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 Adoration of the Magi | Madonna with the Yarnwinder (detail) dft | Mona Lisa | Salai as John the Baptist | The master of the Pala Sforzesca attributed |

Joseph Stieler
German Painter, 1781-1858,German painter. In 1798 he studied under Christoph Fesel (1737-1805) in Werzburg and in 1800 with Heinrich Feger in Vienna, where his style was strongly influenced by English portraiture. After he studied in Paris (1807-8) with Fran?ois G?rard the influence of Neo-classicism became apparent in his work. He visited Italy in 1809, 1810 and 1812 to do commissioned portraits for various patrons, among them Prince Eugene de Beauharnais (1809; Munich, Bayer. Nmus.) and Joachim Murat, King of Naples (reg 1808-15). In 1812 he went to Munich where he did work for middle-class clients, the nobility and the royal family of Bavaria (e.g. the portrait of Maximilian I Joseph, 1816; Ellingen, Schloss). In 1820 he was appointed court painter to Ludwig I, King of Bavaria (reg 1825-48), and painted several portraits of him. In 1823 he helped co-found the Kunstverein in Munich. He was one of the most important portrait painters in the Neo-classical style, specializing particularly in studies of women, as seen in the 36 portraits commissioned by Ludwig I for the Schenheitsgalerie (1827-42; Munich, Schloss Nymphenburg). In his portraits for the middle classes and for the court he devised certain peculiarities of form. He painted various members of the royal houses of Austria, Prussia and Sweden, as well as members of the nobility in the duchies of Saxe-Altenberg, Saxe-Coburg and Hesse. His sitters also included some of the most important figures in the political and intellectual life of Germany in the first half of the 19th century. He painted the pendant portraits of Franz Brentano and Antonie Brentano (both 1808; Winkel, Brentanohaus), Johann Wolfgang von Goethe (1828; Munich, Neue Pin.) and Ludwig Tieck (1838; Berlin, Schloss Charlottenburg), the geographer and botanist Alexander von Humboldt (1843; Potsdam, Schloss Charlottenhof) and the musician Ludwig van Beethoven (Bonn, Beethoven-Haus). After 1845 the classical elements in his paintings were sometimes combined with an application of colour typical of plein-air studies. He also painted genre pictures and religious scenes.
