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 :. | Mona Lisa | Landscape in the Arnotal | The Benois Madonna | Holy Hieronymus | Madonna with the Yarnwinder |

Defendente Ferrari
(c. 1480/1485 - c. 1540) was an Italian painter active in Piedmont. Ferrari was born at Chivasso, near Turin, and worked in the workshop of Giovanni Martino Spanzotti. He met considerable success as a painter of polyptychs and altarpieces, characterized by a highly decorative style inspired by Northern Europe masters.
LIEVENS, Jan
Dutch painter (b. 1607, Leiden, d. 1674, Amsterdam) Dutch painter, draughtsman and printmaker. His work has often suffered by comparison with that of Rembrandt, with whom he was closely associated from 1625 to 1631. Yet Lievens's early work is equal to that of Rembrandt, although in later years he turned more towards a somewhat facile rendering of the international Baroque style favoured by his noble patrons, thus never fully realizing his early promise. Nonetheless, he became a renowned portrait painter and draughtsman, and his drawings
WITZ, Konrad
b. cca 1400, Rottweil, d. ca. 1445, Basel. German-born painter from Rottweil in Swabia, active in Switzerland. German painter. One of the great innovators in northern European painting, he turned away from the lyricism of the preceding generation of German painters. His sturdy, monumental figures give a strong impression of their physical presence, gestures are dignified and the colours strong and simple. Even scenes with several figures are strangely undramatic and static. The surface appearance of materials, especially metals and stone, is intensely observed and recorded with an almost naive precision. Powerful cast shadows help to define the spatial relationships between objects. His fresh approach to the natural world reflects that of the Netherlandish painters: the Master of Fl?malle and the van Eycks. He need not, however, have trained in the Netherlands or in Burgundy as knowledge of their style could have been gained in Basle. He remained, however, untouched by the anecdotal quality present in their art,
