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 :. | Hi Hieronymus | Madchenkopf with confused hair | The Anunciacion | The Virgin and Child with St Anne | Self Portrait |

Italian Early Renaissance Painter, ca.1445-1530
Artist Adolphe Joseph Thomas Monticelli
(October 14, 1824 - June 29, 1886) was a French painter of the generation preceding the Impressionists. Monticelli was born in Marseille in humble circumstances. He attended the École Municipale de Dessin in Marseille from 1842 to 1846, and continued his artistic training in Paris, where he studied under Paul Delaroche at the École des Beaux-Arts. In Paris he made copies after the Old Masters in the Louvre, and admired the oil sketches of Eugene Delacroix. In 1855 he met Narcisse Diaz, a member of the Barbizon school, and the two often painted together in the Fontainebleau Forest. Monticelli frequently adopted Diaz's practice of introducing nudes or elegantly costumed figures into his landscapes. He developed a highly individual Romantic style of painting, in which richly colored, dappled, textured and glazed surfaces produce a scintillating effect. He painted courtly subjects inspired by Antoine Watteau; he also painted still lives, portraits, and Orientalist subjects that owe much to the example of Delacroix. After 1870, Monticelli returned to Marseille, where he would live in poverty despite a prolific output, selling his paintings for small sums. An unworldly man, he dedicated himself singlemindedly to his art. The young Paul Cezanne had befriended Monticelli in the 1860s, and the influence of the older painter's work can be seen in Cezanne's work of that decade. Between 1878 and 1884 the two artists often painted landscapes together, once spending a month roaming the Aix countryside. Although Monticelli experimented briefly around 1870 with a treatment of light reflecting the discoveries of the Impressionists, he found the objectivity of this approach uncongenial. Confronted with criticism of his style of painting Monticelli himself remarked, "I paint for thirty years from now". The work of this instinctive painter reached its greatest spontaneity in the decade before his death in 1886.
