LEONARDO da Vinci
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.

de Figueiredo e Melo (Areia, Brazil, 29 April 1843 - Florence, Italy, 7 October 1905) was one of the most important academic painters of Brazil. He was also a writer and a teacher.
He moved to Rio de Janeiro in 1854, where he was granted a scholarship to study in the Academia Imperial de Belas Artes (Imperial Academy of Fine Arts). Later he furthered his studies in Europe, at the École des Beaux-Arts in Paris, being a pupil of Jean-Auguste-Dominique Ingres, Hippolyte Flandrin and Carle-Horace Vernet, winning much praise for his paintings, and achieving the Doctorate in Sciences at the University of Brussels, in 1868.
Returning to Brazil, he produced a great series of masterpieces, including one of the most well known works of art in Brazil: Independence or Death!, depicting the moment when Prince Peter declared the country independent from Portugal, a work that has illustrated History books for elementary schools in Brazil for decades. Living mostly in Florence, Italy but traveling extensively back and forth from Rio de Janeiro, Pedro Am??rico managed to work also as a lecturer and an art historian.
He married Carlota de Ara??jo Porto-alegre (1844?C1918), daughter of painter and diplomat Manuel de Ara??jo Porto-alegre, and they had children. Knighted by the German Crown he was also Great Knight of the Order of the Holy Sepulchre. With the proclamation of the Republic in Brazil in 1889, he was elected a deputy of the National Assembly.
French Painter , (1789-1851)DAVID, Gerard
Netherlandish Northern Renaissance Painter, ca.1460-1523
Netherlandish painter. He is known as the last of the 'Flemish Primitives'. Although born in the northern Netherlands, he moved to Bruges as a young man, and most of his work expresses the impassive, unmannered, microscopically realistic approach peculiar to south Netherlandish art in the time of Jan van Eyck. David was skilled at synthesizing the art of several important south Netherlandish predecessors, adapting, for instance, the compositions of van Eyck and the technique of Hugo van der Goes. He was also influenced by Hans Memling,
