Leonardo Da Vinci
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 Artists:Sven Birger Sandzen
(5 February 1871-19 June 1954), known more commonly as Birger Sandzen, was a Swedish-American painter best known for his landscapes. He produced most of his work while working as an art professor at the Bethany College, Lindsborg, Kansas.
Sandzen was born in Blidsberg, Ulricehamn Municipality, Västra Götaland County, Sweden, the son of a Lutheran minister and his wife, an accomplished watercolorist. A protege of Anders Zorn, Sandzen showed an interest in art at from early age, and at the age of 10 joined Cathedral School (Katedralskolan) situated in Skara, to study art under the tutelage of Olof Erlandsson, a graduate of the Royal Swedish Academy of Arts. After graduating in 1890, Sandzen studied for a short time at the University of Lund before moving to Stockholm. It was his intention to enroll at the Royal Swedish Academy of Arts. However, the waiting list proved too long for him. Instead, he sought out and joined a group of young artists who were studying under Anders Zorn, Richard Bergh and Per Hasselberg. This group would later be known as the Artists League (Konstnärsförbundet).At the end of his studies, Zorn and Bergh recommended that Sandzen complete his painting studies in Paris. In 1894, Sandzen left Stockholm to study under Edmond Aman-Jean who introduced Sandzen to pointillism. Amico Aspertini
(c. 1474 - 1552) is an Italian Renaissance painter whose complex, eccentric, and eclectic style anticipates Mannerism. He is considered among the first of the Bolognese School of painting.
He was born in Bologna to a family of painters (Guido Aspertini and Giovanni Antonio Aspertini, his father), and studied under masters such as Lorenzo Costa and Francesco Francia. He is briefly documented in Rome between 1500 - 1503, returning to Bologna and painting in a style influenced by Pinturicchio. In Bologna in 1504, he joined Francia and Costa in painting frescoes for the newly restored Oratory of Santa Cecilia in San Giacomo Maggiore, a work commissioned by Giovanni II Bentivoglio.
In 1507-09, he painted a fresco cycle in San Frediano in Lucca. Asperini painted in 1508-1509 the splendid frescoes in the Chapel of the Cross in the Basilica di San Frediano in Lucca. Aspertini was also one of two artists chosen to decorate a triumphal arch for the entry into Bologna of Pope Clement VII and Emperor Charles V in 1529.
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.
