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 :. | Flower Studies | The Annunciation d | Detail of Madonna of the Rocks | Adoration of the Magi | Study of a child |

MASTER Bertram
German painter (b. cca. 1345, Minden, d. 1415, Hamburg). was a German International Gothic painter primarily of religious art. His most famous surviving work is the large Grabow Altarpiece (or Petri-Altar) in the Kunsthalle Hamburg, the largest and most important North German painting of the period. There is a 45-scene altarpiece of the Apocalypse, probably by his workshop, in the Victoria and Albert Museum in London. He, or his workshop, also produced sculpture, presumably in wood; in fact in his first years in Hamburg most surviving documentation relates to sculpture, including chandeliers. He is first recorded in Hamburg in 1367, and lived there for the rest of his life, becoming a citizen and Master in 1376, and achieving considerable prosperity. In 1390 he made a will in advance of an intended pilgrimage to Rome, but if he made the journey it had no detectable influence on his art. He was married, but his wife had died by his second will in 1410, when he had a surviving daughter. His style is less emotional than that of his Hamburg near-contemporary Master Francke, but has great charm. Bertram was largely forgotten after the Renaissance until the end of the 19th century

Karl friedrich schinkel
German Painter and Architect, 1781-1841 German architect and painter. As state architect of Prussia (from 1815), he executed many commissions for Frederick William III and other royal family members. He based his work on the revival of various historical styles. His mausoleum for Queen Louise (1810) and the brick and terra-cotta Werdersche Kirche, Berlin (1821 ?C 30), are among the earliest Gothic Revival designs in Europe. Other works include the Greek Revival Schauspielhaus (1818) and Altes Museum (1822 ?C 30), both in Berlin. In 1830 Schinkel became director of the Prussian Office of Public Works; his work as a city planner resulted in new boulevards and squares in Berlin.
