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 :. | Reverse side of the portrait of Ginevra de' Benci | Madonna with the Yarnwinder | The Annunciation | Madonna and Child | Interior view of the Schadels |

Georges Michel
French Painter, 1763-1843 French painter. He came from a humble background, his father being an employee at the market of Les Halles in Paris. At an early age, a farmer general, M. de Chalue, took an interest in him and found him a place with the curate of Veruts, on the plain of Saint-Denis, north of Paris. It was here that he first developed a love of the countryside. In 1775 he was apprenticed to a mediocre history painter called Leduc, but he preferred to go off and sketch out of doors. In order to assist him, M. de Berchigny, Colonel in the Hussars, engaged him in his regiment garrisoned in Normandy and arranged for him to take lessons in art. He remained there for more than a year and then returned to Paris, where he worked with M. de Grammont-Voulgy, who was Steward to the brother of Louis XVI.

SCHRIECK, Otto Marseus van
Dutch Baroque Era Painter, 1619-1678 Dutch painter. According to Houbraken, he travelled to Italy and stayed in Rome and Florence with the painters Matthias Withoos and Willem van Aelst, the latter his pupil at the time. Among his patrons were Ferdinando II de' Medici, Grand Duke of Tuscany (reg 1621-70). Van Hoogstraten claimed that he met van Schrieck in Rome as late as 1652. In Rome, van Schrieck was a member of the Schildersbent. About 1657 he returned with van Aelst to Amsterdam, where he had a small property and got married on 25 April 1664. An inventory of the contents of his house was made in July 1678, shortly after his death, in which more than 300 paintings are listed. Besides his own paintings, there were works by Cornelis van Poelenburch, Simon de Vlieger, Ludolf Bakhuizen, Jan Wijnants, Lucas van Leyden
