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 :. | The Baptism of Christ (detail) sg | Madonna and Child | Portrait of Cecilia Gallerani | Grotesque profile of a man | Benois Madonna |

Philip James de Loutherbourg
1740-1812 French (Resident in UK) Philip James de Loutherbourg Gallery Philip James de Loutherbourg, also seen as Philippe-Jacques and Philipp Jakob and with the appellation the Younger (31 October 1740 ?C 11 March 1812) was an English artist of French origin. He was born in Strasbourg, where his father, the representative of a Polish family, practised miniature painting; but he spent the greater part of his life in London, where he was naturalized, and exerted a considerable influence on the scenery of the English stage, as well as on the artists of the following generation. De Loutherbourg was intended for the Lutheran ministry, and was educated at the University of Strasbourg. As the calling, however, was foreign to his nature, he insisted on being a painter, and placed himself under Charles-Andr?? van Loo in Paris. The result was an immediate and precocious development of his powers, and he became a figure in the fashionable society of that day. In 1767 he was elected into the French Academy below the age required by the law of the institution, and painted landscapes, sea storms, battles, all of which had a celebrity above those of the specialists then working in Paris. His debut was made by the exhibition of twelve pictures, including Storm at Sunset, Night, Morning after Rain. He is next found travelling in Switzerland, Germany and Italy, distinguishing himself as much by mechanical inventions as by painting. One of these, showing quite new effects produced in a model theatre, was the wonder of the day. The exhibition of lights behind canvas representing the moon and stars, the illusory appearance of running water produced by clear blue sheets of metal and gauze, with loose threads of silver, and so on, were his devices. In 1771 he came to London, and was employed by David Garrick, who offered him £500 a year to apply his inventions to Drury Lane, and to superintend the scene-painting, which he did with complete success, making a new era in the adjuncts of the stage. Garrick's own piece, the Christmas Tale, and the pantomime, 1781-1782, introduced the novelties to the public, and the delight not only of the masses, but of Reynolds and the artists, was unbounded. The green trees gradually became russet, the moon rose and lit the edges of passing clouds, and all the world was captivated by effects we now take little notice of. A still greater triumph awaited him on his opening an entertainment called the Eidophusikon, which showed the rise, progress and result of a storm at sea that which destroyed the great Indiaman, the Halsewell,and the Fallen Angels raising the Palace of Pandemonium. De Loutherbourg has been called the inventor of the panorama, but this honor does not belong to him, although it first appeared about the same time as the eidophusicon. The first panorama was painted and exhibited by Scottish painter Robert Barker.
