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 :. | Annunciation | Studies of children | Lady with the ermine | Madonna and Child with St Anne and the Young St John | Abendmahl |

Stettheimer Florine
American Painter, 1871-1944 was an American artist. She has been described as "a Deco-influenced early Modernist who??s never really gotten her due". Stettheimer was born in Rochester, New York to a wealthy family. She spent much of her early life traveling, studying art in Italy, Spain, France, Germany, and Switzerland. She studied for three years in the mid-1890s at the Art Students League in New York, but came into her own artistically upon her permanent return to New York after the start of World War I. In October 1916, the only one-person exhibition of her work during her lifetime took place at New York's Knoedler & Company. She exhibited 12 "high-keyed, decorative paintings", none of which were sold. Cushioned by family resources, Stettheimer refrained from self-promotion and considered her painting "an entirely private pursuit". She intended to have her works destroyed after her death, a wish defied by her sister Henrietta, her executor. Stettheimer's privileged position pervades her work. As one critic has written, "money she regarded as a birthright, decidedly not something to be flaunted in the shape of a dozen yachts, but rather to be used as a palliative against the more unpleasant aspects of the world outside
Johann Jakob Ulrich
impression atist 28 Feb 1798 -- 17 March 1877. Swiss painter. He first studied under his father and then in Paris in 1822 in the studio of Jean-Victor Bertin. As a student he concentrated on unusual lighting effects in his landscape paintings well before they became a hallmark of the precursors of the Impressionists. In 1824 at the Salon in Paris he first saw paintings by Constable. On a trip to Italy in 1828 he did studies en plein air as preliminary sketches for his studio paintings. His early paintings emphasize brilliant colour, low horizons and scientific observation of cloud formations in a manner similar to Constable's studies, which he actually saw on visits to England in 1832 and 1835. Like Eugene Boudin, Ulrich was interested in poetic evocations of sun, water and effects of atmosphere rather than in the precise delineations of topography typical of Swiss art of that period. From 1824 he showed regularly at the Salons in Paris and in 1837 he returned to Zurich. Because the Swiss public was reluctant to accept his freer,
