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 Baptism of Christ | Hl.

Thomas Daniell
1749-1840,was an English landscape painter. He was born at the Chertsey inn, kept by his father, in 1749, and apprenticed to an heraldic painter. Daniell, however, was animated with a love of the romantic and beautiful in architecture and nature. Up to 1784 he painted topographical subjects and flower pieces. By this time his two nephews had come under his influence, the younger, Samuel, being apprenticed to Medland the landscape engraver, and the elder, William, being under his own care. In this year (1784) he embarked for India accompanied by William Daniell, and found at Calcutta ample encouragement. Here he remained ten years, and on returning to London he published his largest work, Oriental Scenery, in six large volumes, not completed till 1808. From 1795 until 1828 he continued to exhibit Eastern subjects, temples, jungle hunts, &c., and at the same time continued the publication of illustrated works. These are Views of Calcutta; Oriental Scenery, 144 plates; Views in Egypt; Excavations at Ellora; Picturesque Voyage to China. These were for the most part executed in aquatint.
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.
