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 :. | Head and shoulders Christs | Female head (La Scapigliata) wt | Annunciation (detail) dg | The Virgin and St Anne | Our Lady and St Anne |

Frantisek Kupka
Czech Abstract Painter, 1871-1957,was a Czech painter and graphic artist. He was a pioneer and co-founder of the early phases of the abstract art movement and orphic cubism (orphism). Kupka's abstract works arose from a base of realism, but later evolved into pure abstract art. Frantisek Kupka was born in Opocno, eastern Bohemia (now Czech Republic). From 1889 to 1892, he studied at the Prague Art Academy. At this time, he painted historical and patriotic themes. In Kupka enrolled at the Akademie der Bildenden Kunste in Vienna, Vienna, where he concentrated on symbolic and allegorical subjects. He exhibited at the Kunstverein, Vienna, in 1894. His involvement with theosophy and Eastern philosophy dates from this period. By spring 1894, Kupka had settled in Paris; there he attended the Academie Julian briefly and then studied with Jean-Pierre Laurens at the Ecole des Beaux-Arts. Kupka worked as an illustrator of books and posters and, during his early years in Paris, became known for his satirical drawings for newspapers and magazines. In 1906, he settled in Puteaux, a suburb of Paris, and that same year exhibited for the first time at the Salon d'Automne. Kupka was deeply impressed by the first Futurist Manifesto, published in 1909 in Le Figaro. Kupka's 1909 painting "Piano Keyboard/Lake" marked a break in his representational style; his work became increasingly abstract around 1910 C11, reflecting his theories of motion, color, and the relationship between music and painting (orphism). In 1911, he attended meetings of the Puteaux group. In 1912, he exhibited at the Salon des Independants in the Cubist room, although he did not wish to be identified with any movement. Creation in the Plastic Arts, a book Kupka completed in 1913, was published in Prague in 1923. In 1931, he was a founding member of Abstraction-Creation. In 1936, his work was included in the exhibition "Cubism and Abstract Art" at the Museum of Modern Art in New York, and in an important show with another excellent Czech painter Alphonse Mucha at the Jeu de Paume in Paris. A retrospective of his work took place at the Galerie Manes in Prague in 1946. The same year, Kupka participated in the Salon des Realites Nouvelles, where he continued to exhibit regularly until his death. During the early 1950s, he gained general recognition and had several solo shows in New York. Between 1919 and 1938 Kupka was financially supported by his good friend, art collector and industrialist Jindich Waldes who accumulated a substantial collection of his art. Kupka died in Puteaux, France. Kupka had a strong interest in color theory; around 1910 he began developing his own color wheels, adapting a format previously explored by Sir Isaac Newton and Hermann von Helmholtz. This work in turn led Kupka to execute a series of paintings he called "Discs of Newton" (1911-12).
