LEONARDO da Vinci

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 | Virgin of the Rocks | Madonna with a Flower (Madonna Benois) g | The Portinari Altarpiece | Madonna in the cave |

Henry Thomas Alken
1785-1851, Painter and engraver, son of Samuel Alken. He worked in London and the provinces and was prolific in a variety of media while unadventurous in his range of subject-matter. Early instruction by the miniature painter J. T. Beaumont (1774-1851) helped to give a certain graphic precision
Percy Gray
1869-1952 was an American painter. Gray was born into a San Francisco family endowed with a broad literary and artistic background. He studied under Arthur Frank Mathews at the San Francisco School of Design and later under William Merritt Chase. While he had some early Impressionistic tendencies, his primary expression was under the Tonalism Mathews had brought back from Paris. He is known for his extraction of beauty from the Northern California landscape. Alexander Gray, Percy's father, was born in England, but found his way to a successful insurance business in San Francisco. As the byproduct of a childhood illness, Percy realized he had talents in art. From 1886 to 1888 he attended the California School of Design, then led by Mathews. From there he went on to become a newspaper illustrator, obtaining a job with the New York Journal. In New York he also studied at the Art Students League. He was dispatched from New York to cover the 1906 San Francisco earthquake, but decided to remain in his native city where he would then take up his painting career. Gray's first pieces, headland seascapes, were exhibited in 1907; soon thereafter he addressed in watercolor eucalyptus groves and fields of California wildflowers. These subjects would become signatures of his work. Originally Gray's works were oils; however, he eventually developed an allergy to oil paints, and therefore switched to using watercolors as his primary medium. [1] From early on the critics marvelled at his ability to infuse realistic depictions of nature with a mystical and poetic quality. He was clearly applying the precepts of his mentor William Merritt Chase in exaggeration of light and color. From 1912 to 1923 Gray lived in Burlingame, California about twenty miles south of San Francisco, while keeping his studio in the city itself. At the 1915 Panama-Pacific International Exposition he won a bronze medal for his watercolor Out of the Desert, Oregon. Having been a bachelor for 53 years, Gray surprised his friends by marrying. He and his bride moved to the Bonificio Adobe in Monterey, where seascapes and cypress dominated his later works.
