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 :. | Last Supper | Study fur the head of a Madchens | St John the Baptist t | Power and ortraits | Annunciation |

Willem Claesz Heda
1594-1682 Dutch Willem Claesz Heda Galleries Dutch painter. He was a still-life painter, who, like Pieter Claesz., is noted for his monochrome breakfast-pieces, which are, however, more opulent than those of Claesz. Heda earliest dated work is a Vanitas (1621; The Hague, Mus. Bredius), which shows a still-life from a high viewpoint, composed of various objects bearing vanitas associations (e.g. a bowl of glowing embers, smoker requisites, an overturned glass and a skull); the colouring is in brownish-grey tones and represents one of the earliest examples of a Dutch monochrome still-life (monochrome refers to the range of tones, rather than of colours). Even in this early work Heda skill at painting textures is evident. A more balanced composition is achieved in another Still-life (1629; The Hague, Mauritshuis) and in the Breakfast Table (1631; Dresden, Gemeldegal. Alte Meister), in both of which the objects, set against a neutral background, are linked by a strong diagonal. The Mauritshuis still-life also gives an early indication of Heda interest in painting the effects of light. In 1631 he became a member of the Haarlem Guild of St Luke (of which he served as deacon on several occasions after 1637).

Georg Friedrich Kersting
1785-1847 German Georg Friedrich Kersting Gallery Kersting was a friend of Caspar David Friedrich, the leading German Romantic painter; his style was influenced by Friedrich, and he shared that artist's romantic attitude, although in a more subjective manner. The two friends went on a walking tour of the Riesengebirge in 1810. During his many hikes with Friedrich, the two painted numerous sketches and observations from nature. He may have painted the staffage in some of Friedrich's early work??such as Morning in the Riesengebirge (1810?C11), a result of their walking tour. He was also a friend of the painter Louise Seidler, who described him as "an altogether splendid and comical fellow" and often served as his model. In 1813 Seidler helped Kersting send a number of his works to Johann Wolfgang von Goethe. Goethe was impressed and recommended that the Grand Duke Charles Augustus purchase his work The Embroiderer. Kersting's most lasting works are his figures in interiors that borrow from seventeenth-century Dutch genre painting. These paintings nevertheless feel contemporary due to the situations depicted and the effect of the artist's personality. The characters are often viewed from the back, as in Friedrich's work, and the scenes provide hints of narrative as the figures engage privately in everyday activities. A number of his works refer to his time in the volunteer corps, the "L??tzow rangers". He drew a full-length self-portrait in 1813, in which he wore the rangers' uniform. The painting On Sentry Duty (1815) depicts three rangers, including the artist Ferdinand Hartmann and the writer Theodor Körner, who fought with Kersting and died in wars against the French.
