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 :. | The Verkundigung | The Baptism of Christ (detail) sg | St Jerome sgyu | Annunciation (detail) dfe | Study fur the Sforza-Reiterstandbild |

EYCK, Hubert van
Flemish Northern Renaissance Painter, ca.1370-1426
Gentile da Fabriano
Fabriano ca 1370-Rome 1427 Italian painter, one of the outstanding exponents of the elegant international Gothic style. In 1409 he worked in the Doge's Palace, Venice, painting historical frescoes that subsequently perished. In 1422 he was in Florence where he created his most celebrated painting, the resplendent Strozzi altarpiece (Uffizi). Gentile painted in the spirit and the manner of the older school, with glowing color and lavish use of gilt, thereby achieving a jewellike, courtly style. By 1425 he had responded to the new Florentine realism. His refined forms yielded to a sturdier rendering of figures in the Quaratesi altarpiece (panels are now in the Uffizi; Vatican; National Gall., London; and National Gall. of Art, Washington, D.C.). From 1425 until his death he worked in Siena, Orvieto, and Rome. Gentile died in Rome before the completion of the frescoes of St. John the Baptist in the Lateran Basilica.
Johan Christoffer Boklund
(15 July 1817 - 9 December 1880) was a Swedish history, genre, and portrait painter from Kulla-Gunnarstorp in Scania.He was the son of a gardener. At the age of fifteen, Boklund came to Lund, where he worked on illustrations for Sven Nilsson's works on Scandinavian fauna (under the supervision of Magnus Körner). He then became a student at the Royal Danish Academy of Fine Arts in Copenhagen where J. L. Lund was his teacher. In 1837, Boklund went to Stockholm and began studying at the Royal Swedish Academy of Arts. He made a living as a lithograph and drawing teacher, and produced several small genre paintings of the everyday life (such as Flicka med blomster (English: Girl with flowers) and Köksinteriör (English: Kitchen interior)) and history paintings of the 17th century (such as Gustaf Adolfs afsked från Maria Eleonora (English: Gustaf Adolf's farewell from Maria Eleonora), which was awarded with a medal at the academy). Together with fellow Swedish painter Johan Fredrik Höckert, Boklund traveled to Munich in Germany in 1846 and stayed there for eight years. During the summers he went on study trips to Bavaria, Tyrol, and northern Italy. During this period, Boklund primarily devoted his painting to the history genre with subjects from the 17th century, but he also made some paintings depicting picturesque and architectural interior. In 1853, he sent his painting Den nyfikne trumpetaren (English: The curious trumpet player) home to Sweden and it earned him a scholarship from the government. This allowed Boklund to move to Paris, where he worked at Thomas Couture's atelier from 1854 to 1855. In December 1855 he returned to Sweden.
