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 :. | Reverse side of the portrait of Ginevra de' Benci | The Battle of Anghiari | Portrait of Ginerva de'Benci | Cartoon | Adoration of the Magi |

MICHELI Parrasio
Italian painter, Venetian school (before 1516 - 1578) Italian painter and draughtsman. The natural son of a Venetian aristocrat, Salvador Michiel, he pursued his early training in the workshop of Titian and later in his career was associated with Paolo Veronese, who provided him with drawings for his paintings. He is known to have been in Rome before 1547. Micheli's earliest work is an altarpiece depicting the Virgin and Child with SS Lorenzo and Ursula (1535; Murano, S Pietro Martire), which was commissioned by Ursula Pasqualigo in memory of her deceased husband, the former Procurator Lorenzo Pasqualigo. There is also a Venus and Cupid (c. 1547; London, priv. col.) and a Lucrezia (c. 1547; London, Mond col.). In 1550 he married the daughter of a German baker. Several documented paintings have been destroyed or are untraced: the painting of Doge Lorenzo Priuli Accompanied by Ten Senators with Personifications of Fortune and Venice (1563), for which he received 225 ducats, was destroyed in the fire in the Doge's Palace of 1574. The work is known from a preparatory study (Berlin, Kupferstichkab.) and a contract of 22 October 1563. Five paintings known to have been in the Libreria Marciana that same year are also untraced. The large painting depicting the Adoration of the Dead Christ (Venice, S Giuseppe), signed and dated parrhasio Micheli dipinse nel 1573, includes a self-portrait. Micheli also painted portraits of Venetian noblemen (e.g. Girolamo Zane, Venice, Accademia; Tommaso Contarini, Venice, Doge's Palace) and associated with prominent men of letters including Paolo Giovio and Pietro Aretino.
