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 :. | Jacopo Bellini | Small devotional picture by Verrocchio | Portrat of a musician | la scapigliata | The Virgin of the rocks |

Marmion, Simon
French-born Flemish Northern Renaissance Painter, ca.1425-1489 French illuminator and painter. He was trained in Amiens and established a productive workshop in Valenciennes, but at the end of his career appears to have had connections with manuscript painting in the southern Netherlands. Although no signed or documented works survive, many illuminated manuscripts and some panel paintings have been convincingly attributed to him and his workshop. On the basis of these he has been recognized as an important figure in the development of both French and Netherlandish painting.

henry wadsworth longfellow
1807-C82, American poet, b. Portland, Maine, grad. Bowdoin College, 1825. He wrote some of the most popular poems in American literature, in which he created a new body of romantic American legends. Descended from an established New England family, after college he spent the next three years in Europe, preparing himself for a professorship of modern languages at Bowdoin, where he taught from 1829 to 1835. After the death of his young wife in 1835, Longfellow traveled again to Europe, where he met Frances Appleton, who was to become his second wife after a long courtship. She was the model for the heroine of his prose romance, Hyperion (1839). From 1836 to 1854, Longfellow was professor of modern languages at Harvard, and during these years he became one of an intellectual triumvirate that included Oliver Wendell Holmes and James Russell Lowell. Although a sympathetic and ethical person, Longfellow was uninvolved in the compelling religious and social issues of his time; he did, however, display interest in the abolitionist cause.
