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 with the Yarnwinder ty | The Madonna of the Carnation (detail) sg | Six studies fur naked or clothed men | Annunciation | the last supper |

PREDIS, Ambrogio de
Italian Early Renaissance Painter, ca.1455-1508 Painter and illuminator, half-brother of Cristoforo de Predis. He began his career as an illuminator, working with Cristoforo. His first documented works are seven miniatures for a Book of Hours (1472; destr.) for Vitaliano Borromeo (1451-95) and a Book of Hours for Francesco Borromeo. He was paid for the latter in 1474, and the codex can probably be identified with the Horae Beatae Virginis Mariae (ex-H. P. Kraus, New York, 1987; Suida, 1959). From 1479 he artist worked in the Milanese mint, together with his brother Bernardino. For some years Giovanni Ambrogio also worked at the court of Ludovico Sforza ('il Moro'), especially as a portrait painter. This is borne out by the charcoal drawing of Bianca Maria Sforza (1492; Venice, Accad.), which dates from a period before her marriage to Emperor Maximilian I. The portrait was ordered by her future husband, through Frederick III, Duke of Saxony, to give him an idea of her appearance. It was favourably received, and later a painting of the same subject (Washington, DC, N.G.A.) was commissioned from Giovanni Ambrogio.

Francis Wheatley
1747-1801 British Francis Wheatley Location Francis Wheatley (1747 - June 28, 1801), was an English portrait and landscape painter, was born at Wild Court, Covent Garden, London. He studied at Shipleys drawing-school and the Royal Academy, and won several prizes from the Society of Arts. He assisted in the decoration of Vauxhall, and aided Mortimer in painting a ceiling for Lord Melbourne at Brocket Hall (Hertfordshire). In youth his life was irregular and dissipated. He eloped to Ireland with the wife of Gresse, a brother artist, and established himself in Dublin as a portrait-painter, executing, among other works, an interior of the Irish House of Commons. His scene from the Gordon Riots of 1780 was engraved by Heath. He painted several subjects for Boydells Shakespeare Gallery, designed illustrations to Bells edition of the poets, and practised to some small extent as an etcher and mezzotint-engraver. It is, however, as a painter, in both oil and water-color, of landscapes and rustic subjects that Wheatley is best remembered. He was elected an associate of the Royal Academy in 1790, and an academician in the following year. His wife, as Mrs Pope after his death, was known as a painter of flowers and portraits.
