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 :. | Portrait of Ginevra de Benci | Madonna Litta ey | Buste one frontal to seeing man and head of a Lowen | Madonna Litta (detail sdg | Virgin of the Rocks |

Pietro Fragiacomo
(Pirano deIstria (Trieste), 1856 - Venice, 1922) was an Italian painter. Born at Pirano deIstria near Trieste, Fragiacomo moved with his family to Venice, where he enrolled at the Academy of Fine Arts in 1878 after a period as a worker in Treviso. He then abandoned his studies barely one year later to devote himself more freely to painting from life, often in the company of his friend the painter Giacomo Favretto. He won a bronze medal at the Universal Exhibition of 1889 in Paris and took part in the Munich International Exhibition of the same year, as well as later editions. Drawing inspiration from the Venetian lagoon and always characterised by a crepuscular sense of nature, his landscapes took on Symbolist overtones at the end of the century. He won the Prince Umberto Prize at the Milan Triennale of 1891 and was a regular participant from 1895 to 1922 at the Venice Biennale, which held a solo show of his work in 1910 and a posthumous retrospective in 1924.
Conrad Martens
England/Australia Painter , 1801-1878 Australian painter, lithographer and librarian of English birth. Son of a London merchant, he studied c. 1816 under Copley Fielding. His training was as a watercolourist and his most important works are watercolours, although he also produced paintings in oils. His early work displays the taste then current for the Picturesque. Francis Danby, David Cox and Turner were artists he admired. Martens left for India in 1832 or 1833 but at Montevideo joined Charles Darwin's expedition, replacing Augustus Earle as topographical draughtsman aboard the Beagle. The work strengthened his observation of detail and skill as a draughtsman. He left the expedition in October 1834 and, travelling via Tahiti and New Zealand, arrived in Sydney in April 1835. There he worked as a professional artist, in the 1840s and 1850s producing lithographic views of the Sydney area to augment his income. In 1863 he was appointed Parliamentary Librarian, which secured his finances. The skills he had acquired aboard the Beagle helped to gain him commissions to depict the estates around Sydney. However, his admiration for Turner, and with this the desire to elevate landscape as a subject, prompted him to subordinate line to mood in a Romantic treatment of the landscape. His thoughts were clearly stated in a lecture on landscape painting given in 1856 at the Australian Library, Sydney (see Smith, 1975).
