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 :. | Mona Lisa | The muscles of arm, shoulder and neck | Madonna and Child with St Anne and the Young St John | Profiles of a young and an old man | Portrait of a Musician dey |

George Catlin
1796-1872 George Catlin Galleries Catlin was born in Wilkes-Barre, Pennsylvania. Following a brief career as a lawyer, he produced two major collections of paintings of American Indians and published a series of books chronicling his travels among the native peoples of North, Central and South America. Claiming his interest in America??s 'vanishing race' was sparked by a visiting American Indian delegation in Philadelphia, he set out to record the appearance and customs of America??s native people. Catlin began his journey in 1830 when he accompanied General William Clark on a diplomatic mission up the Mississippi River into Native American territory. St. Louis became Catlin??s base of operations for five trips he took between 1830 and 1836, eventually visiting fifty tribes. Two years later he ascended the Missouri River over 3000 km to Ft Union, where he spent several weeks among indigenous people still relatively untouched by European civilization. He visited eighteen tribes, including the Pawnee, Omaha, and Ponca in the south and the Mandan, Cheyenne, Crow, Assiniboine, and Blackfeet to the north. There, at the edge of the frontier, he produced the most vivid and penetrating portraits of his career. Later trips along the Arkansas, Red and Mississippi rivers as well as visits to Florida and the Great Lakes resulted in over 500 paintings and a substantial collection of artifacts. When Catlin returned east in 1838, he assembled these paintings and numerous artifacts into his Indian Gallery and began delivering public lectures which drew on his personal recollections of life among the American Indians. Catlin traveled with his Indian Gallery to major cities such as Pittsburgh, Cincinnati, and New York. He hung his paintings ??salon style????side by side and one above another??to great effect. Visitors identified each painting by the number on the frame as listed in Catlin??s catalogue. Soon afterwards he began a lifelong effort to sell his collection to the U.S. government. The touring Indian Gallery did not attract the paying public Catlin needed to stay financially sound, and Congress rejected his initial petition to purchase the works, so in 1839 Catlin took his collection across the Atlantic for a tour of European capitals. Catlin the showman and entrepreneur initially attracted crowds to his Indian Gallery in London, Brussels, and Paris. The French critic Charles Baudelaire remarked on Catlin??s paintings, ??M. Catlin has captured the proud, free character and noble expression of these splendid fellows in a masterly way.?? Catlin??s dream was to sell his Indian Gallery to the U.S. government so that his life??s work would be preserved intact. His continued attempts to persuade various officials in Washington, D.C. failed. He was forced to sell the original Indian Gallery, now 607 paintings, due to personal debts in 1852. Industrialist Joseph Harrison took possession of the paintings and artifacts, which he stored in a factory in Philadelphia, as security. Catlin spent the last 20 years of his life trying to re-create his collection. This second collection of paintings is known as the "Cartoon Collection" since the works are based on the outlines he drew of the works from the 1830s. In 1841 Catlin published Manners, Customs, and Condition of the North American Indians, in two volumes, with about 300 engravings. Three years later he published 25 plates, entitled Catlin??s North American Indian Portfolio, and, in 1848, Eight Years?? Travels and Residence in Europe. From 1852 to 1857 he traveled through South and Central America and later returned for further exploration in the Far West. The record of these later years is contained in Last Rambles amongst the Indians of the Rocky Mountains and the Andes (1868) and My Life among the Indians (ed. by N. G. Humphreys, 1909). In 1872, Catlin traveled to Washington, D.C. at the invitation of Joseph Henry, the first secretary of the Smithsonian. Until his death later that year in Jersey City, New Jersey, Catlin worked in a studio in the Smithsonian ??Castle.?? Harrison??s widow donated the original Indian Gallery??more than 500 works??to the Smithsonian in 1879. The nearly complete surviving set of Catlin??s first Indian Gallery painted in the 1830s is now part of the Smithsonian American Art Museum's collection. Some 700 sketches are in the American Museum of Natural History, New York City. The accuracy of some of Catlin's observations has been questioned. He claimed to be the first white man to see the Minnesota pipestone quarries, and pipestone was named catlinite. Catlin exaggerated various features of the site, and his boastful account of his visit aroused his critics, who disputed his claim of being the first white man to investigate the quarry. Previous recorded white visitors include the Groselliers and Radisson, Father Louis Hennepin, Baron LaHonton and others. Lewis and Clark noted the pipestone quarry in their journals in 1805. Fur trader Philander Prescott had written another account of the area in 1831.
