshire, England. He began painting as a hobby and to amuse his friends. Hunting and racing were his hobbies and he mimicked this interest in his work. Howitt's family experienced financial difficulties, so Howitt decided to move to London. In London, Howitt made a career out of his talent, flourishing as a professional artist. He was published often in The Sporting Magazine and went on to illustrate various books. Howitt is best known for his lively and exotic sporting scenes. His superior watercolors and aquatints depict dramatic racing and hunting scenes as well as an array of conventional and exotic animals. Howitt's work is included in the Mellon Collection, which possesses no fewer than 160 of his watercolors, and many of his aquatints. Howitt exhibited at the Royal Academy and illustrated several books, including his own entitled The British Sportsman c.1812 and British Preserve c.1824. Samuel Howitt, "genius, artist, sportsman", concentrated his considerable artistic talents on picturing scenes of horse-racing and hunting in all its aspects. Born in Nottinghamshire, England, Howitt was largely self-taught ,"although he must have been helped by his companions George Morland, Rowlandson and John Raphael Smith. Howitt's watercolours of hunting, shooting and racing have delightful spontaneity.
Joris van der Haagen
(ca. 1615 - The Hague, 23 May 1669 (buried)) was a Dutch Golden Age painter specialized in landscapes. Contents It is unclear where Joris van der Haagen was born, either in Arnhem or Dordrecht, but archival evidence shows that he started his drawing career in Arnhem. He probably learned to paint from his father, the painter Abraham van der Haagen. When his father died he moved in 1639 to the Hague, where he joined the Guild of St. Luke in 1643. A year later he became honorary citizen of The Hague. In 1656 he was one of the founding members of the Confrerie Pictura, which was located on the Princessegracht in the Hague. The painting he made of the Princessegracht at this time probably shows the original building, which has since been renovated beyond recognition.
roger de la fresnaye
Roger de La Fresnaye (11 July 1885 - 27 November 1925) was a French cubist painter. He was born in Le Mans where his father, an officer in the French army, was temporarily stationed. The La Fresnaye's were an aristocratic family whose ancestral home, the Château de La Fresnaye, is in Falaise. His education was classically based, and was followed from 1903 to 1904 by studies at the Acad??mie Julian in Paris, and from 1904 to 1908 at the Ecole des Beaux-Arts. From 1908 he studied at the Acad??mie Ranson under Maurice Denis and Paul S??rusier, whose joint influence is evident in early works such as Woman with Chrysanthemums, 1909. This demonstrates the dreamlike symbolist ambience and stylistic character of work by the Les Nabis group. The Conquest of the Air, 1913. Museum of Modern Art, New York.From 1912 to 1914 he was a member of the Section d'Or group of artists, and his work demonstrates an individual response to cubism. He was influenced by Georges Braque and Pablo Picasso , but his work has a more decorative than structural feel and his prismatic colours reflect the influence of Robert Delaunay. He was a member of the Puteaux Group, an orphist offshoot of cubism led by Jacques Villon. His most famous work is The Conquest of the Air, 1913, and depicts a scene with himself and his brother outdoors with a balloon in the background. La Fresnaye served in the French army in World War I and his health deteriorated rapidly after the war. He never recovered the physical energy to undertake sustained work. In the later paintings that he did create, he abandoned cubist spatial analysis for a more linear style. He died in Grasse in 1925.
