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 :. | Hi Hieronymus | Battle of Anghiari | St John in the Wilderness | Studies of horses | Study fur the Sforza-Reiterstandbild |

George French Angas
(1844-1932), was a portrait painter. was an English explorer, naturalist and painter. He was the eldest son of George Fife Angas, prominent in the establishment of the new colony of South Australia. Despite showing remarkable talent in drawing, he was placed in a London business house by his father. He left on a tour of Europe and in 1842 published his first book, "Rambles in Malta and Sicily". As a result of this experience, he turned his back on the world of commerce, and directed his training towards a study of natural history, anatomical drawing and lithography. Embarking on his travels, he was soon to find his acquired skills extremely useful. Angas painted some of the earliest views of South Australia. Arriving in Adelaide in January 1844, he joined Sir George Grey on an expedition into the interior. He soon began an extensive series of journeys to the Murray River lakes, Barossa Valley, Fleurieu Peninsula and the South East, presenting his impressions of the newly established colony ?C its inhabitants, landscape, and its flora and fauna. Following a trip to New Zealand he returned to South Australia in 1845 and travelled to Port Lincoln. In the following year he returned for a short while to England. His next journey in 1846 was to South Africa, where he spent two years in Natal and the Cape, working on a series of drawings and watercolours which were published in 1849 as The Kafirs Illustrated. In this book were views of Cape Town, Durban, Wynberg, Genadendal, Paarl and Somerset West and plates depicting the local ethnic groups such as Hottentots, Malays and Zulus. He married Alicia Mary Moran in 1849, the marriage producing four daughters. In 1853 he was appointed to a position at the Australian Museum in Sydney, eventually becoming Director and staying a total of seven years. He was in Sydney when gold was first discovered near Bathurst, New South Wales. Travelling there to record the gold diggings he executed a number of drawings of the scenes that he found. These were published in Sydney and subsequently in London. Angas returned to South Australia in 1860, and finally went back to England in 1863.
