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 :. | Study of the proportion of the head | Study of an apostle | Virgin of the Rocks,completed (mk08) | The Portinari Altarpiece | Our Lady and St Anne |

GOLTZIUS, Hendrick
Dutch Baroque Era Painter and Engraver, 1558-1617 Dutch draughtsman, printmaker, print publisher and painter. He was an important artist of the transitional period between the late 16th century and the early 17th, when the conception of art in the northern Netherlands was gradually changing. Goltzius was initially an exponent of Mannerism, with its strong idealization of subject and form. Together with the other two well-known Dutch Mannerists, Karel van Mander I and Cornelis Cornelisz. van Haarlem, he introduced the complex compositional schemes and exaggeratedly contorted figures of Bartholom?us Spranger to the northern Netherlands. These three artists are also supposed to have established an academy in Haarlem in the mid-1580s, but virtually nothing is known about this project. In 1590 Goltzius travelled to Italy, thereafter abandoning Spranger as a model and developing a late Renaissance style based on a broadly academic and classicizing approach. Later still, his art reflected the growing interest in naturalism that emerged in the northern Netherlands from c. 1600.
Gustaf Fjaestad
Swedish 1868-1948 Swedish painter, printmaker and designer. He trained at the Royal Academy of Arts in Stockholm in 1891-2. Subsequently he studied with Bruno Liljefors and Carl Larsson, assisting them with such decorative schemes as Larsson's fresco at the Nationalmuseum, Stockholm (1896). In 1897 he moved to the Arvika district of V?rmland, where he worked together with his wife, Maja (1873-1961), as painter, craftsman and cabinetmaker, and gathered around him a circle of artists who became known as the Racken group. He first achieved public recognition at the Stockholm Artists Union exhibition in 1898 with some of his snow landscapes, which were an immediate popular success and were often reproduced. He had his first one-man exhibition in Stockholm in 1908,
