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 Virgin and Child with St Anne | Madonna with the carnation | Portrait of Cecilia Gallerani | the last supper | Abendmahl |

Henry Singleton
British Painter, 1766-1839,English painter and illustrator. His father died when he was young, and he was brought up by his uncle, the miniature painter William Singleton (d 1793). In 1782 he entered the Royal Academy Schools in London and in 1784 won a silver medal for a drawing from life, exhibiting at the Royal Academy for the first time the same year. He showed considerable promise and in 1788 won a gold medal for a painting inspired by John Dryden's ode Alexander's Feast that was especially praised by Reynolds. In 1793 Singleton was commissioned by the Royal Academy to paint the group portrait the Royal Academicians Assembled in their Council Chamber (London, RA). He soon became noted for his paintings inspired by the Bible and from literary sources, among them Manto and Tiresias (exh. 1792; London, Tate) from John Dryden's Oedipus, and for his depictions of contemporary historical events, of which the watercolour Design Commemorative of the Abolition of the Slave Trade (1807; London, BM) is an example. Many of his works were engraved in mezzotint and achieved a widespread popularity. He also painted portraits, the writer James Boswell (c. 1795; Edinburgh, N.P.G.) being one of his sitters. Many of Singleton's later works are inclined to be sentimental and were carelessly executed; they were often intended solely for engraving.
