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 Portinari Altarpiece | The madonna with the Children | anna sjalv tredje | The Virgin and St Anne | The master of the Pala Sforzesca attributed |

VROOM, Hendrick Cornelisz.
Dutch Baroque Era Painter, ca.1563-1640. He was one of the founders of Dutch marine painting. Painter and draughtsman. By his own account, he received his early training in Delft, home of his mother's family. Van Mander reports that Hendrick's stepfather, like his father a ceramic artist, forced him to work as a decorator of ceramic vessels, which caused the young artist to leave home and embark on extensive travels in Spain and Italy. After working for ecclesiastical patrons in Florence and Rome, he was employed for at least two years (c. 1585-7) by Cardinal Ferdinando de' Medici, who in October 1587 succeeded Francesco I as Grand Duke of Tuscany. Ferdinando's keen interest in ships and the navy seems to have been a determining factor in Vroom's choice of subject-matter. According to Lanzi, he was known in Rome as 'Lo Spagnolo' (since he had arrived there from Spain). Among his earliest works may be a group of marine paintings attributed to him (Rome, Villa Colonna). His friendship in Rome with Paul Bril, mentioned by van Mander, had no effect on Hendrick's painting style, but Bril's influence is discernible in a group of landscape drawings
