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 :. | Detail of Madonna of the Rocks | Last Supper | The Baptism of Christ | Pod of cherry and forest strawberry | Virgin of the Rocks (mk10) |

James Duffield Harding
English Painter, ca.1797-1863 English painter, engraver and writer. He received his first lessons in painting from his father, J. Harding (d 1846), who was a pupil of Paul Sandby. By 1807 the family had moved to Greenwich where Harding spent much of his time drawing and painting in Greenwich Park. In 1811 at the age of 14 he exhibited for the first time at the Royal Academy. He had lessons in watercolour painting from Samuel Prout and in 1816 he won the Society of Arts silver medal for landscape painting.
Bertel Thorvaldsen
1770-1844 Copenhagen, He was a Danish/Icelandic sculptor. Thorvaldsen was born in Copenhagen in 1770 (according to some accounts, in 1768), the son of an Icelander who had settled in Denmark and there carried on the trade of a wood-carver. This account is disputed by some Icelanders, who claim Thorvaldsen was born in Iceland. Young Thorvaldsen attended Copenhagen's Royal Danish Academy of Art (Det Kongelige Danske Kunstakademi), winning all the prizes including the large Gold Medal. As a consequence, he was granted a Royal stipend, enabling him to complete his studies in Rome, where he arrived on 8 March 1797. Since the date of his birth had never been recorded, he celebrated this day as his "Roman birthday" for the rest of his life. Thorvaldsen's first success was the model for a statue of Jason, which was highly praised by Antonio Canova, the most popular sculptor in the city. In 1803 he received the commission to execute it in marble from Thomas Hope, a wealthy English art-patron. From that time Thorvaldsen's success was assured, and he did not leave Italy for sixteen years. In 1819 he visited his native Denmark. Here he was commissioned to make the colossal series of statues of Christ and the twelve Apostles for the rebuilding of Vor Frue Kirke (from 1922 known as the Copenhagen Cathedral) between 1817 and 1829, after its having been destroyed in the British bombardment of Copenhagen in 1807.
John Webber
(1751-1793), Landscape painter, was an English artist best known for his images of early Alaska and Hawaii. Webber was born on October 6, 1751 in London, educated in Switzerland and studied painting at Paris[2]. Webber served as official artist on Captain James Cook??s third voyage of discovery around the Pacific (1776-1780) aboard HMS Resolution. At Adventure Bay in January 1777 he did drawings of "A Man of Van Diemen's Land" and "A Woman of Van Diemen's Land". He also did many drawings of scenes in New Zealand and the South Sea islands. On this voyage, during which Cook lost his life in a fight in Hawaii, Webber became the first European artist to make contact with Hawaii, then called the Sandwich Islands. He made numerous watercolor landscapes of the islands of Kauai and Hawaii, and also portrayed many of the Hawaiian people. Back in England in 1780 Webber exhibited around 50 works at Royal Academy exhibitions between 1784 and 1792, and was elected an associate of the Royal Academy in 1785 and R.A. in 1791. Most of his work were landscapes. Sometimes figures were included as in "A Party from H.M.S. Resolution shooting sea horses", which was shown at the academy in 1784, and his "The Death of Captain Cook" became well known through an engraving of it. Another version of this picture is in the William Dixson gallery at Sydney. Webber died in London in 1793.
