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 :. | The Virgin and the Nino with Holy Ana | Hi Hieronymus | Head of a girl | Anatomical studies of the basin of the Steibeins and the lower Gliedmaben of a woman and study of the rotation of the arms | Study fur the Sforza monument |

Johan Vilhelm Gertner
(10 March 1818 - 28 March 1871) was a Danish painter, best known for his portraiture. One of the last students of Christoffer Wilhelm Eckersberg, who was known as the father of the Golden Age of Danish Painting, Gertner belonged to the tail end of the Golden Age, a period during which Danish art moved towards a more realistic style, relying on inspiration both from French Realism and emerging photographic techniques. Gertner was born on 10 March 1818 to a craftsman at the Holmen naval base. He attended the Royal Danish Academy of Fine Arts from 1831 to 1837 where he was one of Christoffer Wilhelm Eckersberg, known as the farther of Goldn Age of Danish Painting. Eckersberg taught him a naturalistic approach to painting, but Gertner went much further with inspiration from French art and the emerging techniques of photography. His virtuosity in producing almost photographically precise portraits impressed many; in particular, his ability to reproduce textures and materials e crisp silk dresses, lustrous medals and jewellery, dark mahogany furniture, silky wallpapers, and soft carpets e won him much acclaim. Others, such as the influential art historian and critic Niels Lauritz Høyen, who opposed any foreign influence on Danish painting, disapproved of his style, preferring more sincere and sensitive portrayals. He was a professor at the Academy from 1858.
Juan Sanchez-Cotan
Spanish 1561-1627 S??nchez Cot??n was born in the town of Orgaz, near Toledo. He was a friend and perhaps pupil of Blas de Prado, an artist famous for his still lifes whose mannerist style with touches of realism, the disciple developed further. Cot??n began by painting altar pieces and religious works. For approximately twenty years, he pursued a successful career in Toledo as an artist, patronized by the city??s aristocracy, painting religious scenes, portraits and still lifes. These paintings found a receptive audience among the educated intellectuals of Toledo society. S??nchez Cot??n executed his notable still lifes around the turn of the seventeenth century, before the end of his secular life. An example (seen above) is Quince, Cabbage, Melon and Cucumber (1602, in the San Diego Museum of Art). On August 10, 1603, Juan Sanchez Cotan, then in his forties, closed up his workshop at Toledo to renounce the world and enter the Carthusian monastery Santa Maria de El Paular. He continued his career painting religious works with singular mysticism. In 1612 he was sent to the Granada Charterhouse, he decided to become a monk, and in the following year he entered the Carthusian monastery at Granada as a laybrother. The reasons for this are not clear, though such action was not unusual in Cot??n??s day. Cotan was a prolific religious painter whose work, carried out exclusively for his monastery, reached its peak about 1617 in the cycle of eight great narrative paintings which he painted for the cloister of the Granada Monastery. These depict the foundation of the order of St. Bruno, and the prosecution of the monks in England by the Protestants. Although the painter??s religious works have an archaic air, they also reveal a keen interest in the treatment of light and volumes, and in some respect are comparable with certain works by the Italian Luca Cambiaso whom Cotan knew at the Escorial. While Cotan's religious works are unexceptional, as a still-life painter he ranks with the great names of European painting. In spite of his retreat from the world, Cotan??s influence remained strong. His concern with the relationships among objects and with achieving the illusion of reality through the use of light and shadow was a major influence on the work of later Spanish painters such as Juan van der Hamen, Felipe Ramirez, the brothers Vincenzo and Bartolomeo Carducci and, notably, Francisco de Zurbaran. Sanchez Cotan ended his days universally loved and regarded as a saint. He died in 1627 in Granada.
NAIVEU, Matthijs
Dutch painter (1647-1726) Dutch painter. He was the son of a wine merchant from Rotterdam and began his training with Abraham Toorenvliet (c. 1620-92), a glass painter and drawing master in Leiden. From 1667 to 1669 Naiveu was apprenticed to the Leiden 'Fine' painter Gerrit Dou, who received 100 guilders a year (an exceptionally high sum) for instructing Naiveu. In 1671 Naiveu entered the Leiden Guild of St Luke, of which he became the head in 1677 and again in 1678, the year in which he moved to Amsterdam, where he was later appointed hop inspector. This work did not prevent him producing a considerable number of paintings; the earliest known work by Naiveu is dated 1668, the latest 1721.
