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 :. | The Last Supper | La Belle Ferronniere | Adoration of the Magi | Portrait of a Musician | Reverse side of the portrait of Ginevra de' Benci |

Alexander Mann
Alexander Mann (January 22, 1853 - January 26, 1908) was a Scottish landscape and genre painter. He was a member of New English Art Club and Royal Institute of Oil Painters. Alexander Mann was born in Glasgow, Scotland on January 22, 1853. He died in London on January 26, 1908. The second son of James Mann, merchant and collector, he took drawing lessons from the age of ten with Robert Greenlees (1820-94) and then attended evening classes at the Glasgow School of Art, where Greenlees was headmaster. In 1877 he went to Paris and enrolled at the Academie Julian, and then studied under Mihely Munk? - sy and from 1881 to 1885 under Carolus-Duran. From 1883-93 Mann exhibited in London at the Royal Academy, Royal Institute of Oil Painters, Fine Art Society, New Gallery, Ridley Art Club, New English Art Club and Society of British Artists, a society that appointed James McNeill Whistler its President in 1886. At the same year he was invited to become the first Scottish member of the New English Art Club and was joined by several of his friends, notably John Lavery, Thomas Millie Dow of the Glasgow Boys and Norman Garstin. Influenced by the Hague school and by Jules Bastien-Lepage, his picture A Bead Stringer, Venice gained an honorable mention at the Salon in 1885. After a public controversy over this painting when it was exhibited at the Royal Glasgow Institute, Mann settled in England, at West Hagbourne, Berkshire, and later in the neighboring village of Blewbury, where he painted a series of views of the Downs and portraits of country people. Mann traveled extensively in Britain, paying several visits to the coast in Angus and Fife, and to Walberswick, Suffolk.
