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 :. | Madonna with the Yarnwinder | Madonna with the Yarnwinder ty | Annunciation | anna sjalv tredje | Maria with Child and St. Anna |

lesueur
Charles Alexandre Lesueur (Le Havre, January 1, 1778 - Le Havre, December 12, 1846) was a French naturalist, artist and explorer. Pictured here is the oil portrait by Charles Willson Peale of Charles-Alexandre Lesueur. The original hangs in the reading room of the of Ewell Sale Stewart Library in the Academy of Natural Sciences of Philadelphia. In 1801 he traveled to Australia as artist on the expedition of Nicolas Baudin. With François Peron he took over the duties as naturalist after the death of the expedition's zoologist Rene Mauge. Together they collected over 100,000 zoological specimens. Between 1815 and 1837 he lived in the United States In 1833, he visited Vincennes, Indiana where he sketched the first known drawing of Grouseland, the mansion of William Henry Harrison. The mansion is today a National Historic Landmark. In the years 1825-1837 Lesueur lived in New Harmony, Indiana, where he filled sketchbooks full of the finds discovered during the utopian adventure funded by his friend William Maclure. He drew the boat "Philanthropist", which arrived full of intellectuals who came to live in the small town of New Harmony, on the Wabash River. He took research trips and sketched the people and the small towns in the area. He was in New Harmony when Prince Maximilian, Prince of Wied-Neuweid, Germany, and artist Karl Bodmer came to spend five months there in 1832-1833. Prince Maximilian said of Bodmer "He had explored the country in many directions, was acquainted with everything remarkable, collected and prepared all interesting objects and had already sent considerable collections to France" (Elliott Johansen, p. 6) Indeed, LeSeur sent specimens of unique fish, animals and fossils, as well as artifacts he had dug from the Indian Mounds in New Harmony back to France, where they remain. LeSeur returned to France in 1837, only after his friends Thomas Say and Joseph Barabino had died and William MacClure had returned to Philadelphia, accompanied by many of his fine books. He had spent 21 years in the United States, but continued his scholarly studies and activities in France, where he resumed his occupation of artist-naturalist and began to catalogue his extensive research and artwork. At last, he was awarded the honor of Chevalier de l??Ordre Royal de la L??gion d'honneur for his long years of work in the sciences
Osborne, Walter
Irish, 1859-1903 Irish painter. The son of the animal painter William Osborne (1823-1901), he trained in the schools of the Royal Hibernian Academy (1876-81). In 1881 he won the Royal Dublin Society's Taylor scholarship and went to study at the Koninklijk Academie voor Schone Kunsten, Antwerp. Charles Verlat was the professor of painting, and Antwerp was then at the height of its popularity with students from the British Isles. In Antwerp and subsequently in Brittany, Osborne made contact with painters of the Newlyn school and other British naturalists. In Brittany he painted Apple Gathering, Quimperle (1883; Dublin, N.G.), a small greenish-grey picture of a girl in an orchard, which in subject and treatment shows the influence of Jules Bastien-Lepage. Throughout the 1880s Osborne worked in England, joining groups of artists in their search for the ideal naturalist motif. In the autumn of 1884 he was at North Littleton, near Evesham (Heref. & Worcs), where he painted Feeding Chickens in weather so cold that his model, a young peasant girl, nearly fainted. It is carefully drawn but painted with the square-brush technique characteristic of Bastien-Lepage's followers, and is very close to the contemporary work of George Clausen and Edward Stott (1855-1918). At Walberswick in Suffolk he painted October Morning (1885; London, Guildhall A.G.), a carefully studied plein-air work using bright dots of pure colour on a base of beige and grey. During this time Osborne gave careful attention to the showing of his work. He exhibited regularly at the Royal Hibernian Academy in Dublin from 1877 and at the Royal Academy in London from 1886.
