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 :. | Kvinnoportratt | Abendmahl | Madonna and Child with a Pomegranate et | The Madonna of the Carnation g | Virgin of the Rocks,completed (mk08) |

Vilhelm Melbye
(14 May 1824 - 6 October 1882) was a Danish marine artist, the brother of Anton Melbye and Fritz Melbye. He worked in London from 1853 to 1866 and, over the course of his career, painted seascapes, coastal and harbor scenes, sailing vessels and topographical subjects in many parts of Europe, especially in the Mediterranean region. Knud Frederik Vilhelm Hannibal Melbye was born on 14 May 1824 in Elsinore, Denmark. He first trained to become a merchant but then turned to painting, studying under his older brother Anton, already an established marine painter, and attending the Royal Danish Academy of Fine Arts from 1844 to 1847. He also took private classes in perspective drawing with Carl Dahl. In 1847, he went on his first journey, to Iceland aboard the corvette Valkyrien, and the following year he traveled to Paris by way of Desseldorf. In Paris he studied with Theodore Gudin (1802 - 1880) before returning to Denmark in 1849. From 1853 to 1866, he lived in London and it was here he changed his name from Vilhelm to Wilhelm. He was appointed Professor at the academy in Copenhagen in 1880 but died in 1882 in Roskilde. He is interred at Assistens Cemetery in Copenhagen.

About 1830 he left his father's firm and supported himself as a drawing-master, working in watercolour before attempting to paint in oil. He exhibited at the Royal Academy from 1825 until failing eyesight afflicted him in 1883. He was elected ARA in 1840 and RA in 1851.
