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 Anunciacion | The Annunciation | The master of the Pala Sforzesca attributed | Muscles and bone of leg and Hufte | la scapigliata |

David Octavius Hill
Scottish Painter and Photographer, 1802-1870 was a founding member of the Royal Scottish Academy and its secretary for 40 years. In 1843 he enlisted the help of Robert Adamson (b. 1821, Berunside, Scot. January 1848, St. Andrews), a chemist experienced in photography, in photographing the delegates to the founding convention of the Free Church of Scotland. They used the calotype process, by which an image was developed from a paper negative. In these and other portraits they demonstrated a masterly sense of form and composition and a dramatic use of light and shade. Their five-year partnership resulted in some 3,000 photographs, including many views of Edinburgh and small fishing villages.

Leonardo Alenza Y Nieto
b Madrid, 6 Nov 1807; d Madrid, 30 June 1845 Spanish painter and illustrator. He studied at the Real Academia de S Fernando, Madrid, under Juan Antonio Ribera y Fern?ndez and Jos? de Madrazo y Agudo. He worked independently of court circles and achieved some fame but nevertheless died in such poverty that his burial was paid for by friends. He is often described as the last of the followers of Goya, in whose Caprichos and drawings he found inspiration for the genre scenes for which he became best known. Of these scenes of everyday life and customs the more interesting include The Beating (Madrid, Cas?n Buen Retiro) and Galician with Puppets (c. 1835; Madrid, Cas?n Buen Retiro; see SPAIN, fig. 17). Alenza y Nieto's numerous drawings include the illustrations for Alain-Ren? Lesage's Gil Blas (Madrid, 1840), for an edition of the poems of Francisco de Quevedo published by Castello and for the reviews Semanario pintoresco and El Reflejo. The painting Triumph of David
