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 :. | You branching of the Blutgefabe, anatomical figure with heart kidneys and Blutgefaben | Knieened figure in Draperie | Profile of an old man | Adoration of the Magi | Study fur the communion |

Pedro Weingatner
Pedro Weingärtner (Porto Alegre, 1853 e 1929) was an important Academic painter of Brazil, and the first artist born in Rio Grande do Sul to win international praise for his work. Born to a family of German immigrants, he began his artistic career as an amateur, helped by his brother Ineio, who was a lithographer, and possibly also by painter Delfim da Câmara. Anyway, in 1878 he moved to Germany in order to study in the Grossherrzoglisch Badische Kunstschule, in Karlsruhe. There he became a pupil of Ferdinand Keller, Theodor Poeckh and Ernst Hildebrand. In 1880 Keller moved to Berlin, being followed by Weingärtner, who then enrolled in the local Academy. In 1882 he left Germany for France, studying in the Academie Julian under Tony Robert-Fleury and William Adolphe Bouguereau. Wrecked by financial issues, he thought of abandoning his studies, but such situation was reverted by supportive friends, including Baron of Itajube, who got for him a special scholarship from emperor Peter II upon Bouguereau's advice. Then he could further his education in Rome. Thereafter for many years he divided his time between Rio de Janeiro, Porto Alegre and Rome, traveling very often and being celebrated as one of the most important Brazilian painters of his generation. In Rio Grande do Sul he was a star. In 1920 he was back in Porto Alegre, where the remained until death. His fame declined from 1925 on, facing competition from new painters and changing tastes in local art. He devoted all his efforts to a half-Realist half-Romantic approach to Academicism even while such styles were already being severely challenged by Modern tendencies. Major themes in his work were mythological scenes, landscapes and genre paintings focusing mainly immigrants and the gaucho, the folk type of Rio Grande do Sul people.
