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 embryo in the Uterus | Virgin of the Rocks | The Annunciation | The Baptism of Christ (detail) sg | The Anunciacion |

Francesco Primaticcio
Italian 1504-1570 Francesco Primaticcio Gallery Born in Bologna, he trained under Giulio Romano in Mantua and became a pupil of Innocenzo da Imola, executing decorations at the Palazzo Te before securing a position in the court of Francis I of France in 1532. Together with Rosso Fiorentino he was one of the leading artists to work at the Chateau Fontainebleau (where he is grouped with the so-called "First School of Fontainebleau") spending much of his life there. Following Rosso's death in 1540, Primaticcio took control of the artistic direction at Fontainebleau, furnishing the painters and stuccators of his team, such as Nicol?? dell'Abate, with designs. He made cartoons for tapestry-weavers and, like all 16th-century court artists, was called upon to design elaborate ephemeral decorations for masques and f??tes, which survive only in preparatory drawings and, sometimes, engravings. François trusted his eye and sent him back to Italy on buying trips in 1540 and again in 1545. In Rome, part of Primaticcio's commission was to take casts of the best Roman sculptures in the papal collections, some of which were cast in bronze to decorate the parterres at Fontainebleau.[1] Primaticcio retained his position as court painter to François' heirs, Henri II and François II. His masterpiece, the Salle d'Hercule at Fontainebleau, occupied him and his team from the 1530s to 1559. Primaticcio's crowded Mannerist compositions and his long-legged canon of beauty influenced French art for the rest of the century. Primaticcio turned to architecture towards the end of his life, his greatest work being the Valois Chapel at the Abbey of Saint-Denis, although this was not completed until after his death and was destroyed in 1719.
