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 :. | Study for a kneeling Leda | The Virgin of the Rocks | Mona lisa | The Virgin of the Rocks | The Battle of Anghiari |

George Mosson
George Mason IV (December 11, 1725 - October 7, 1792) was an American Patriot, statesman and a delegate from Virginia to the U.S. Constitutional Convention. Along with James Madison, he is called the "Father of the Bill of Rights."[1][2][3][4] For these reasons he is considered one of the "Founding Fathers" of the United States.[5][6] Like anti-federalist Patrick Henry, Mason was a leader of those who pressed for the addition of explicit States rights[7] and individual rights to the U.S. Constitution as a balance to the increased federal powers, and did not sign the document in part because it lacked such a statement. His efforts eventually succeeded in convincing the Federalists to add the first ten amendments of the Constitution. These amendments, collectively known as the Bill of Rights, were based on the earlier Virginia Declaration of Rights, which Mason had drafted in 1776. On the nagging issue of slavery, Mason walked a fine line. Although a slaveholder himself, he found slavery repugnant for a variety of reasons. He wanted to ban further importation of slaves from Africa and prevent slavery from spreading to more states. However, he did not want the new federal government to attempt to ban slavery where it already existed, because he anticipated that such an act would be difficult and controversial.
Giulio Cesare Procaccini
1574-1625 Italian Giulio Cesare Procaccini Gallery Giulio Cesare Procaccini (1574-1625) was an Italian painter and sculptor of the early Baroque era in Milan. Born in Bologna he was son of the Mannerist painter Ercole Procaccini the Elder and brother of Camillo Procaccini and Carlo Antonio Procaccini.

In 1610 he painted six of the Quadroni, large canvases celebrating Saint Charles Borromeo . Among his many altarpieces are the Circumcision now in Galleria Estense, Modena (c.1616) and the Last Supper (1616) for Convent associated with the Basilica della Santissima Annunziata del Vastato in Genoa. He also painted the Scourging of Christ. He worked with Giovanni Battista Crespi (il Cerano) and Pier Francesco Mazzucchelli (il Morazzone) following the directions of Cardinal Federico Borromeo, patron of the arts and cousin of Charles Borromeo. He also painted small religious canvases for rich families, in Milan and in Genoa, where he saw the works of Rubens. His style shows the influence of Bolognese Mannerism and Venetian colorism and marks the beginning of the Baroque.
Joseph Wright
1734-1797 British Joseph Wright Gallery English painter. He painted portraits, landscapes and subjects from literature, but his most original and enduringly celebrated works are a few which reflect the philosophical and technological preoccupations of the later 18th century and are characterized by striking effects of artificial light. He was the first major English painter to work outside the capital all his life: apart from spells in Liverpool (1768-71), Italy (1773-5) and Bath (1775-7), he lived and worked in his native Derby, though exhibiting in London at both the Society of Artists (1765-76, 1791) and the Royal Academy (1778-82, 1789-90, 1794
