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 :. | Adoration of the Magi | Detail of Madonna of the Rocks | The Virgin of the Rocks | Madonna and Child with a Pomegranate | Virgin and Child with St Anne |

WERTINGER, Hans
German painter (b. 1465, Landshut, d. 1533, Landshut) German painter and woodcutter. An artist as ambitious as Lucas Cranach I, he became one of Germany's first accredited court painters, working for the Dukes of Landshut in the triangular area defined by Ingolstadt, Straubing and Munich. The son of a functionary working for the Dukes, he was probably first taught by a certain Sigmund Gleism?ller (c. 1449-1511). Hans Mair (Mair von Landshut), who had come from Augsburg and had settled in Landshut, seems to have prompted him to work as a journeyman in Augsburg. His acquisition of citizen's rights in Landshut in 1491 suggests he was a master by that date. Mair seemingly procured him a series of commissions between 1497 and 1499 from Prince Bishop Philipp of Freising (1480-1541). The only work to survive from this period, however, is the large panel of the Life of St Sigismund (1498) in Freising Cathedral. It retains the deep tones associated with Augsburg painting, and its shape, with a pointed arch at the top, must also have been developed in Augsburg. As in Mair's work, several scenes are assembled in the arch and the side sections, creating a cramped Late Gothic framing architecture,
Isaac Israels
Dutch, 1865-1934 Son of Jozef Israëls. He was largely self-taught, showing precocious talent and attending the Academie in The Hague in 1878-80. His first paintings date from 1880-84 and include a self-portrait, portraits of women and military subjects such as Bugle Practice. They were composed in the studio in a precise style, soft grey and brown tones predominating, showing the influence of the Hague school. In 1887 Israels moved to Amsterdam, where he was at the centre of the Tachtigers of writers and painters. Among his friends were George Hendrik Breitner, Lodewijk van Dyssel, Frans Erens, Max Liebermann, Jan Pieter Veth and Jan Voerman. In Amsterdam, after a brief and abortive period at the Rijksacademie, he sought a more fluent technique with which to record contemporary life. His drawings and watercolours are predominantly of cafes, cabarets, dance halls and the street life of Amsterdam. In 1889 he visited Paris, where he met St phane Mallarm, Berthe Morisot, Odilon Redon and Emile Zola. In 1894 he painted Three Servant Girls, the first of his plein-air pictures. From then on he applied transparent colours to capture the fleeting effects of light in oil, watercolour and pastel. His oils were painted in flat broad strokes. For the rest of his life he employed his very personal Impressionist style, which emphasized the interplay of light, colour, line and movement. His favourite subjects were beach, street and park scenes
