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 :. | La Gioconda (The Mona Lisa) | Regisol | Virgin and Child with St Anne and St John the Baptist | The Virgin of the Rocks | The Last Supper-l |

Marstrand, Wilhelm
Danish, 1810-1873 Danish painter and illustrator. He was a student of C. W. Eckersberg at the Kunstakademi in Copenhagen (1825-33). His art reflects his constant observation of the world around him, in particular middle-class society, and the narrative element dominated his pictures of crowds in the city streets. Throughout his life he sought inspiration from literature and the theatre. In his early genre painting Moving Day Scene (1831; Niv?, Nivaagaards Malsaml.) it was the popular novelty of vaudeville that interested him. The October Festival (1839; Copenhagen, Thorvaldsens Mus.) reveals how Marstrand's five-year stay (1836-41) in Italy opened his eyes to the classical ideal of beauty. It was, however, an ideal that found little response in contemporary Denmark, and he turned towards a more anecdotal and humorous approach. In Scene of Country Life (1843; Copenhagen, Kon. Dan. Kstakad.), painted as a set subject for the Kunstakademi, Marstrand took as his theme a scene from Erasmus Montanus, a play by the 18th-century Danish poet and playwright Ludvig Holberg. Thereafter Holberg's comedies provided an inexhaustible source that satisfied Marstrand's need to pursue his investigations of human character. Family life similarly interested him throughout his career, as in his Scene of Daily Life (1857; Copenhagen, Stat. Mus. Kst). Such group portraits as The Waagepetersen Family (1836; Copenhagen, Stat. Mus. Kst) show an equal concern to depict the quiet details of Danish domestic life. Marstrand continued to travel abroad in search of inspiration. His stay in Venice in 1853-4 was particularly important; his studies there of the great Venetian painters improved his understanding of the handling of colour, as seen clearly in the many historical and religious paintings of his last years. Of particular interest is his mural decoration of Christian IV's chapel in Roskilde Cathedral (1864-6) with scenes from the life of the Danish monarch. Marstrand's paintings have a certain facetiousness which often obscures a much deeper philosophical content. For this reason, it is his drawings that arouse more admiration.
