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 :. | Salai as John the Baptist | virgin and child with st.anne | Mona Lisa | Last Supper | The Virgin and St Anne |

Levi Wells Prentice
1850-1935 Levi Wells Prentice Gallery Prentice was associated with the Hudson River School, a group of artists known throughout art circles. According to the book Nature Staged by Barbara Jones, Prentice followed a self-prescribed educational path, begun by the Hudson River School and reinforced by John Ruskin's (1819-1900) truth-to-nature principles laid out in his book Modern Painters. Although he can be allied to both schools of thought, Prentice can not be considered a member of either. This book has a photo of the artist in his early Brooklyn studio surrounded by his paintings and a complete essay on his life and work. Levi grew up on a farm in Lewis County, New York. By 1872, Prentice had traveled through the Adirondack Mountains, painting the views as well as the surrounding region. He opened his first studio as a landscape painter in Syracuse, New York in 1875. Self-taught artist Levi Wells Prentice is best known for his realistic still life compositions of fruit arranged within a landscape, or abundantly spilling from bushel baskets. Early in his career, he painted portraits and landscapes of the Adirondack Mountain region of Lewis County, New York, his birthplace. Levi married an English woman Emma Roseloe Sparks in Buffalo, New York in 1882 and had two children, Leigh (born 22 March 1887) and Imogene (born 17 September 1889). Prentice then turned to painting still life subjects when he moved briefly to Brooklyn, New York in 1883, focusing on fruit, in order of frequency apples, strawberries, peaches, plums, raspberries, cherries, muskmelons, pears, currants, pineapples, gooseberries, grapes and bananas usually piled high in pots or in natural settings. Prentice subsequently moved around from 1903-07 before settling in the Germantown district of Philadelphia. However, his work did not gain much recognition with historians until the 1970s. He was a member of the Brooklyn Art Association and frequently exhibited his paintings there. In addition to his artistic talents, he was a craftsman who enjoyed making his own brushes, palettes and frames. In his painting, Prentice placed an emphasis on dark outlining with a concern for textual precision, creating dramatic contrasts. The shift between dark background areas and the vibrant hues of the fruit are done to give the compositions an exciting, visual energy. The fruit is presented with clarity and precision. An emphasis appears to be placed on the idea of man versus nature. The wooden baskets with hand-wrought nails represent a structured, man-made object, while the overly ripe fruit represents the fleeting qualities of nature. These paintings also demonstrate Prentice's remarkable skills at rendering color, form, and texture. Noted art historian William H. Gerdts observed: there are several works by Prentice in which he achieves a quality of illusionism which is unsurpassed. In 1993, the skillful 'illusionism' of Levi Wells Prentice was celebrated in a retrospective exhibition at the Adirondack Museum in New York. His works continue to receive a high degree of appreciation by collectors today. He is represented in many museums including the New York State Museum, Museum of Fine Arts, Boston, Montclair Art Museum, Philbrook Museum of Art and Yale University Art Gallery. Levi died 28 November 1935 in Germantown, Pennsylvania.
