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 :. | Studies fur the adoration of the Konige | Head of a girl | Anatomical studies of the basin of the Steibeins and the lower Gliedmaben of a woman and study of the rotation of the arms | The Annunciation | Muscles and bone of leg and Hufte |

jean-Baptiste-Simeon Chardin
1699-1779 was an 18th-century French painter. He is considered a master of still life.Chardin was born in Paris, the son of a cabinetmaker, and rarely left the city. He lived on the Left Bank near Saint-Sulpice until 1757, when Louis XV granted him a studio and living quarters in the Louvre.Chardin entered into a marriage contract with Marguerite Saintard in 1723, whom he did not marry until 1731.He served apprenticeships with the history painters Pierre-Jacques Cazes and Noël-Nicholas Coypel, and in 1724 became a master in the Academie de Saint-Luc. Upon presentation of The Ray in 1728, he was admitted to the Academie Royale de Peinture et de Sculpture. The following year he ceded his position in the Academie de Saint-Luc. In November of 1731 his son Jean-Pierre was baptized, and a daughter, Marguerite-Agn's, was baptized in 1733. In 1735 his wife Marguerite died, and within two years Marguerite-Agn's had died as well.Beginning in 1737 Chardin exhibited regularly at the Salon. He would prove to be a 'dedicated academician', regularly attending meetings for fifty years, and functioning successively as counsellor, treasurer, and secretary, overseeing in 1761 the installation of Salon exhibitions. In 1744 he entered his second marriage, this time to Françoise-Marguerite Pouget. The following year a daughter, Angelique-Françoise, was born, but she died in 1746. In 1752 Chardin was granted a pension of 500 livres by Louis XV. At the Salon of 1759 he exhibited nine paintings; it was the first Salon to be commented upon by Denis Diderot, who would prove to be a great admirer and public champion of Chardin's work.Beginning in 1761, his responsibilities on behalf of the Salon, simultaneously arranging the exhibitions and acting as treasurer, resulted in a diminution of productivity in painting, and the showing of 'replicas' of previous works.In 1763 his services to the Academie were acknowledged with an extra 200 livres in pension. In 1765 he was unanimously elected associate member of the Academie des Sciences, Belles-Lettres et Arts of Rouen, but there is no evidence that he left Paris to accept the honor.By 1770 Chardin was the 'Premiere peintre du roi', and his pension of 1,400 livres was the highest in the Academy.In 1772 Chardin's son,
