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 Baptism of Christ | Saint John the Baptist | Lady with Emine | John the Baptist | Leda |

Luca Carlevarijs
Luca Carlevarijs or Carlevaris (20 January 1663 - 12 February 1730) was an Italian painter and engraver of landscapes (vedutista). Carlevarijs was born in Udine, but worked mostly in Venice. His vedute of Venice are among the earliest Baroque depictions of the city. He was influenced by the Dutch painter active in Rome, Caspar van Wittel (often called Vanvitelli). The painters Canaletto and Antonio Visentini are said to have been highly influenced by or pupils of his. Johan Richter did work with him. Also called Luca Casanobrio or Luca di Ca Zenobri, for his patronage by the latter family. He painted landscapes, sea-pieces, and perspective views. He completed over a hundred etchings of views in Venice, which give an exact representation of the principal places in that city. He died in Venice.
George Turner
1750-1843. Turner was born in Cromford, Derbyshire in England, but then moved to Derby with his family. He showed an early talent for music and art - encouraged by his father Thomas Turner, who although a tailor by profession was also an art enthusiast. Turner was largely self-taught and went on to become a professional painter and art teacher. A quiet scene in Derbyshire (1885)Turner lived in Derbyshire all his life. In 1865 he married Eliza Lakin (1837 - 1900), becoming a part-time farmer and raising four children at Walnut farm in Barrow upon Trent.[1] After Eliza's death in 1900, he moved to Kirk Ireton and later married fellow artist Kate Stevens Smith (1871-1964) - they set up home in Idridgehay where he died in 1910. His son William Lakin Turner (1867-1929) also became a landscape oil painter of repute. Turner worked in oils and painted bucolic scenes mainly of his native Derbyshire, leaving an important legacy of hundreds of pictures depicting the English countryside before the coming of mechanisation, the motor car and urban expansion. His work was exhibited in Nottingham and Birmingham. Turner served on the Art Committee of Derby Art Gallery and both his and his son's paintings are included in the city's collection.
