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 :. | Madchenkopf with confused hair | The Last Supper | Mona Lisa | Hl.

Joseph Heintz the Elder
the Elder (Basle, 11 June 1564 - near Prague, Bohemia, October 1609) was a Swiss painter, draftsman and architect. He appears to have been a pupil of Hans Bock, and to have educated himself by diligent practice in copying the works of Hans Holbein the younger. Between 1585 and 1587 he lived in Rome, registering himself a pupil; to Hans von Aachen. He next settled in Bohemia in 1591, and was at once appointed court painter to Rudolf II, but he remained in Prague for two years only, as in 1593 he was commissioned to make some copies from the antique for the emperor, and for that purpose went to Rome, where he spent some years. In 1604 we hear of him in Augsburg, and from the time we know little of his history, until his decease is recorded in a village outside of Prague. Heintz's paintings included religious images, portraits, and, following the emperor's taste, erotic mythological themes. They were at one time in high demand, but later on suffered an eclipse. Among them are a family portrait in Berne and that of Rudolf II in Vienna. He was constantly investigating subtle questions of light, and almost all of his landscapes show the interest he took in this technical matter. A notable work by him is the Rape of Proserpine, which hangs in the Dresden Gallery, and was engraved by Lukas Kilian; in the same gallery are two other works, Lot and His Daughters and Ecce Homo. Finally there is his portrait of Constance of Austria. He had a son, who bore the same name, and who painted a few religious pictures; several of these works hitherto attributed to the son are now believed to be late productions by the father.
