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 Annunciation | Annunciation | Profile of an old man | Portrait de Mona Lisa dit La joconde | Muscle structure of the thigh |

MARIESCHI, Michele
Italian Painter, 1710-1743 Italian painter and engraver. His first biographers, Orlandi and Guarienti (1753), stated that Marieschi worked in Germany early in his career and then returned to Venice, where he established himself as a painter of 'beautiful views of the Grand Canal, and of churches and palaces'. Yet there is no other evidence for this journey and Marieschi's early training remains problematic. It seems likely that he began his career as a stage designer: his first recorded activity, in 1731, was the preparation, on behalf of the impresario Francesco Tasso ( fl 1725-c. 1740), of the setting for the Venetian celebration of Carnival Thursday in the Piazzetta. He then, influenced by Marco Ricci and Luca Carlevaris, began to paint capriccios and vedute. His early capriccios, such as the pair Capriccio with Classical Ruins and Bridge and Capriccio with Roman Arch and Encampment (mid-1730s; Naples, Mus. Civ. Gaetano Filangieri), are indebted to Ricci, although they lack his solemnity and magnificence. Marieschi's blend of medieval and Classical ruins in a serene Venetian landscape is more picturesque and romantic. Marieschi began to paint vedute having been encouraged by Canaletto's great success with the genre; examples such as the S Maria della Salute (1733-5; Paris, Louvre), the Piazzetta dei Leoni and the Grand Canal at Ca' Pesaro (1734-5; both Munich, Alte Pin.) are distinguished from Canaletto's work by their exaggerated perspective, more atmospheric colour and the spirited handling of the small figures. Two capriccios, the Town on a River with Rapids (London, N.G.) and the Town on a River with Shipping (London, N.G.;.), both charmingly picturesque scenes with watermills and crumbling towers, date from the mid-1730s. Marieschi began to etch in the 1730s,

Jacopino del Conte
Italian Painter, ca.1510-1598 was an eminent Italian Mannerist painter, active in both Rome and Florence. A native of Florence, Jacopino del Conte was born the same year as another Florentine master Cecchino del Salviati (whom Conte outlived by 35 years) and, like Salviati and a number of other painters, he initially apprenticed with the influential painter and draftsman Andrea del Sarto. Conte's first frescoes, including Annunciation to Zachariah (1536), Preaching of Saint John the Baptist (1538), and Baptism of Christ (1541) were in the Florentine-supported Oratory of San Giovanni Decollato, located in Rome. The Preaching fresco was based on a drawing by Perin del Vaga. In 1547?C48, in collaboration with Siciolante da Sermoneta, Conte completed the fresco decoration of the chapel of San Remigio in San Luigi dei Francesi. In 1552, he painted another work for the San Giovanni Decollato Oratory, the altarpiece Deposition, whose designs are sometimes attributed to Daniele da Volterra.
