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 :. | Madonna with a Flower | Detail of Madonna of the Rocks | Portrait of Ginerva de'Benci-u | Portrait of Mona Lisa,La Gioconda (mk05) | Study for the Trivulzio Equestrian Monument |

Ambrosius Holbein
1494-1519 German Ambrosius Holbein Gallery Ambrosius Holbein (c. 1494 ?C c. 1519) was a German and Swiss artist in painting, drawing and printmaking. He was the elder brother, by about three years, of Hans Holbein the Younger and like his brother was born in Augsburg (which today is in Bavaria, but then was a free imperial city), a center of art, culture and trade at that time. His father Hans Holbein the Elder was a pioneer and leader in the transformation of German art from the Gothic to the Renaissance style. In his studio both his sons, Ambrosius and Hans, received their first painting lessons as well as the an introduction to the crafts of the goldsmith, jeweller and printmaker. Portrait of a Boy with Blond Hair, 1516, BaselIn 1515 Ambrosius lived in the Swiss town of Stein am Rhein, where he helped a Schaffhausen painter named Thomas Schmid with the murals in the main hall of the St George monastery. The next year saw Ambrosius, as well as his brother Hans, in Basel, where he initially worked as a journeyman in Hans Herbster??s studio. In 1517 he was enrolled in a register of the Basel painters' guild and in 1518 he was naturalized as a citizen there. The Portrait of a Boy with Blond Hair and its companion, the Portrait of a Boy with Brown Hair, are among Ambrosius?? best works of this period. Both are nowadays in the Basel Kunstmuseum. Ambrosius Holbein ranks among the most important of Basel??s illustrators and prominent „small formats?? artists.
