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 :. | Interior view of the Schadels | The Last Supper | Gekrose of the intestine and its Gefabsystems | Annunciation (detail) ey79 | Battle of Anghiari |

Jonathan Eastman Johnson
1824-1906 Jonathan Eastman Johnson Galleries Eastman Johnson (July 29, 1824 - April 5, 1906) was an American painter, and Co-Founder of the Metropolitan Museum of Art, New York City, with his name inscribed at its entrance. Best known for his genre paintings, paintings of scenes from everyday life, and his portraits both of everyday people, he also painted portraits of prominent Americans such as Abraham Lincoln, Nathaniel Hawthorne, Ralph Waldo Emerson, and Henry Wadsworth Longfellow. His later works often show the influence of the 17th century Dutch masters whom he studied while living in The Hague, and he was even known as The American Rembrandt in his day. Johnson's style is largely realistic in both subject matter and in execution. His original photorealistic charcoal sketches were not strongly influenced by period artists, but are informed more by his lithography training. Later works show influence by the 17th century Dutch and Flemish masters, and also by Jean François Millet. Echoes of Millet's The Gleaners can be seen in Johnson's The Cranberry Harvest, Island of Nantucket although the emotional tone of the work is far different. His careful portrayal of individuals rather than stereotypes enhances the realism of his paintings. Ojibwe artist Carl Gawboy notes that the faces in the 1857 portraits of Ojibwe people by Johnson are recognizable in people in the Ojibwe community today. Some of his paintings such as Ojibwe Wigwam at Grand Portage display near photorealism long before the photorealism movement but in keeping with the American tradition of realism that can be seen in the works of Charles Willson Peale whose painting The Stairway Group is said to have fooled George Washington. His careful attention to light sources contributes to the realism. Portraits Girl and Pets and The Boy Lincoln make use of single light sources in a manner that echoes the 17th Century Dutch Masters.
Walter Crane,RWS
1845-1915 English painter, illustrator, designer, writer and teacher. He showed artistic inclinations as a boy and was encouraged to draw by his father, the portrait painter and miniaturist Thomas Crane (1808-59). A series of illustrations to Tennyson's The Lady of Shalott (Cambridge, MA, Harvard U., Houghton Lib.) was shown first to Ruskin, who praised the use of colour, and then to the engraver William James Linton, to whom Crane was apprenticed in 1859. From 1859 to 1862 Crane learnt a technique of exact and economical draughtsmanship on woodblocks. His early illustrative works included vignette wood-engravings for John R. Capel Wise's The New Forest: Its History and its Scenery (1862).
