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 Annunciation | Anatomy of the Schadels | Virgin of the Rocks | Leonardo there Vinci and Andrea del Verrocchio, madonna with the child and angels | Mona Lisa (La Gioconda) sdg |

Israel Silvestre
French Baroque Era Engraver, 1621-1691,called the Younger to distinguish him from his father, was a prolific French draftsman, etcher and print dealer who specialized in topographical views and perspectives of famous buildings. Orphaned at an early age, he was taken in by his uncle in Paris, Israel Henriet, an etcher and printseller, and friend of Callot. Between 1630 and 1650 Silvestre travelled widely in France and Italy, which he visited three times, and later worked up his sketches as etchings, which were sold singly and in series. His work, especially of Venetian subjects published in the 1660s, influenced eighteenth-century painters of vedute such as Luca Carlevaris and Canaletto, who adapted his compositions. In 1661 he inherited the stock of plates of his uncle, the printseller Israel Henriet, among which was a large part of the works of Jacques Callot, and many of those of Stefano della Bella. In 1662 he was appointed dessinateur et graveur du Roi and in 1673 he was appointed drawing-master to Louis, le Grand Dauphin. From 1668 he was granted workshop space in the galleries of the Louvre, where the practice of housing eminent artists and craftsmen was a tradition that was originated under Henri IV. Silvestre's atelier was large: he had at least two pupils who had careers as engravers, Franqois Noblesse and Meunier, and In 1670 Charles Le Brun recommended him for membership in the Acadeemie royale de peinture et de sculpture. In 1675 his son, the artist Louis Silvestre, was born at Sceaux.
