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 Virgin and the Nino with Holy Ana | Benois Madonna | Mona Lisa (detail) dyk | The Annunciation | The Virgin of the rocks |

MANFREDI, Bartolomeo
Italian Baroque Era Painter, 1582-1622 Italian painter. In the 17th century he was known throughout Italy and beyond as Caravaggio's closest follower and his works were highly prized and widely collected. More than simply aping Caravaggio's style, Manfredi reinterpreted his subjects and rendered new ones, drawing upon Caravaggio's naturalism and dramatic use of chiaroscuro. His paintings were often praised by his contemporaries as equal to Caravaggio's and he was subsequently emulated and imitated by other Roman Caravaggisti during the 1610s and 1620s. Yet by the 18th century his works were forgotten or confused with those of Caravaggio himself,
Jean Marc Nattier
1685-1766 French Jean Marc Nattier Gallery Brother of Jean-Baptiste Nattier. As well as being taught by his father, he trained with his godfather, Jean Jouvenet, and attended the drawing classes of the Academie Royale, where in 1700 he won the Premier Prix de Dessin. From around 1703 he worked on La Galerie du Palais du Luxembourg. The experience of copying the work of Rubens does not, however, seem to have had a liberating effect on his draughtsmanship, which was described by the 18th-century collector Pierre-Jean Mariette as cold. Nattier was commissioned to make further drawings for engravers in the early part of his career, including those after Hyacinthe Rigaud famous state portrait of Louis XIV (1701; Paris, Louvre) in 1710, which indicates that he had established a reputation while he was still quite young. Although he was offered a place at the Academie de France in Rome on the recommendation of Jouvenet, Nattier preferred to remain in Paris and further his career. In 1717 he nevertheless made a trip to Holland, where he painted portraits of Peter the Great and the Empress Catherine (St Petersburg, Hermitage). The Tsar offered Nattier work at the Russian court, but the artist declined the offer. He remained in Paris for the rest of his life.
