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 :. | anna sjalv tredje | Adoration of the Magi (mk08) | Madonna and Child with a Pomegranate et | Madonna with the Yarnwinder | The Madonna of the Carnation (detail) dg |

Bonnard, Pierre
French, 1867-1947 French painter and printmaker. He studied at the Academie Julian and the École des Beaux-Arts (1888 C 89). In the 1890s he became a leading member of the Nabis group and came under the influence of Art Nouveau and Japanese prints. With his friend Édouard Vuillard, he developed the intimate domestic interior scene, a genre known as Intimism, depicting fashionable Parisian life in the years before World War I. He also produced still lifes, self-portraits, seascapes, and large-scale decorative paintings. In 1910 he discovered the south of France and began a series of luminous landscapes of the Mediterranean region. He was fascinated by perspective, which he employed in paintings such as The Dining Room (1913). From the 1920s he specialized in landscapes, interiors, views of gardens, and bathing nudes. He produced illustrations for the celebrated journal Revue blanche and decorative pages for Paul Verlaine's book of poetry Parallelement (1900).
Adriaen van ostade
Dutch Baroque Era Painter, 1610-1685 Painter, draughtsman and etcher. According to Houbraken's rather unreliable biography, he was a pupil concurrently with Adriaen Brouwer of Frans Hals in Haarlem. Hals influenced him very little, whereas Brouwer, who was described as 'known far and wide' as early as 1627, had a decisive influence on the evolution of Adriaen van Ostade's always idiosyncratic portrayal of peasant life. The first documentary mention of Adriaen van Ostade as a painter is in 1632 (Schnackenburg, 1970). Most of his paintings are signed and dated, the earliest firmly dated example being the Peasants Playing Cards
Vicente Lopez
1772-1850 Spanish Vicente Lopez Gallery was an Argentine writer and politician who acted as interim President of Argentina from July 7, 1827 to August 18, 1827. He also wrote the lyrics of the Argentine National Anthem adopted in May 11, 1813. Lopez began his primary studies in the San Francisco School, and later studied in the Real Colegio San Carlos, today the Colegio Nacional de Buenos Aires. He obtained a doctorate of laws in the University of Chuquisaca. He served as a captain in the Patriotic Regiment during the English invasions. After the Argentine victory he composed a poem entitled El triunfo argentino (The Argentine Triumph). He participated in the Cabildo Abierto of May 22, 1810 and supported the formation of the Primera Junta. He had good relations with Manuel Belgrano. When the royalist members of the city government of Buenos Aires were expulsed, he was elected mayor of the city; he was an enemy of the party of Cornelio Saavedra and one of the creators of the First Triumvirate, of which he was the Treasurer. Lopez was a member of the Constituent Assembly of year XIII, representing Buenos Aires. At the request of the Assembly, he wrote the lyrics to a "patriotic march", which eventually became the Argentine National Anthem. It was a military march, whose music was composed by the Catalan Blas Parera; it was approved on March 11, 1813. The first public reading was at a tertulia on May 7 in the house of Mariquita Sanchez de Thompson. It displaced a different march, written by Esteban de Luca, which would have been the hymn if not for the more militaristic Lopez.
