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 :. | Virgin of the Rocks | Lady with Ermine | The Madonna of the Carnation g | Study fur the Sforza monument | Leda and the Swan |

Baron Pierre-Narcisse Guerin
(13 May 1774 - 6 July 1833) was a French painter. Guerin was born in Paris. A pupil of Jean-Baptiste Regnault, he carried off one of the three grands prix offered in 1796, in consequence of the competition not having taken place since 1793. In 1799, his painting Marcus Sextus (Louvre) was exhibited at the Salon and excited wild enthusiasm. Part of this was due to the subject - a victim of Sulla's proscription returning to Rome to find his wife dead and his house in mourning - in which an allusion was found to the turmoil of the French Revolution. Guerin on this occasion was publicly crowned by the president of the Institute, and went to Rome to study under Joseph-Benoît Suvee. In 1800, unable to remain in Rome on account of his health, he went to Naples, where he painted the Grave of Amyntas. In 1802 Guerin produced Phaedra and Hippolytus (Louvre); in 1810, after his return to Paris, he again achieved a great success with Andromache and Pyrrhus (Louvre); and in the same year also exhibited Cephalus and Aurora (Louvre) and Bonaparte and the Rebels of Cairo (Versailles). These paintings suited the popular taste of the First Empire, being highly melodramatic and pompously dignified. The Restoration brought to Guerin fresh honours; he had received from the first consul in 1803 the cross of the Legion of Honour, and in 1815 Louis XVIII named to the Academie des Beaux-Arts. His style changed to accord with popular taste. In Aeneas Relating to Dido the Disasters of Troy (Louvre), Guerin adopted a more sensuous, picturesque style. Guerin was commissioned to paint for the Madeleine a scene from the history of St Louis, but his health prevented him from accomplishing what he had begun, and in 1822 he accepted the post of director of the French Academy in Rome, which in 1816 he had refused. On returning to Paris in 1828, Guerin, who had previously been made chevalier of the order of St. Michel, was ennobled. He now attempted to complete Pyrrhus and Priam, a work which he had begun at Rome, but in vain; his health had finally broken down, and in the hope of improvement he returned to Italy with Horace Vernet. Shortly after his arrival at Rome Baron Guerin died, on the 6th of July 1833, and was buried in the church of La Trinite de Monti by the side of Claude Lorrain.
