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 :. | Annunciation (detail) fg47 | Salai as John the Baptist | Virgin and Child with St Anne and St John the Baptist (mk08) | Leda h | Profile of an old man |

Arthur Pond
Arthur Pond (1705?-1758) was an English painter and engraver. Born about 1705, was educated in London, and stayed for a time in Rome studying art, in company with the sculptor Roubiliac. He became a successful portrait-painter. He was elected a Fellow of the Royal Society in 1752, and died in Great Queen Street, Lincoln's Inn Fields, 9 September 1758. His numerous original portraits include Alexander Pope, William, Duke of Cumberland, and Peg Woffington. Pond was also a prolific etcher, and used various mixed processes of engraving by means of which he imitated or reproduced the works of masters such as Rembrandt, Raphael, Salvator Rosa, Parmigiano, Caravaggio, and the Poussins. In 1734-5 he published a series of his plates under the title Imitations of the Italian Masters. He also collaborated with George Knapton in the publication of the Heads of Illustrious Persons, after Jacobus Houbraken and George Vertue, with lives by Thomas Birch (London, 1743-52); and engraved sixty-eight plates for a collection of ninety-five reproductions from drawings by famous masters, in which Knapton was again his colleague. Another of his productions was a series of twenty-five caricatures after Pier Leone Ghezzi, republished in 1823 and 1832 as Eccentric Characters.
Marmion, Simon
French-born Flemish Northern Renaissance Painter, ca.1425-1489 French illuminator and painter. He was trained in Amiens and established a productive workshop in Valenciennes, but at the end of his career appears to have had connections with manuscript painting in the southern Netherlands. Although no signed or documented works survive, many illuminated manuscripts and some panel paintings have been convincingly attributed to him and his workshop. On the basis of these he has been recognized as an important figure in the development of both French and Netherlandish painting.
Moran, Thomas
American Hudson River School Painter, 1837-1926 American painter and printmaker of English birth. His brothers Edward (1829-1901), John ( 1831-1902) and Peter (1841-1914) were also active as artists. His family emigrated from England and in 1844 settled in Philadelphia where Moran began his career as an illustrator. He was guided by his brother Edward, an associate of the marine painter James Hamilton, whose successful career afforded an example for Moran. Between the ages of 16 and 19 Moran was apprenticed to the Philadelphia wood-engraving firm Scattergood & Telfer; he then began to paint more seriously in watercolour and expanded his work as an illustrator. In the 1860s he produced lithographs of the landscapes around the Great Lakes. While in London in 1862 (the first of many trips to England), he was introduced to the work of J. M. W. Turner, which remained a vital influence on him throughout his career. Moran owned a set of the Liber studiorum and was particularly impressed by Turner's colour and sublime conception of landscape. With his wife, Mary Nimmo Moran (1842-99), an etcher and landscape painter, he participated in the Etching Revival, scraping fresh and romantic landscapes and reproductive etchings
