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 :. | anna sjalv tredje | Anatomical study of the brain and the scalp | Self Portrait | The master of the Pala Sforzesca attributed | Annunciation sgt66 |

Jan Matejko
Polish Painter, 1838-1893 He studied from 1852 to 1858 at the School of Fine Arts in Krakew and, during this time, started exhibiting historical paintings with the Society of Friends of the Fine Arts there (e.g. Sigismund I Bestowing Nobility on the Professors of the University of Krakew in 1535 (1858; Krakew, Jagiellonian U., Mus. F.A.). After studying in Munich (1859) under the history painter Hermann Anschetz (1802-80) and then briefly and less successfully in Vienna, Matejko returned to Krak?w, where he was based for the rest of his life. In 1860 Matejko issued an illustrated album, Ubiory w Polsce (later editions 1875 and 1901), a project reflecting his intense interest in historical records of all kinds and his desire to promote such interest among the Polish people in an effort to intensify their patriotic feelings. This role first became widely associated with Matejko with his painting of Stanczyk (1862; Warsaw, N. Mus.), the court jester to King Sigismund I (1437-1548), to whom Matejko gave his own features. The jester is presented as a symbol of the nation's conscience
BIJLERT, Jan van
Dutch painter, Utrecht school (b. 1597/98, Utrecht, d. 1671, Utrecht) Dutch painter. He was the son of the Utrecht glass painter Herman Beerntsz. van Bijlert (c. 1566-before 1615). Jan must have trained first with his father but was later apprenticed to the painter Abraham Bloemaert. After his initial training, he visited France and travelled to Italy, as did other artists from Utrecht. Jan stayed mainly in Rome, where he became a member of the Schildersbent; he returned to Utrecht in 1624. In Rome he and the other Utrecht artists had come under the influence of the work of Caravaggio; after their return home, this group of painters, who became known as the UTRECHT CARAVAGGISTI, adapted the style of Caravaggio to their own local idiom. The Caravaggesque style, evident in van Bijlert's early paintings.
