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 :. | Portrait of a Lady at the Court of Milan (san05) | Reverse side of the portrait of Ginevra de' Benci | Study of a child | Portrait of a Musician | Study for a kneeling Leda |

Johann Georg von Dillis
(born Gmain, December 26, 1759 - died Munich, September 28, 1841) was a German painter. Son of a gamekeeper and forester, he was educated in Munich with support from the prince-elector of Bavaria. Initially he was trained for the priesthood, but by 1786 his real interest, art, was beginning to be developed, and he taught drawing both at court and to private families. In 1790 he was appointed inspector of the Hofgarten Galerie, the princely collection. He continued in a curatorial role for the Bavarian court for much of the rest of his career; this allowed him some freedom to travel and expand his knowledge of European art. In 1792 he traveled to Dresden, Prague, and Vienna, and in 1794 he made his first trip to Italy, where he made watercolor studies from nature. A further trip to Italy followed in 1805, and brought him to Rome, where he met Pierre-Henri de Valenciennes, who introduced him to the idea of painting in open air. He studied the work of Simon Denis and Joseph Mallaord William Turner, and encountered Washington Allston. The next year, in Paris, he saw oil sketches by Jean-Joseph-Xavier Bidauld, and with Ludwig, the crown prince visited the Musee Napoleon; he would later advise the prince on collecting and other matters artistic, remaining in this capacity for the rest of his life. He also made several trips to Italy to purchase art for the royal collection. In 1816 he was made responsible for packing and returning to Munich from Paris art stolen from Bavaria by Napoleon. In the fall of 1817 he and Ludwig traveled to Sicily before spending four months in Rome. Dillis helped to shape the collections of the Alte Pinakothek, which opened in 1836. He died in Munich in 1841.
