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 :. | Madonna and Child | Female head (La Scapigliata) wt | Annunciation (detail) dg | Madonna in the rock grotto | Study Fur the Trivulzio-monument |

Axel Haig
Swedish etcher and architectural draughtsman , 1835-1921 Swedish printmaker, painter and architect. He studied shipbuilding in Karlskrona from 1850 to 1856. The following year he joined the shipbuilders Lawrence Hill & Co. in Glasgow, but soon left to study architecture in London, where he worked with the English architect Ewan Christian (1814-95) and with William Burges. Under the influence of Burges he became especially interested in Gothic architecture. In the late 1870s he began etching, with the intention of illustrating a book on Scotland's medieval architecture. Haig contributed illustrations to numerous English magazines, including The Architect. (For Haig's drawing of William Burges's competition entry for the Law Courts, London) In 1882 he was awarded a medal for his etchings at the Paris Salon and elected an honorary member of the Swedish Royal Academy.
Paul Delaroche
1797-1856 French Paul Delaroche Locations Painter and sculptor, son of Gregoire-Hippolyte Delaroche. Though he was offered a post in the Bibliotheque Nationale by his uncle, Adrien-Jacques Joly, he was determined to become an artist. As his brother Jules-Hippolyte was then studying history painting with David, his father decided that Paul should take up landscape painting, and in 1816 he entered the Ecole des Beaux-Arts to study under Louis-Etienne Watelet (1780-1866). Having competed unsuccessfully for the Prix de Rome for landscape painting, he left Watelet studio in 1817 and worked for a time with Constant-Joseph Desbordes (1761-1827). In 1818 he entered the studio of Antoine-Jean Gros, where his fellow pupils included Richard Parkes Bonington, Eugene Lami and Camille Roqueplan.
