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 :. | Portrait of Ginevra de' Benci | Madonna with a Flower | Bacchus | Flower Studies | The Annunciation |

John George Brown
1831-1913 John George Brown Galleries John George Brown (November 11, 1831 - February 8, 1913), American painter, was born in Durham, England, on 11 November 1831. He studied at Newcastle-on-Tyne, in the Edinburgh Academy, and after moving to New York City in 1853, he studied with Thomas Seir Cummings at the schools of the National Academy of Design, of which he became a member in 1863.New International Encyclopedia He was its vice-president, 1899-1904, and originated the idea of the removal of the Academy to a new site in 110th Street. In 1866 he became one of the charter members of the Water-Color Society, of which he was president from 1887 to 1904. He generally confined himself to representations of street child life, bootblacks, newsboys, etc.; his Passing Show (Paris, Salon, 1877) and Street Boys at Play (Paris Exhibition, 1900) are good examples of his popular talent. Brown's art is best characterized as British genre paintings adapted to American subjects. Essentially literary, it is executed with precise detail, but is poor in color, and more popular with the general public than with connoisseurs.
Jan van Beers
(22 February 1821 - 14 November 1888) was Flemish poet born in Antwerp. He is usually referred to as "van Beers the elder" to distinguish him from his son, Jan van Beers, the painter. Van Beers was essentially a Netherlander, though politically a Belgian, expressing his thoughts in the same language as any North Netherland writer. In fact, the poems of Jan van Beers are perhaps more popular in the Netherlands than in Belgium, and of many of them there exist more editions printed in the Netherlands than in his political fatherland. Van Beers started life as a teacher of Dutch language and literature, first at Mechelen, then at Lier, and in 1860 was appointed a professor of both at the Athenaeum (high school) in Antwerp, where he had also been a sub-librarian in the communal library. Van Beers as a teacher was early in the field, with Hendrik Conscience, Willems and others, when the Flemish movement began. He composed a Dutch grammar (1852), which, in enlarged editions, still holds the field, and a volume of selections from Dutch authors, both books being so much appreciated that the Belgian government made them text-books in the public schools. Van Beers's historical poems, the principal of which is, perhaps, Jakob Van Maerlant (Amsterdam, 1860), helped the Flemish revival in Belgium as powerfully as his school-books. He is best known, however, as the writer of ballads and songs. Jongelingsdroomen ("A Young Man's Dreams") first appeared at Antwerp and Amsterdam in 1853. These poems were followed by Levensbeelden ("Life Figures or Pictures," Amsterdam, 1858) and by Gevoel en Leven ("Feeling Living," Amsterdam, 1869). His Rijzende Blaren ("Rising Leaves") first made its appearance at Ghent and Rotterdam in 1883.
