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 :. | Mona Lisa (detail) dyk | The Last Supper | Study of the proportion of horses | St John the Baptist t | The Annunciation |

REMBRANDT Harmenszoon van Rijn
Born 1606, Died 1669.One of the great Dutch painters and printmakers of the 17th century, Rembrandt van Rijn is best known for his expressive use of light and shadow (also called chiaroscuro) in his many portraits. Raised in Leiden, he studied with Pieter Lastman (1583-1633) in Amsterdam, then returned to Leiden around 1625 and set up shop as a teacher and portrait artist. Sometime between 1630 and 1632 Rembrandt relocated to Amsterdam, where he spent the rest of his career. Though he had his detractors (some of whom considered him coarse and "low born"), Rembrandt was successful and famous during his lifetime, though he fell on financial hard times in his later years. He was a master printer and produced hundreds of group portraits and historical paintings, including The Anatomy Lesson of Dr. Tulp (1632), The Military Company of Captain Frans Banning Cocq (1642) and Aristotle with a Bust of Homer (1653). His portraits -- including a lifelong trail of intriguing and rather frank self-portraits -- reveal his interest in psychological study and continue to be admired as landmarks in Western art. The Military Company of Captain Frans Banning Cocq is also known as "The Night Watch" because it was thought the painting depicted a nighttime scene. When the painting was cleaned in the 1940s it became obvious that it depicted a daytime scene... He married Saskia van Ulenburgh (also Uylenburgh) in 1634.
Ralph Earl
1751- 1801 Ralph Earl Galleries Ralph Earl was born in either Shrewsbury or Leicester, Massachusetts. By 1774, he was working in New Haven, Connecticut as a portrait painter. In the autumn of 1774, Earl returned to Leicester, Massachusetts to marry his cousin, Sarah Gates. A few months later, their daughter was born; however, Earl left them both with Sarah's parents and returned to New Haven. Like so many of the colonial craftsmen, Earl was self-taught, and for many years was an itinerant painter. In 1775, Earl visited Lexington and Concord, which were the sites of recent battles in the American Revolution. Together with engraver Amos Doolittle, he painted four of his most famous pictures, all battle scenes. Although his father was a colonel in the Revolutionary army, Ralph Earl himself was a Loyalist. In 1778, he left behind his wife and daughter and escaped to England by disguising himself as the servant of British army captain John Money.
