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 :. | Profile of an old man | Saint jean-Baptiste | The Annunciation | Madonna with the carnation | Cecila Gallerani (mk45) |

Galland Pierre Victor
Geneve 1822-Paris 1892 He studied metalwork with his father Jacques Galland, an accomplished goldsmith, until age 16. He then entered the studio of Henri Labrouste to study architecture. After two years of training, Labrouste encouraged him to pursue his interest in decorative painting under the direction of Michel-Martin Drolling. In 1843 the decorative painter Pierre-Luc-Charles Ciceri (1782-1868) hired Galland to assist with the painting of figures, flowers, garlands and fruit. He worked again with Labrouste, in 1848, on the decoration of the national festival, the F?te de la Concorde.
Polk, Charles Peale
American, 1767-1822 American painter. Orphaned as a child, he was raised in Philadelphia, PA, by his uncle, Charles Willson Peale, who taught him to paint. In 1791 Polk moved to Baltimore, MD, where he achieved limited success as a portrait painter. Seeking commissions, he moved to Frederick, MD, in 1796. Over the next five years during travels as an itinerant limner through western Maryland and Virginia he reached his mature style. Abandoning his academic training, Polk developed a distinctive but naive artistic vocabulary with a heightened palette, electric highlights and an exaggerated attenuation of the human form. The portraits of Isaac Hite and his wife Eleanor Madison Hite, as well as James Madison sr and Eleanor Conway Madison (all Middletown, VA, Belle Grove), were commissioned in 1799 and are accepted as his masterpieces. Isaac Hite also commissioned the quintessentially 'republican' portrait of Thomas Jefferson (New York, Victor Spark priv. col.), executed at Monticello in 1799. In 1801 Polk moved to Washington, DC, working as a clerk in the Treasury. During the next 16 years he painted few portraits in oil
Samuel Prout
English Painter, 1783-1852 was an English water-colour painter. He was born at Plymouth, and spent whole summer days, in company with Benjamin Haydon, drawing the quiet cottages, rustic bridges and romantic watermills of the beautiful valleys of Devon. He made a journey through Cornwall to try his hand in furnishing sketches for Britton's Beauties of England. In 1803 he moved to London, where he stayed until 1812. In London, Prout saw new possibilities, and endeavoured to correct and improve his style by studying the works of the rising school of landscape. To earn a living, he painted marine pieces for Palser the printseller, took students, and published drawing books for learners. He was one of the first to use lithography in his artwork. It was not however until about 1818 that Prout discovered his niche. Happening time to make his first visit to the Continent, and to study the quaint streets and market-places of continental cities, he suddenly found himself in a new and enchanting province of art. His eye caught the picturesque features of the architecture, and his hand recorded them with skill. The composition of his drawings was exquisitely natural; their colour exhibited "the truest and happiest association in sun and shade"; the picturesque remnants of ancient architecture were rendered with the happiest breadth and largeness, with the heartiest perception and enjoyment of their time-worn ruggedness
