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 :. | Madchenkopf with confused hair | The Last Supper | Muscle structure of the thigh | Annunciation (detail) st | The Fotus in the Uterus |

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).
Harriet Backer
Norwegian Painter, 1845-1932 Norwegian painter. In the 1860s and early 1870s she took lessons in drawing and painting in Christiania (now Oslo) and also travelled extensively in Europe with her sister Agathe, a composer and pianist. She copied works in major museums and took occasional art lessons; she later considered this experience to have been of fundamental importance to her artistic development. Little Red Riding Hood (1872; Oslo, N.G.) is impressive in technique, and the early portrait of her sister, Agathe Backer-Grendahl (1874; Holmestrand, Komm.), shows a refined colour scheme. At the age of nearly 30 Backer decided to train professionally as a painter and in 1874 went to Munich. She was never attached to a particular institution, but the influence of her friend the artist Eilif Peterssen was crucial to her development. In Munich she made a thorough study of perspective, which formed a secure basis for her later work.
Jacques Sablet
Jacques Sablet (1749 - 1803) was a Swiss painter. Son of a decorator and gilder from Lausanne, he studied with his father before moving to Paris in 1772; there he worked with Joseph-Marie Vien for three years. When in 1775 Vien was named director of the French Academy in Rome, Sablet accompanied him there. His ambition was to be a history painter, but facing competition from Jacques-Louis David and Pierre Peyron, among others, and lacking solid academic training, he could win no commissions. Instead he turned to portraiture , genre painting, and landscape painting. Most of his genre scenes depicted the city's everyday life and customs of the Campagna. Sablet shared a studio with history painter Hubert Drouais and was friends with Simon Denis. He fled to Florence in 1793 with the rise of anti-French sentiment in the Papal States, but perhaps because of the competition he would face there from Louis Gauffier he soon returned to Paris.
