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 :. | Reverse side of the portrait of Ginevra de' Benci | The Battle of Anghiari | Bacchus (mk05) | Mona Lisa | Study of a child |

John Haberle
(1856-1933) was a 19th-century American painter in the trompe l'oeil (literally, "fool the eye") style. His still lifes of ordinary objects are painted in such a way that the painting can be mistaken for the objects themselves. He is considered one of the three major figuresetogether with William Harnett and John F. Petoepracticing this form of still life painting in the United States in the last quarter of the 19th century. Haberle was born in New Haven, Connecticut; his parents were Swiss immigrants. At the age of 14 he left school to apprentice with an engraver. He also worked for many years as an exhibit preparator for the Peabody Museum of Natural History at Yale University. His career as a painter began in 1887. His style is characterized by a meticulous rendering of two-dimensional objects. He is especially noted for his depictions of paper objects, including currency. Art historian Alfred Frankenstein has contrasted Haberle's work with that of his contemporaries: Peto is moved by the pathos of used-up things. Haberle is wry and wacky, full of bravado, self-congratulating virtuosity, and sly flamboyance. He works largely within an old tradition, that of the trompe l'oeil still life in painted line ... It is poles away from Harnett's sumptuosity, careful balances, and well-modeled volumes, and is equally far from Peto's sensitivity in matters of tone and hue. A Bachelor's Drawer (1890-94) is typical of his approach: various papers, including currency, postage stamps, photos, playing cards, tickets, and newspaper clippings, are shown affixed to an essentially planar surface. Other objectseeyeglasses, a comb, a pipe, matches, and so oneare shallow enough in volume so as not to spoil the illusion. Like Harnett, he was warned by the Secret Service to cease and desist painting paper money, but he continued to do so throughout his years of greatest productivity; examples include The Changes of Time (1888) and Can You Break a Five? (c. 1885). He painted other subjects such as Slate (c. 1895), a bin of peanuts in Fresh Roasted (1887), The Clay Pipe (1889), and the huge Grandma's Hearthstone (1890), in the collection of the Detroit Institute of Arts. By the turn of the century, problems with his eyes diminished Haberle's activity as an artist. Among his later works are paintings of flowers executed in a looser style, and in 1909 he painted his final trompe l'oeil, the large Night, in the collection of the New Britain Museum of American Art, New Britain, Connecticut. Haberle died in 1933.
