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 :. | Annunciation (detail) fg47 | The Virgin and Child with St Anne (detail) s | The organs of the woman | Mona Lisa | Madchenkopf with confused hair |

George Hayter
1792 - 1871 English painter and printmaker. He was the son of Charles Hayter (1761-1835), miniature painter, author of manuals for art instruction and Professor of Perspective and Drawing to Princess Charlotte. In 1808 George entered the Royal Academy Schools, and in 1815 was appointed Painter of Miniatures and Portraits by Princess Charlotte. Hayter was awarded the British Institution's premium for history painting for the Prophet Ezra (1815; Downton Castle, Heref. & Worcs), purchased by Richard Payne Knight. Encouraged by his patron, John Russell, 6th Duke of Bedford, he travelled to Italy to study in 1816, gaining election as an honorary member of the Accademia di S Luca in Florence. Returning to London in 1818, Hayter practised as a portrait painter in oils and history painter and occasionally acted as an art dealer. Dubbed 'The Phoenix' by William Beckford, Hayter showed a pomposity that irritated his fellow artists, but he mixed freely with many aristocratic families.

AUGUSTIN, Jacques-Jean-Baptiste
French miniaturist (b. 1759, Saint-Di? d. 1832, Paris) 1832). French painter. After receiving instruction in art from Jean Girardet (1709-78) and Jean-Baptiste-Charles Claudot (1733-1805), he went to Paris in 1781, where he won recognition as a miniature painter. The miniatures he painted in the 1790s, for example his portrait of Mme Vanh?e, n?e Dewinck (1792; Paris, Louvre), are among his most animated works; often portraying figures in a landscape setting, they develop the exuberant style of Niclas Lafrensen and Peter Adolf Hall. He also admired the work of Jean-Baptiste Greuze, whose Bacchante (Waddesdon Manor, Bucks, NT) in his own collection he copied in miniature (London, Wallace) and in enamel (Paris, Louvre).
