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 :. | Last Supper | The Annunciation | Mona Lisa (detail) r y | La belle Ferronire dg | The Virgin and Child with St Anne ey |

Franz Horny
German, 1798-1824,German painter. He received his first instruction in art from his father, Conrad Horny (1764-1807), a painter and copperplate engraver, who taught at the Zeichenschule in Weimar. He attended this school from 1806 to 1816, training primarily as a painter of landscapes. In 1816, his patron Baron Carl Friedrich von Rumohr, a friend of his father, enabled him to travel to Italy. In Rome Horny became a student of Joseph Anton Koch, who introduced him to landscape composition in the classically heroic style. Through eager study, both from nature and from live models, Horny's skills developed swiftly, especially in his work in pen and watercolour (e.g. View of Olevano with Shepherds and a Hermit, 1817; Dresden, Kupferstichkab.). Horny was soon, however, drawn into the circle of the Lukasbr?der: Peter Joseph Cornelius persuaded him to participate in the major fresco project for the Casino Massimo in Rome. Horny completed a large number of pen and watercolour drawings (e.g. Weimar, Schlossmus.) depicting flowers, fruit and birds, and intended as wreaths and festoons to frame Cornelius's historical scenes from Dante's Paradiso. When Cornelius was recalled to Munich in 1818, however, this fresco was not carried out and Horny's designs were therefore not used. In the same year, Horny developed tuberculosis and moved to Olevano for his health. The rugged beauty of the Sabine Hills and their picturesque towns drew him back to the depiction of landscape. His drawings, combining Koch's classically heroic outlook with the poetic sensibility of the Lukasbr?der, often convey the impression of an earthly paradise, as in Italian Country Life (c. 1820; L?beck, St Annen-Mus.).
