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 :. | Annunciation (detail) fg47 | Annunciation (detail) sg77 | Mona Lisa (mk45) | Leda and the Swan | Virgin of the Rocks |

Thomas Sully
1783-1872 Thomas Sully Galleries Sully became a professional painter at age 18 in 1801. He studied face-painting under Gilbert Stuart in Boston for three weeks. After some time in Virginia with this brother, Sully moved to New York, after which he moved to Philadelphia in 1806, where he resided for the remainder of his life. In 1809 he traveled to London for nine months of study under Benjamin West. Sully's 1824 portraits of John Quincy Adams, who became President within the year, and then the Marquis de Lafayette appear to have brought him to the forefront of his day. (His Adams portrait may be seen in the National Gallery of Art, Washington.) Many famous Americans of the day had their portraits painted by him. In 1837-1838 he was in London to paint Queen Victoria at the request of Philadelphia's St. George's Society. His daughter Blanche assisted him as the Queen's "stand-in", modeling the Queen's costume when she was not available. One of Sully's portraits of Thomas Jefferson is owned by the Jefferson Literary and Debating Society at the University of Virginia and hangs in that school's Rotunda. Another Jefferson portrait, this one head-to-toe, hangs at West Point, as is his portrait of Alexander Macomb (American general). Sully's own index indicates that he produced 2631 paintings from 1801, most of which are currently in the United States. His style resembles that of Thomas Lawrence. Though best known as a portrait painter, Sully also made historical pieces and landscapes. An example of the former is the 1819 Passage of the Delaware, now on display at the Museum of Fine Arts, Boston.
Constance Marie Charpentier
(born 1767 Paris, France - August 3, 1849 France) was a French painter. She specialized in sentimental genre scenes and portraits, mainly children and women. She was also known as Constance Marie Bondelu. She studied under Jacques-Louis David and Francois Gerard. In 1788 she received a 'Prix d'Encouragement.' From 1795 to 1819 she exhibited at the Salon where she received a gold medal.
Cristofano Allori
Italian Baroque Era Painter, 1577-1621 was an Italian portrait painter of the late Florentine Mannerist school. Allori was born at Florence and received his first lessons in painting from his father, Alessandro Allori, but becoming dissatisfied with the hard anatomical drawing and cold coloring of the latter, he entered the studio of Gregorio Pagani (1558-1605) who was one of the leaders of the late Florentine school, which sought to unite the rich coloring of the Venetians with the Florentine attention to drawing. Allori also appears to have worked under Cigoli. His pictures are distinguished by their close adherence to nature and the delicacy and technical perfection of their execution. His technical skill is shown by the fact that several copies he made of Correggio's works were thought to be duplicates by Correggio himself. His extreme fastidiousness limited the number of his works. Several specimens are to be seen at Florence and elsewhere. The finest of his works is his Judith with the Head of Holofernes. It exists in two copies in the Pitti Palace in Florence and in the Queen's Gallery in London.
