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 :. | Profile one with book leaves gekroten of old man | The Annunciation | Madonna and Child with a Pomegranate et | The Annunciation | Drawing of an Infant |

Ferdinand Olivier
German Painter, 1785-1841 Painter, draughtsman and lithographer, brother of Heinrich Olivier. The brothers' mother was a court opera singer in Dessau, and Ferdinand's later interest in the German medieval and Nazarene styles owed much to the intellectual climate at the Anhalt-Dessau court, where Leopold III Frederick Francis, Prince of Anhalt-Dessau, had been the first German prince to introduce the Gothic Revival style. Olivier took up drawing in 1801-2 under the tuition of Carl Wilhelm Kolbe and the engraver Johann Christian Haldenwang (1777-1831). In 1802-3 he accompanied his father to Berlin, where he studied woodcut techniques under Johann Friedrich Gottlieb Unger (1755-1804) and may have attended August Wilhelm Schlegel's lectures on belles-lettres and art. It was here, at the latest, that he discovered Herzensergiessungen eines kunstliebenden Klosterbruders (Berlin, 1797) by Wilhelm Heinrich Wackenroder and Ludwig Tieck, and the latter's Franz Sternbalds Wanderungen (Berlin, 1798), two books of vital significance for the painting of the Romantic era. Having decided to make art their career, Ferdinand and his brother Heinrich spent two years (1804-6) in Dresden, where they copied the works of Ruisdael and Claude Lorrain in the art gallery during the summer months. Ferdinand also took lessons from Jacob Wilhelm Mechau (1745-1808) and Carl Ludwig Kaaz, both painters of idealized landscapes, and he was probably introduced to the work of Philipp Otto Runge and Caspar David Friedrich by Friedrich August von Klinkowström (1778-1835), a friend of Runge. In June 1807 Ferdinand's excellent knowledge of French led to his appointment as embassy secretary in Paris, where Heinrich soon joined him. However, after just a few weeks he gave up his diplomatic career in order to devote himself to a study of the Musee Napoleon, which at that time housed art treasures pillaged from all parts of Europe. Ferdinand and Heinrich jointly produced three paintings for Leopold III Frederick Francis of Anhalt-Dessau: a portrait of Napoleon on Horseback (c.1809; W?rlitz, Schloss), and a Last Supper and Baptism (1809-10; Werlitz, Evangel. Ch.) for the Gothic Revival church in Werlitz. Although these last two were supposed to be copies after the 'old German school', the Olivier brothers in fact used 15th- and 16th-century Dutch and Flemish models to create original compositions. At the end of 1809 they returned to Dessau.
