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 :. | The master of the Pala Sforzesca attributed | Reverse side of the portrait of Ginevra de' Benci sg | Leda fh | Benois Madonna | Equestrian monument |

John Frederick Peto
1854-1907 John Frederick Peto Gallery John Frederick Peto (May 21, 1854 ?C November 23, 1907) was an American trompe l'oeil ("fool the eye") painter who was long forgotten until his paintings were rediscovered along with those of fellow trompe l'oeil artist William Harnett. Although Peto and the slightly older Harnett knew each other and painted similar subjects, their careers followed different paths. Peto was born in Philadelphia, Pennsylvania, and studied at the Pennsylvania Academy of the Fine Arts at the same time as Harnett.[1] Until he was in his mid-thirties, he submitted paintings regularly to the annual exhibitions at the Philadelphia Academy. In 1889, he moved to the resort town of Island Heights, New Jersey, where he worked in obscurity for the rest of his life. He and his wife took in seasonal boarders, he found work playing cornet at the town's camp revival meetings, and he supplemented his income by selling his paintings to tourists.[2] He never had a gallery exhibition in his lifetime.[3] Harnett, on the other hand, achieved success and had considerable influence on other artists painting in the trompe l'oeil genre, but even his paintings were given the snub by critics as mere novelty and trickery. Both artists were masters of trompe l'oeil, a genre of still life that aims to deceive the viewer into mistaking painted objects for reality. Exploiting the fallibility of human perception, the trompe l'oeil painter depicts objects in accordance with a set of rules unique to the genre. For example, Peto and Harnett both represented the objects in their paintings at their actual size, and the objects rarely were cut off by the edge of the painting, as this would allow a visual cue to the viewer that the depiction was not real. But the main technical device was to arrange the subject matter in a shallow space, using the shadow of the objects to suggest depth without the eye seeing actual depth. Thus the term trompe l'oeil??"fool the eye." Both artists enthrall the viewer with a disturbing but pleasant sense of confusion. Letter Rack by PetoPeto's paintings, generally considered less technically skilled than Harnett's,[4] are more abstract, use more unusual color, and often have a stronger emotional resonance. Peto's mature works have an opaque and powdery texture which is often compared to Chardin.[5] The subject matter of Peto's paintings consisted of the most ordinary of things: pistols, horseshoes, bits of paper, keys, books, and the like. He frequently painted old time "letter racks," which were a kind of board that used ribbons tacked into a square that held notes, letters, pencils, and photographs. Many of Peto's paintings reinterpret themes Harnett had painted earlier,[6] but Peto's compositions are less formal and his objects are typically rustier, more worn, less expensive looking.[7] Other artists who practiced trompe l'oeil in the late nineteenth century include John Haberle and Jefferson David Chalfant. Otis Kaye followed several decades later. A pioneering study of Peto and Harnett is Alfred Frankenstein's After the Hunt, William Harnett and Other American Still Life Painters 1870-1900. Frankenstein's book itself is a fantastic tale of solving the mystery of why these artists were forgotten for much of the twentieth century.
