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 :. | Mona Lisa | You branching of the Blutgefabe, anatomical figure with heart kidneys and Blutgefaben | Madonna and Child with St Anne and the Young St John | The muscles of Thorax and shoulders in a lebnden person | Annunciation |

Alexander Wilson
Alexander Wilson (July 6, 1766 - August 23, 1813) was a Scottish-American poet, ornithologist, naturalist, and illustrator. Wilson was born in Paisley, Scotland, the son of an illiterate distiller. In 1779 he was apprenticed as a weaver. His main interest at this time was in writing poetry (Robert Burns was seven years older than Wilson). Some of Wilson's work - commenting on the unfair treatment of the weavers by their employers - got him into trouble with the authorities. The "golden age of Renfrewshire song" is embodied in the persons of Wilson and Robert Tannahill. Alexander Wilson was born near the Hammils, a broad if not steep waterfall in Paisley where the River Cart skirts Seedhill. It does indeed appear to be the case, as William Motherwell states, that a great amount of literary activity began in Paisley around this time. Illustration from "An American ornithologyIn May 1794 Wilson left Scotland with his nephew to find a better life in America. Wilson obtained employment as a schoolteacher in Milestown, near Philadelphia. In 1801 he left Milestown and found a new teaching post in Gray's Ferry, Pennsylvania; Wilson took up residence in nearby Kingsessing. It was here that he met the famous naturalist William Bartram who developed Wilson's interest in ornithology. In 1802 Wilson decided to publish a book illustrating all the North American birds. With this in mind he traveled widely, watching and painting birds and collecting subscribers for his book. The result was the nine-volume American Ornithology (1808-1814), illustrating 268 species of birds, 26 of which had not previously been described. He died during the writing of the ninth volume, which was completed and published after his death by his friend George Ord. Wilson lies buried next to Ord at Gloria Dei Church cemetery in Philadelphia, Pennsylvania.
