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 :. | The madonna with the Children | The Annunciation | Anatomical studies of the basin of the Steibeins and the lower Gliedmaben of a woman and study of the rotation of the arms | Leda h | The Madonna of the Carnation g |

Constantin Hansen
Danish 1804-1880 Constantin Hansen Galleries Danish painter. In 1816 he entered the Kongelige Akademi for de Sk?nne Kunster, Copenhagen, intending to study architecture; however he later became attracted to painting and worked under C. W. Eckersberg from 1828 to 1833. Around the middle of the 1820s he started developing an individual style of portraiture, which had matured by 1830. He often used his sisters and friends as models; using simple costumes, poses and compositions, he managed to endow his pictures with the intimacy and warmth that mark the Danish Golden Age. The Artist's Sisters Signe and Henriette Reading a Book (1826; Copenhagen, Stat. Mus. Kst) is a fine example of his combination of natural observation with Neo-classical idealization. Under Eckersberg, who encouraged both, he strengthened his natural flair for painting serene architectural views of Copenhagen.
James Duffield Harding
English Painter, ca.1797-1863 English painter, engraver and writer. He received his first lessons in painting from his father, J. Harding (d 1846), who was a pupil of Paul Sandby. By 1807 the family had moved to Greenwich where Harding spent much of his time drawing and painting in Greenwich Park. In 1811 at the age of 14 he exhibited for the first time at the Royal Academy. He had lessons in watercolour painting from Samuel Prout and in 1816 he won the Society of Arts silver medal for landscape painting.
Caspar David Friedrich
1774-1840 Caspar David Friedrich Locations German painter, studied art at Copenhagen, and in 1798 settled in Dresden. Friedrich painted chiefly landscapes and seascapes, with and without figures, architectural pictures, including a few of Dresden, and some religious subjects. Religious feeling and symbolism permeate his œuvre, of which the seascape with figures, Die Lebensstufen, is a characteristic example. He possessed considerable power to convey mood in landscape. Almost forgotten in the 19th c. and early 20th c., interest in his work increased considerably in the mid-20th c. He is hardly represented in Britain, but an exhibition of 112 of his pictures at the Tate Gallery in 1972 attracted much attention. F. G. Kersting was a friend of Friedrich.
