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 :. | Cartoon | The Virgin and Child with Anne (mk05) | Portrait of a Lady at the Court of Milan (san05) | The Baptism of Christ | The Battle of Anghiari |

Paul Philippoteaux
artist, born in Paris, France, 27 January, 1846 was a French artist. He is best known for a cyclorama of the Battle of Gettysburg.Paul Philippoteaux was born in Paris, the son of the French artist Henri Emmanuel Felix Philippoteaux. His education was at the Coll??ge Henri-IV, the École des Beaux-Arts in Paris, and in the studio of his father, as well as the studios of Leon Cogniet, and Alexander Cabanal. He became interested in cycloramas and in collaboration with his father created The Defence of the Fort d'Issy in 1871. Other works included Taking of Plevna (Turko-Russian War), the Passage of the Balkans, The Belgian Revolution of 1830, Attack in the Park, The Battle of Kars, The Battle of Tel-el-Kebir, and the Derniere Sortie.He was commissioned by a group of Chicago investors in 1879 to create the Gettysburg cyclorama. He spent several weeks in April 1882 at the site of the Gettysburg Battlefield to sketch and photograph the scene, and extensively researched the battle and its events over several months. Local photographer William H. Tipton created a series of panoramic photographs shot from a wooden tower erected along present-day Hancock Avenue. The photos, pasted together, formed the basis of the composition. Philippoteaux also interviewed several survivors of the battle, including Union generals Winfield S. Hancock, Abner Doubleday, Oliver O. Howard, and Alexander S. Webb, and based his work partly on their recollections.Philippoteaux enlisted a team of five assistants,
