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 muscles of Thorax and shoulders in a lebnden person | la scapigliata | Profile of an old man | Annunciation | Kvinnoportratt |

Merson, Luc-Olivier
French Painter, 1846-1920 French painter and illustrator. He was the son of the painter and art critic Charles-Olivier Merson (1822-1902) and trained initially at the Ecole de Dessin in Paris under Gustave Adolphe Chassevent (1818-1901) and then at the Ecole des Beaux-Arts under Isidore-Alexandre-Augustin Pils. He made his d?but at the Salon in 1867 and won the Grand Prix de Rome in 1869 with the melodramatic work, the Soldier of Marathon (1869; Paris, Ecole N. Sup. B.-A.). As a prizewinner he then spent five years in Italy, where he was impressed and influenced by the works of the Italian Primitives, as is apparent in such works as St Edmund, King and Martyr (1871; Troyes, Mus. B.-A. & Arch?ol.), with its muted colours and rigid composition. In the Salon of 1875 he exhibited Sacrifice for the Country, St Michael, which had been commissioned as a design for a Gobelins tapestry for the Salle des Ev?ques in the Panth?on, Paris. Soon afterwards he was chosen to decorate the Galerie de St Louis in the Palais de Justice, Paris, with scenes from the life of Louis IX. This resulted in two large works, Louis Opening the Doors of the Gaols on his Accession and Louis Condemning Sire Enguerrand de Coucy (both 1877). He also used historical, often religious, subjects for his smaller-scale works, as in St Francis of Assisi Preaching to the Fish (1880; Nantes, Mus. B.-A.).
Woolner, Thomas
1825 - 1892,English sculptor and poet. He ranks with John Henry Foley as the leading sculptor of mid-Victorian England. He trained with William Behnes and in 1842 enrolled as a student at the Royal Academy, London. In 1844 he exhibited at Westminster Hall, London, a life-size plaster group, the Death of Boadicea (destr.), in an unsuccessful attempt to obtain sculptural commissions for the Houses of Parliament. His earliest important surviving work is the statuette of Puck (plaster, 1845-7; C. G. Woolner priv. col.), which was admired by William Holman Hunt and helped to secure Woolner's admission in 1848 to the Pre-Raphaelite Brotherhood. The work's Shakespearean theme and lifelike execution, stressing Puck's humorous malice rather than traditional ideal beauty, made it highly appealing. Although eclipsed by Hunt, John Everett Millais and Dante Gabriel Rossetti, Woolner was an important figure in the Brotherhood. He contributed poetry to its journal, The Germ (1850), and his work was committed to truthfulness to nature more consistently than that of any other Pre-Raphaelite, except for Hunt. This is evident in Woolner's monument to William Wordsworth (marble, 1851; St Oswald, Grasmere, Cumbria).
