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 | The Annunciation | The madonna with the Children | Ceiling decoration yy | The Virgin and Child with St Anne (detail) s |

Jerg Ratgeb
Jerg Ratgeb (also Jörg) (born circa 1480 in Schwäbisch Gmend; died 1526 in Pforzheim) was a German painter and contemporary of Derer. Around the turn of the 15th to 16th century, Ratgeb appears to have spent time in Italy, where he came in contact with Italian Renaissance art and with the recently developed use of perspective in painting. After returning to Germany, he settled in Heilbronn. In 1510, he painted the altar of Saint Barbara in the church of nearby Schwaigern. From 1514 to 1517 he was in Frankfurt am Main, where he painted the walls of the refectory and cloister of the Karmeliterkloster (Carmelite Monastery). The paintings, of which only fragments survive, are the largest wall paintings known to the north of the Alps from that period. His most famous work is the Herrenberg Altarpiece, completed in 1521. It was originally painted for the Stiftskirche (abbey church) of Herrenberg. Today, it is on display in the Staatgalerie at Stuttgart. Ratgeb had developed a distinctive personal expressive style, visibly influenced by artists such as Albrecht Derer, Matthias Grenewald and Hieronymus Bosch.

Copy of the altarpiece in the abbey church at Herrenberg - here depicted when closed Because of his marriage with a serf of the Duke of Werttemberg he lost most of his rights as a citizen of Heilbronn. He moved to Stuttgart, where he became a member of the city council. In that position, he negotiated with the rebelling farmers during the German Peasants' War in 1525. He became part of the military contingent requested by the rebels and was elected councillor and chancellor by the peasants. After the suppression of the rebellion, he was arrested, accused of high treason ("because of the Peasant War and on behalf of Duke Ulrich") and finally executed in Pforzheim in 1526, by being torn apart by four horses.
