Leonardo Da Vinci
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.

He is often wrongly referred to as William Clarkson Stanfield. The son of Mary Hoad and James Field Stanfield, an Irish actor and author, he was apprenticed to a heraldic coach painter at the age of 12, but in 1808 he abandoned this and went to sea in a collier. In 1812 he was press-ganged and spent two years on HMS Namur, the guard-ship at Sheerness. After being discharged as the result of an injury in 1814, he joined the merchant navy, sailing to China in the Indiaman Warley in 1815. Soon after his return in 1816 he missed his ship and became a scene painter, first at the Royalty Theatre, Stepney, and then at the Royal Coburg, Lambeth. There he was later joined by David Roberts, who became a lifelong friend, and in 1822 both men were employed as scene painters at the Theatre Royal, Drury Lane. During the next 12 years Stanfield established himself as the most talented scene painter of his day, causing a sensation with some of his huge moving dioramas such as the scenes of Venice in the pantomine Harlequin and Little Thumb (1831). Meanwhile he was building an equally impressive reputation as an easel painter. He first exhibited at the Royal Academy in 1820 and continued to exhibit there regularly until his death. He was elected ARA in 1832 and RA in 1835. Antoine de FavrayFrench, 1706-died circa 1791,French painter. He is not documented until 1738, when he was mentioned as a private pupil of Jean-Fran?ois de Troy (ii), who was then director of the Acad?mie de France in Rome; in 1739 he became an official student at the Acad?mie. Among his student works is a copy (untraced) of Raphael's Fire in the Borgo (Rome, Vatican, Stanza dell'Incendio), which was mentioned by Charles de Brosses and exhibited in Paris in 1741. In 1744, for reasons that are not clear, he left Rome for Malta, remaining there for much of the rest of his career and devoting himself primarily to portraiture and genre painting. His ambition as a history painter, however, was fulfilled to a certain extent as a result of the patronage of two Grand Masters of the Order of the Knights of Malta, Manoel Pinto da Fonseca and Emmanuel de Rohan. His first dated picture executed in Malta is a Portrait of a Maltese Lady (1745; Paris, Louvre). Joseph CaraoudFrench
