LEONARDO da Vinci
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.

(4 December 1862 - 28 June 1916) was an Australian artist and member of the Dawn and Dusk Club.
Although christened "Francis Mahony", he later added 'Prout' and usually signed his work 'Frank P. Mahony'.
Mahony was born in Melbourne, third surviving child of Timothy Mahony, an Irish-born contractor, and his Cornish second wife Elizabeth, Johns. Mahony was taken to Sydney when 10 years old and studied at the Academy of Art under Giulio Anivitti.Mahony's work was accepted by The Bulletin and he became known for his excellent drawings of horses. In 1889 his oil painting Rounding up a Straggler, was bought for the Art Gallery of New South Wales; in 1896 The Cry of the Mothers was also purchased.Mahony did a lot of illustrative work for the Picturesque Atlas of Australia, Victoria and its Metropolis, the Antipodean and other magazines of the period, and was also responsible for some of the illustrations to Barcroft Boake's Where the Dead Men Lie.Eugene Isabey
Eugene Isabey Galleries
Born in Paris, the son of Jean-Baptiste Isabey, a painter as well, Eug??ne Isabey studied and worked at the Louvre Museum. Early in his career his paintings consisted of mostly watercolor landscapes. In 1820, he travelled to Normandy and Britain painting land and seascapes.
Isabey journeyed with the French Expedition to Algiers in 1830 as an illustrator. Yet, the trip's paintings sold poorly on the market and encouraged him to switch to narrative and historical painting. He was later selected to become one of Louis-Philippe??s court painters.marin mersenne
French mathematician,philosopher and theorist. One of the leading French thinkers of the 17th century, he lived in Paris from 1619 as a Jesuit priest. His work is central to the academic and scientific movements of his time, and a major part of it is devoted to music. On the basis of practical experiment and observations, he made important discoveries concerning the nature and behaviour of sound, which are the foundation of the science of acoustics in later times. He also wrote on the theory and practice of music. His principal musical treatise is the Harmonie universelle
