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 Refectory with the Last Supper after restoration g | Lorenzo de Medici between Antonio Pucci and Francesco Sassetti, with Giulio de Medici, fresco by Ghirlandaio | The Annunciation | The Madonna of the Carnation (detail) sg | Battle of Anghiari |

ALBERTINELLI Mariotto
Italian Early Renaissance Painter, 1474-1515 Italian painter. Albertinelli's contribution to the Florentine High Renaissance was inspired by the work of FRA BARTOLOMMEO, and the two artists worked together in a partnership, their paintings appearing to be the product of a single hand. Albertinelli, however, always retained artistic independence, as is revealed in certain paintings that are eccentrically archaic and in others that show a preference for conventions more typical of the early Renaissance.
Gustave Courbet
1819-1877 French Gustave Courbet Locations was a French painter whose powerful pictures of peasants and scenes of everyday life established him as the leading figure of the realist movement of the mid-19th century. Gustave Courbet was born at Ornans on June 10, 1819. He appears to have inherited his vigorous temperament from his father, a landowner and prominent personality in the Franche-Comte region. At the age of 18 Gustave went to the College Royal at Besancon. There he openly expressed his dissatisfaction with the traditional classical subjects he was obliged to study, going so far as to lead a revolt among the students. In 1838 he was enrolled as an externe and could simultaneously attend the classes of Charles Flajoulot, director of the ecole des Beaux-Arts. At the college in Besançon, Courbet became fast friends with Max Buchon, whose Essais Poetiques (1839) he illustrated with four lithographs. In 1840 Courbet went to Paris to study law, but he decided to become a painter and spent much time copying in the Louvre. In 1844 his Self-Portrait with Black Dog was exhibited at the Salon. The following year he submitted five pictures; only one, Le Guitarrero, was accepted. After a complete rejection in 1847, the Liberal Jury of 1848 accepted all 10 of his entries, and the critic Champfleury, who was to become Courbet first staunch apologist, highly praised the Walpurgis Night.
NATTIER, Jean-Marc
French Rococo Era Painter, 1685-1766 Brother of Jean-Baptiste Nattier. As well as being taught by his father, he trained with his godfather, Jean Jouvenet, and attended the drawing classes of the Acad?mie Royale, where in 1700 he won the Premier Prix de Dessin. From around 1703 he worked on La Galerie du Palais du Luxembourg. The experience of copying the work of Rubens does not, however, seem to have had a liberating effect on his draughtsmanship, which was described by the 18th-century collector Pierre-Jean Mariette as 'cold'. Nattier was commissioned to make further drawings for engravers in the early part of his career, including those after Hyacinthe Rigaud's famous state portrait of Louis XIV (1701; Paris, Louvre) in 1710, which indicates that he had established a reputation while he was still quite young. Although he was offered a place at the Acad?mie de France in Rome on the recommendation of Jouvenet, Nattier preferred to remain in Paris and further his career. In 1717 he nevertheless made a trip to Holland, where he painted portraits of Peter the Great and the Empress Catherine (St Petersburg, Hermitage).
