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 :. | Muscle structure of the thigh | Madonna with the Yarnwinder | Equestrian monument | Study fur the communion | Portrait of Ginevra de' Benci sg |

Jasper Francis Cropsey
(February 18, 1823 - April 23, 1900) was an important American landscape artist of the Hudson River School. Cropsey was born on his father Jacob Rezeau Cropsey's farm in Rossville on Staten Island, New York, the oldest of eight children. As a young boy, Cropsey had recurring periods of poor health. While absent from school, Cropsey taught himself to draw. His early drawings included architectural sketches and landscapes drawn on notepads and in the margins of his schoolbooks. Trained as an architect, he set up his own office in 1843. Cropsey studied watercolor and life drawing at the National Academy of Design under the instruction of Edward Maury and first exhibited there in 1844. A year later he was elected an associate member and turned exclusively to landscape painting; shortly after he was featured in an exhibition entitled "Italian Compositions." Cropsey married Maria Cooley in May 1847, traveled in Europe from 1847-1849, visiting England, France, Switzerland, and Italy. He was elected a full member of the Academy in 1851. Cropsey was a personal friend of Henry Tappan, the president of the University of Michigan from 1852 to 1863. At Tappan's invitation, he traveled to Ann Arbor in 1855 and produced two paintings, one of the Detroit Observatory, and a landscape of the campus. He went abroad again in 1855, and resided seven years in London, sending his pictures to the Royal Academy and to the International exhibition of 1862. Returning home, he opened a studio in New York and specialized in autumnal landscape paintings of the northeastern United States, often idealized and with vivid colors. Cropsey co-founded, with ten fellow artists, the American Society of Painters in Water Colors in 1866. He resided in the City until 1885, when he removed to Hastings-on-Hudson. The monument of Jasper Francis Cropsey in Sleepy Hollow CemeteryCropsey's home and studio, Ever Rest, in Hastings-on-Hudson, New York as well as the largest permanent collection of Cropsey's work are open for tours by the Newington-Cropsey Foundation. Jasper Cropsey died in anonymity but was rediscovered by galleries and collectors in the 1960s. Today, Cropsey's paintings are found in most major American museums, including the National Gallery of Art, the Metropolitan Museum of Art, the Los Angeles County Museum of Art, the Detroit Institute of Arts, the Timken Museum of Art in San Diego, the Honolulu Academy of Arts, the Fine Arts Museums of San Francisco, the Denver Art Museum, and the Museum of Fine Arts, Boston. Works by Cropsey also hang in the White House.
