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 :. | Portrait of Cecilia Gallarani | The Virgin and Child with Anne (mk05) | Detail of Madonna of the Rocks | Adoration of the Magi | The Annunciation |

MASTER of Heiligenkreuz
Austrian Northern Renaissance Painter, 15th Century,was an Austrian painter active at the beginning of the fifteenth century; a tentative lifespan of 1395 to 1430 has been put forth, but this appears highly conjectural. His name is taken from a diptych that once belonged to the Cistercian Abbey of Heiligenkreuz, located in southeastern Austria near the present-day border with Hungary. The left panel depicts the Annunciation on the obverse; the reverse is a depiction of the Madonna and Child. The right panel depicts the Mystical Marriage of Saint Catherine, with Saint Dorothy on its reverse. Details of costume and iconography combine with associations with the International Style to indicate a date of around the first decade of the fifteenth century. It was initially proposed, by Betty Kurth in 1922, that the artist was French and had some association with the court in Paris. Other writers have disagreed, and various nationalities including French, Austrian, German, or Bohemian have been posited for the Master. Some have further suggested that he was an itinerant court artist, trained in France but active in Austria. Various clues have been used in an attempt to describe his nationality. These include his use of finely-worked gold decoration, in which some have seen a link to Franco-Burgundian goldsmith's work of the late fourteenth century. Others, instead, see it as a link to the school of panel painting then active at the court in Prague. Consequently, it seems highly unlikely that the artist's nationality will be conclusively established.
