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 :. | Virgin of the Rocks | The annunciation | The Last Supper | Ceiling decoration yy | Woman portrait |

Johann Michael Rottmayr
Austrian,1654-1730 Austrian painter and draughtsman. He is most notable for large-scale religious and secular decorative schemes, and his career heralded the important 18th-century German contribution to late Baroque and Rococo fresco painting. He was probably taught by his mother, who was a painter of wooden sculpture. Between 1675 and 1687-8 he was in Venice as a pupil and assistant of the Munich artist Johann Carl Loth, whose studio attracted many painters from Austria and southern Germany. It is possible that Rottmayr also visited other Italian cities, in particular Bologna and Rome. He returned to Salzburg in the late 1680s a mature painter and immediately received commissions for panels and frescoes. In 1689 he painted mythological scenes for the Karabinierisaal at the Residenz in Salzburg (in situ); in composition and style these are close to high Baroque models, particularly the work of Pietro da Cortona and Peter Paul Rubens. Such models, as well as the example of Loth, and Venetian painting, had an important influence on Rottmayr's panel paintings of this period, for example the Sacrifice of Iphigenia (c. 1691; Vienna, Belvedere) or St Agnes (1693-5) and St Sebastian (1694; both Passau, Cathedral). In these, the solidity of the figures is emphasized through the use of intense colours. For Rottmayr, however, the rational development of the figures and the composition was less important than the overall effect achieved by the use of colour. Incorrect details of anatomy and perspective found compensation in greater expressiveness, mainly conveyed by gesture and pose. Rottmayr's images are filled with plastic elements, creating a staccato effect. Several very important early commissions paved the way for Rottmayr's move to Vienna in the late 1690s.

Arthur streeton
1867 - 1943 Australian painter. He moved to Melbourne with his family when he was seven. In 1882 he enrolled as a student of drawing at the evening classes of the National Gallery School of Design and briefly in the School of Painting, but he had no sustained formal instruction in painting. At the same time he began making watercolour sketches of Melbourne, and by 1886 his skill led to an apprenticeship as a lithographer to George Troedel and Co. of Collins Street. The most important early influence on Streeton was Tom Roberts, who had returned to Melbourne from Europe in 1885. With Frederick McCubbin, Streeton and Roberts painted en plein air at a temporary camp at Box Hill, forming what became known as the HEIDELBERG SCHOOL. A little later Streeton established the first permanent artists' camp at Eaglemont, north-west of Melbourne, overlooking the Yarra Valley, where he painted some of his most memorable works.
