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 :. | The master of the Pala Sforzesca attributed | St John the Baptist t | Mona Lisa | The Refectory with the Last Supper after restoration g | anna sjalv tredje |

Arthur Quartley
(May 24, 1839 - May 19, 1886), was an American painter known for his marine seascapes. Quartley was born in Paris and lived there to the age of twelve, when his family moved to Baltimore, Maryland. He studied drawing with his father C.G. Quartley, who was an English engraver. His father was reputed to have demanded two drawings per week from the young lad. At age 17, Arthur was apprenticed to a sign painter in Baltimore. In 1862 Quartley and his family founded a design firm in Baltimore. The firm Emmart & Quartley was regarded as the best decorating company in the city (Dictionary of American Biography); however, young Quartley began painting marine seascapes of Chesapeake Bay, and progressively spent more and more time in that pursuit. He held a successful show of marine paintings at the studio of Norval H. Busey in Baltimore. Scholar Elizabeth Johns remarked that Quartley's work reveals familiarity with the Dutch Masters marine tradition of composition in treatment of light and color. To pursue his painting more seriously, Quartley moved to New York City in 1875. New York at that time had become a premier center for notable painters. From there he painted seascapes of Long Island bays, New York Harbor, the New Hampshire Isle of Shoals, and Naragansett Bay in Rhode Island. The Hudson River School was waning at this point, so that other groups were forming, among them the Tilers, of whom Quartley was a founding member. The Tilers was a group of artists and writers, that included such luminaries as Winslow Homer, William Merritt Chase, and Augustus Saint Gaudens. They met frequently to exchange ideas and decorate ceramic tiles in promotion of their works. They also took excursions for painting, such as the 1878 pilgrimage to Eastern Long Island by Quartley and ten others. On that trip Quartley painted Seascape and also a blue painted tile of an introspective girl at the beach. The journalist and philanthropist John W. McCoy promoted the careers of Quartley and of his friend, the sculptor William H. Rinehart.
