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 :. | Flower Studies | The Virgin of the Rocks | Portrait of Cecilia Gallarani | Portrait of a Lady at the Court of Milan (san05) | Horses with horsemen |

Peter Nicolai Arbo
(June 18, 1831 - October 14, 1892) was a Norwegian painter, who specialized in painting motifs from Norwegian history and images from Norse mythology. He is above all noted for Åsgardsreien, a dramatic motif based on a Norwegian folk legend and Valkyrie, which depicts a female figure from Norse mythology. Peter Nicolai Arbo grew up at Gulskogen Manor in Gulskogen, a borough in Drammen, Norway. He was the son of headmaster Christian Fredrik Arbo (1791-1868) and his wife Marie Christiane von Rosen. His brother Carl Oscar Eugen Arbo was a military medical doctor and a pioneer in Norwegian anthropologic studies. Arbo's childhood home, Gulskogen, was built in 1804 as a summer residence for his older cousin, lumber dealer and industrialist Peter Nicolai Arbo.Arbo started his art education with a year at the Art School operated by Frederick Ferdinand Helsted (1809-1875) in Copenhagen 1851-1852. After this, he studied at the art academy in Dusseldorf. From 1853 to 1855 he studied under of Karl Ferdinand Sohn, professor of The Dusseldorf School of Art, and from 1857-1858 under J. E. Henthen who was a battle and animal painter. At Dusseldorf he was for some time a private student of the history painter C. Mengelberg. He had contact with Adolph Tidemand and became a good friend of Hans Gude both of whom were professors at the art academy in Dusseldorf.
William Hoare
William Hoare of Bath RA (c. 1707 - 12 December 1792) was an English painter and printmaker, co-founder of the Royal Academy noted for his pastels. Born near Eye, Suffolk, Hoare received a gentlemanes education in Faringdon. He showed a marked aptitude for drawing and was sent to London to study under Giuseppe Grisoni, who had left Florence for London in 1715. When Grisoni returned to Italy in 1728, Hoare went with him, travelling to Rome and continuing his studies under the direction of Francesco Imperiali. He remained in Rome for nine years, returning to London in 1737/8. Failing to establish himself in London, Hoare settled in Bath, an expanding spa town popular with the wealthier classes. He obtained numerous commissions, the most important being for official portraits of social leaders of the day (including George Frideric Handel) and political men. There are several versions of most of these, suggesting that he had a studio, and they were further publicised by the production of mezzotints by leading engravers of the day. Hoare himself was a delicate etcher and published a number of private plates, mostly of family and friends, including Miss Hoare (probably Mary), Christopher Anstey and the 3rd Duke of Beaufort. His pastels were influenced by Rosalba Carriera.
Jean-Baptiste Francois Desoria
Jean-Baptiste François Desoria (1758-1832). Both once enjoyed considerable renown among the elite of the Paris Enlightenment; today their names are barely known. Jean-Baptiste François Desoria (1758-1832), born in Paris, was, with the exception of some portraiture, primarily a history painter in the Neo-Classical style of his slightly older contemporary, Jacques-Louis David. Constance Pipelet, born in Nantes in 1767, was a surgeon's wife (later divorced) turned writer and librettist; she was noted primarily for her opera Sapho and her Epître aux femmes ( Epistle to the Women). Like her French predecessor of some four centuries earlier, Christine de Pizan, Constance Pipelet celebrated in writing the intellectual achievements of women.
