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 | The Virgin and St Anne | Studies fur the adoration of the Konige | The Baptism of Christ | Profile of a man |

Francesco Maria Schiaffino
Italian Rococo Era Sculptor, 1688-1763,Brother of Bernardo Schiaffino. He was the pupil and then assistant of Bernardo, who in 1721 sent him to complete his training in Rome, where he entered the workshop of Camillo Rusconi. He remained there until 1724, enriching his technique and cultural education by studying the works of Bernini, Rusconi and other sculptors. Back in Genoa, he executed such works as St Dominic (Genoa, Teatro Carlo Felice), in which Rusconi's influence is evident. The marble group of Pluto and Proserpine, sculpted for the Durazzo family and still in its original location (Genoa, Pal. Reale), is based on a bozzetto by Rusconi. In 1731 Schiaffino executed the grandiose Crucifix with Angels for King John V of Portugal (Mafra, Convent) and in 1738 began the theatrical funeral monument to Caterina Fieschi Adorno (Genoa, SS Annunziata di Portoria). The wax models of the Eight Apostles and Four Doctors of the Church that he modelled in 1739 (all untraced) were clearly inspired by the large Apostles by Rusconi and other sculptors in S Giovanni in Laterano, Rome. They were made for the stuccoist Diego Francesco Carlone so that he could, under Schiaffino's directions, execute 12 monumental statues in stucco (Genoa, S Maria Assunta in Carignano). In these latter works the classicizing authority of Rusconi's figures was transformed into a freer and more restless arrangement, the compact forms dissolving in the light, animated draperies. The statues reveal how Schiaffino had combined his knowledge of Roman sculpture with his study of Pierre Puget's Genoese works and with the style of the Piola workshop. He emulated the free rhythms of the Rococo found in the painting of Gregorio de' Ferrari, developing a decorative approach that is even more marked in the Assumption of the Virgin (1740; Varazze, S Ambrogio) and in the Rococo chapel of S Francesco da Paola (1755; Genoa, S Francesco da Paola), which he covered in polychrome marbles. His last works include the Virgin of Loreto (1762; Sestri Levante, Parish Church).
