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 :. | The madonna with the Children | St Jerome sgyu | The Benois Madonna | Adoration of the Magi (mk08) | Madchenkopf with confused hair |

Anton mauve
Dutch Painter, 1838-1888 He came from a large family of clergymen in the province of North Holland. At the age of 16 he was apprenticed to the animal painter Pieter Frederik van Os (1808-92): animals (especially sheep, but also cows and horses) became Mauve's preferred theme. He then trained for a few months with Wouterus Verschuur, who gave him his love of horses, in the style, at least, of Paulus Potter and Philips Wouwerman.
Hugh Douglas Hamilton
(c. 1740 - 10 February 1808) was an Irish portrait-painter. Biography Hamilton was born in Crow Street, in Dublin, Ireland, in 1740, the son of a peruke maker. Unfortunately there is very little concrete evidence for his earlylife, apart from his own drawings. He studied art under Robert West at the Dublin Society House - and won some early success with crayon and pastel portraits there. He was very adept at building relationships with patrons from the early days, taking up with the famous La Touche banking family of Dublin, who had close ties with the Bank of Ireland. Very little is known of Hamilton's career between 1756 and 1764, when he moved to London. Hamilton found great success in London through his pastel oval portraits, portraying royalty, politicians and celebrities of the day through this medium. Hamilton was often overwhelmed with orders, including commissions from the British royal family - such as Queen Charlotte (1764) and others now in the British Royal Collection. He showed with the Society of Artists and the Free Society of Artists from the mid-1760s to the mid-1770s. From the mid-1770s on, Hamilton became very interested in a softer, more textural form of pastel "fresco", in which he blended crayons and chalk to further the pastel's ability to imitate flesh. In 1779 he travelled to Italy, where he remained for the next twelve years, occasionally visiting Florence but mainly based in Rome, where he knew Antonio Canova. On the advice of artist John Flaxman Hamilton turned to oil painting, and achieved great success with small oval portraits of Irish and British visitors. His portraits of this period include those of Dean Kirwan (displayed at the Royal Dublin Society), George John, 2nd Earl Spencer, Countess Cowper (1787), and the exiled Charles Edward Stuart ( Lord Edward, 1785). In 1791 Hamilton returned to Dublin, where he died. In 1796 he painted Lord Edward Fitzgerald, the Irish revolutionary.
