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 :. | Six studies fur naked or clothed men | The Last Supper sgu | Madonna and Child with a Pomegranate et | Self Portrait | St John the Baptist t |

Bernard Hall
Artist, teacher, Director of Melbourne??s National Gallery and Felton Bequest advisor English-born Australian, 1859-1935 was an English-born Australian artist. Hall was born at Liverpool, England. The son of a Liverpool broker of the same family as Captain Basil Hall, writer of books of travel, he was well educated and grew up in an atmosphere of culture. He studied painting at South Kensington, Antwerp and Munich, and worked for some to years in London. He exhibited at the Royal Academy and was one of the original members of the New English Art Club. On the death of George Frederick Folingsby in 1891 he was appointed director of the National Gallery of Victoria at Melbourne, and began his duties in March 1892. He held the position for 43 years aria many of the well-known painters of Australia were trained by him in the gallery painting school. He also acted as adviser to the trustees for purchases for the gallery and art museum, and when the munificent bequest of Alfred Felton was received his responsibilities were much increased. In 1905 he went to England to make purchases under this bequest, and although the amount then placed in his hands was comparatively small, he made better use of what was available than any subsequent adviser of his time. After his return he was expected to advise on everything submitted that might find a place in an art museum and, although he never claimed to be an expert in all these things, he supplemented his knowledge with hard reading and made cornparatively few mistakes. Hall's own paintings were usually interiors, nudes, or paintings of still life. He was often represented at the Victorian Artists' and other societies' exhibitions and held several one-man shows, but he was kept so busily employed as director and adviser, that his paintings had to be done at week ends and during vacations. In February 1934 he again went to London as adviser to the Felton trustees and died there on 14 February 1935. He was married twice in 1894 to Miss E. M. Shuter and in 1912 to Miss G. H. Thomson, who with one son by the first marriage and two sons and a daughter by the second marriage, survived him. Hall was a tall man of distinguished appearance, courteous but slightly austere in manner, with strong convictions, and little sense of compromise. He was extremely conservative in almost everything from his art to his politics.
