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 :. | Reverse side of the portrait of Ginevra de' Benci | Adoration of the Magi | Portrait of Ginevra de' Benci | The Virgin and Child with Anne (mk05) | The Virgin of the Rocks |

George Durrie
Landscape painter, Portrait Painter . American , 1820-1863 American painter. Durrie and his older brother John (1818-98) studied sporadically from 1839 to 1841 with the portrait painter Nathaniel Jocelyn. From 1840 to 1842 he was an itinerant painter in Connecticut and New Jersey, finally settling permanently in New Haven. He produced c. 300 paintings, of which the earliest were portraits (e.g. Self-portrait, 1839; Shelburne, VT, Mus.); by the early 1850s he had begun to paint the rural genre scenes and winter landscapes of New England that are considered his finest achievement. His landscapes, for example A Christmas Party (1852; Tulsa, OK, Gilcrease Inst. Amer. Hist. & A.), are characterized by the use of pale though cheerful colours and by the repeated use of certain motifs: an isolated farmhouse, a road placed diagonally leading the eye into the composition, and a hill in the distance. By the late 1850s Durrie's reputation had started to grow, and he was exhibiting at prestigious institutions, such as the National Academy of Design. In 1861 the firm of Currier & Ives helped popularize his work by publishing prints of two of his winter landscapes, New England Winter Scene and the Farmyard in Winter.
