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 :. | Virgin of th Rock (mk08) | Portrait | Madonna in the rock grotto | Studies fur the adoration of the Konige | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici |

Thomas Eakins
American Realist Painter, 1844-1916. Thomas Cowperthwait Eakins (July 25, 1844 ?C June 25, 1916) was a realist painter, photographer, sculptor, and fine arts educator. He is widely acknowledged to be one of the most important artists in American art history. For the length of his professional career, from the early 1870s until his health began to fail some forty years later, Eakins worked exactingly from life, choosing as his subject the people of his hometown of Philadelphia. He painted several hundred portraits, usually of friends, family members, or prominent people in the arts, sciences, medicine, and clergy. Taken en masse, the portraits offer an overview of the intellectual life of Philadelphia in the late 19th and early 20th centuries; individually, they are incisive depictions of thinking persons. As well, Eakins produced a number of large paintings which brought the portrait out of the drawing room and into the offices, streets, parks, rivers, arenas, and surgical amphitheaters of his city. These active outdoor venues allowed him to paint the subject which most inspired him: the nude or lightly clad figure in motion. In the process he could model the forms of the body in full sunlight, and create images of deep space utilizing his studies in perspective. No less important in Eakins' life was his work as a teacher. As an instructor he was a highly influential presence in American art. The difficulties which beset him as an artist seeking to paint the portrait and figure realistically were paralleled and even amplified in his career as an educator, where behavioral and sexual scandals truncated his success and damaged his reputation. Eakins also took a keen interest in the new technologies of motion photography, a field in which he is now seen as an innovator. Eakins was a controversial figure whose work received little by way of official recognition during his lifetime. Since his death, he has been celebrated by American art historians as "the strongest, most profound realist in nineteenth-and early-twentieth-century American art".
