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 :. | Mona lisa | Study for a kneeling Leda | Adoration of the Magi | The Virgin of the Rocks | Portrait of Ginerva de'Benci-u |

Bartholomeus Breenbergh
(before 13 November 1598 - after 3 October 1657) was a Dutch painter born in Deventer. Breenbergh established himself in Amsterdam and then in 1619 went to Rome. There he lived and worked with the Flemish painter Frans van de Kasteele and was heavily influenced by another Fleming, the landscape painter Paul Bril. From 1623, however, he came completely under the spell of Italian landscapes by the somewhat older Cornelis van Poelenburgheindeed, the works of Breenbergh and van Poelenburgh are sometimes very difficult of tell apart. Breenbergh in his turn influenced the French painter Claude Lorrain. Breenbergh was one of the founders of the Bentvueghels, where he was nicknamed "het fret". In 1633 Breenbergh returned to Amsterdam, where he remained until his death, and where he made paintings and etchings of Italian buildings. There he was influenced by the pre-Rembrandtists such as Pieter Lastman and Nicolaes Moeyaert, but he placed their Biblical and mythological scenes in Italian landscapes.
Poynter, Sir Edward John
English Classicist Painter, 1836-1919 English painter, draughtsman, decorative designer and museum official. He came from an artistic family: his great-grandfather was Thomas Banks the sculptor, and Ambrose Poynter, his father, was an architect and watercolour painter. Edward began studying art in 1852 under Thomas Shotter Boys, a friend of his father. In 1853-4 Poynter visited Rome, where he was greatly impressed by the large-scale academic painting of Frederic Leighton. Returning to London, he studied at Leigh's Academy and the studio of William Dobson (1817-1898). Poynter entered the Royal Academy Schools in 1855 but his admiration for French painting led him to Charles Gleyre's studio in Paris the following year. He remained there until 1859, with fellow students George Du Maurier, Thomas Armstrong and Whistler; their activities are described in Du Maurier's novel Trilby (1894). At this time Poynter received his first commissions for decorative work. He began designing stained glass and painting furniture and, after his return to England, he was employed by his friend the architect William Burges to decorate the ceiling of Waltham Abbey, Essex, in 1860.
Marsden Hartley
1877-1943 Marsden Hartley (January 4, 1877 - September 2, 1943) was an American Modernist painter and poet in the early 20th century. Hartley was born in Lewiston, Maine, USA. He began his art training at the Cleveland Institute of Art after moving to Cleveland, Ohio in 1892. At the age of 22, he moved to New York City, where he attended the National Academy of Design and studied painting at the Art Students League of New York under William Merritt Chase. A great admirer of Albert Pinkham Ryder, Hartley would visit Ryder's studio in Greenwich Village as often as possible. While in New York, he came to the attention of Alfred Stieglitz and became associated with Stieglitz' 291 Gallery Group. Hartley had his first major exhibition at the 291 Gallery in 1909 and another in 1912. He was in the cultural vanguard, in the same milieu as Gertrude Stein, Hart Crane, Charles Demuth, Georgia O'Keeffe, Fernand Leger, Ezra Pound, among many others. Hartley, who was gay, painted Portrait of a German Officer (1914), which was an ode to Karl von Freyburg, a Prussian lieutenant of whom he became enamored before von Freyburg's death in World War I.
