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 :. | Madonna with the carnation | Portrat of a musician | Mona Lisa (detail) r y | The annunciation | Madonna and Child with a Pomegranate et |

William Barak
Australian Aboriginal, ca.1824-1903 was the last traditional ngurungaeta (elder) of the Wurundjeri-willam clan, based around the area of present-day Melbourne, Australia. He became an influential spokesman for Aboriginal social justice and an important informant on Wurundjeri cultural lore. Barak was born in the early 1820s at Brushy Creek near present-day Croydon, in the country of the Wurundjeri people. His mother, Tooterrie, came from the Nourailum bulluk at Murchison, Victoria. His father, Bebejern, was an important member of the Wurundjeri clan. Beruk was said to have been present when John Batman met with the tribal elders to 'purchase' the Melbourne area in 1835. Before he died he described witnessing the signing of the treaty in a ceremony he called a tanderem. Ninggalobin, Poleorong and Billibellary were the leading song makers and principal Wurundjeri leaders in the Melbourne region. European colonisation had caused disruptions to initiation ceremonies. In response these three men gathered at South Yarra in the late 1830s and inducted the young William Barak into Aboriginal lore. This entailed formally presenting Barak with the symbols of manhood: strips of possumskin tied around his biceps; the gombert around his neck; given his ilbi-jerri, a sharp and narrow bone or nose-peg; and his branjep, the apron worn by men to cover their genitals. At the end of the ceremony Barack presented his uncle, Billibellary, a possumskin cloak. Beruk attended the government's Yarra Mission School from 1837 to 1839. When he joined the Native Mounted Police in 1844, he was given the name of William Barak. He was Police Trooper No.19. In early 1863, Barak moved to Coranderrk Station, near Healesville, Victoria with about thirty others. Upon the death of Simon Wonga in 1875, Barak became the Ngurungaeta of the clan. He worked tirelessly for his people and was a successful negotiator on their behalf. He was a highly respected man and leader, with standing amongst the Indigenous people and the European settlers. Figures in possum-skin cloaks, 1898 by William Barak.Barak is now best remembered for his artworks, which show both traditional Indigenous life and encounters with Europeans. Most of Barak's drawings were completed at Coranderrk during the 1880s and 1890s. They are now highly prized and exhibited in leading public galleries in Australia. His work is on permanent display in the National Gallery of Victoria Ian Potter Centre at Federation Square, Melbourne. Ceremony (1895) is housed at the Ballarat Fine Art Gallery. Barak died at Coranderrk in 1903 and is buried at the Coranderrk cemetery.

Donato Creti
(1671-1749) was an Italian painter of the Rococo period, active mostly in Bologna. Born in Cremona, he moved to Bologna, where he was a pupil of Lorenzo Pasinelli. He is described by Wittkower as the "Bolognese Marco Benefial", in that his style was less decorative and edged into a more formal neoclassical style. It is an academicized grand style, that crystallizes into a manneristic neoclassicism, with crisp and frigid modeling of the figures. Among his followers were Aureliano Milani, Francesco Monti, and Ercole Graziani the Younger. Two other pupils were Domenico Maria Fratta and Giuseppe Peroni
