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 :. | Adoration of the Magi (mk08) | virgin and child with st.anne | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | Equestrian monument | Adoration of the Magi |

Theodor Kalide
1801 Konigshutte-1863 Gleiwitz,German sculptor. At the age of 15 he was apprenticed at the K?nigliche Eisengiesserei in Gleiwitz, where he soon began sculpting cast-iron plaques. In 1819 Johann Gottfried Schadow summoned him to Berlin, where he was instructed in chasing by Cou? and worked in the Berlin Eisengiesserei. In 1821 he transferred to the studio of Christian Daniel Rauch. Following Rauch's example and under his influence, Kalide produced such large animal sculptures as the Resting Lion and the Sleeping Lion (several casts, e.g. zinc, 1824; Berlin, Schloss Kleinglienicke). From 1826 to 1830 Kalide worked on equestrian statuettes, including those of Frederick William II (zinc), after the model by Emanuel Bardou (1744-1818), and Frederick William III (e.g. cast iron; both Berlin, Schloss Charlottenburg, Schinkel-Pav.). In 1830 he became a member of the Berlin Akademie. His most popular works included the life-size bronze group Boy with a Swan (1836), which was installed on the Pfaueninsel in Berlin as a fountain (several casts, all untraced). Kalide achieved wide recognition and aroused violent controversy with his almost life-size marble figure Bacchante on the Panther (1848; Berlin, Schinkelmus., badly damaged). This work transgressed the accepted boundaries of classical art, above all in the figure's provocative pose, and was perceived as shocking. In its uninhibited sensuality and its blending of the human and the animal, it offended the conservative Berlin public, and consequently Kalide received few new commissions. He had no success with competition designs and became increasingly embittered. He spent his last years at Gleiwitz, where he died.

Vladimir Tatlin
1885-1953,Ukrainian sculptor and painter. After a visit to Paris (1914), he became the leader of a group of Moscow artists who sought to apply engineering techniques to sculpture construction, a movement that developed into Constructivism. He pioneered the use of iron, glass, wood, and wire in nonrepresentational constructions. His Monument to the Third International, commissioned by the Soviet government, was one of the first buildings conceived entirely in abstract terms and was intended to be, at more than 1,300 ft (400 m), the world's tallest structure. A model was exhibited at the 1920 Soviet Congress, but the government disapproved of nonfigurative art and it was never built. After 1933 Tatlin worked largely as a stage designer.
