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 :. | Anatomical drawing of the stomach and the intestine | The Madonna of the Carnation (detail) dg | Buste one frontal to seeing man and head of a Lowen | Studies fur the adoration of the Konige | Mona Lisa |

Pieter Claesz
Dutch 1597-1660 Pieter Claesz Locations Dutch painter of German birth. He apparently spent his entire career in Haarlem, where he specialized in still-life paintings. Well over 100 works survive, dating from 1621 to 1660. Most of his pictures are dated and monogrammed PC. Since those initials were shared by the Antwerp still-life painter CLARA PEETERS, several attributions are disputed.

Lebasque, Henri
French Painter, 1865-1937 was born in 1865 at Champign (Maine-et-Loire). He started his education at the Ecole des Beaux-Arts d'Angers, and moved to Paris in 1886. Here, Lebasque started studying under Leon Bonnat, and assisted Humbert with the decorative murals at the Pantheon. Around this time, Lebasque met Camille Pissarro and Auguste Renoir, who later would have a large impact on his work. Lebasque's vision was coloured by his contact with younger painters, especially Edouard Vuillard and Pierre Bonnard, founders of the The Nabis' Group and the Intimists who first favoured the calm and quietude of domestic subject matter. From his first acquaintance with Georges Seurat and Paul Signac, Lebasque learnt the significance of a colour theory which stressed the use of complementary colours in shading. Lebasque was a founding member of the Salon d'Automne in 1903 with his friend Henri Matisse. Two years later a group of artists exhibited there including Georges Rouault, Andre Derain, Edouard Vuillard and Henri Matisse while keeping solid links with other artists such as Gustave Rouault, Raoul Dufy, Louis Valtat and especially Henri Manguin, who made him discover the south of France. His time in South of France would lead to a radical transformation in Lebasque's paintings, changing his colour palette forever. Other travels included the Vendee, Normandie and Brittany, although Lebasque would always prefer the small idyllic villages of the South of France. Lebasque had some commercial success during his lifetime. He worked on the decorations at the theatre of the Champs-Elyses and of the Transatlantique sealiner.
