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 :. | Annunciation (detail) ey79 | Portrait of Ginevra de Benci | Equestrian monument | Madonna and Child with St Anne and the Young St John | Reverse side of the portrait of Ginevra de' Benci sg |

Nicolas de Largilliee
Largilliere's father, a merchant, took him to Antwerp at the age of three. As a boy, he spent nearly two years in London. Sometime after his return to Antwerp, a failed attempt at business led him to the studio of Goubeau. However, Largilliere left at the age of eighteen and went to England, where he was befriended and employed by Peter Lely for four years at Windsor, Berkshire. Painting careerEarly careerHis painting caught the attention of Charles II, who wished to retain Largilliere in his service, but the controversy aroused by the Rye House Plot against Roman Catholics alarmed Largilliere. Largilliere left for Paris, where he was well-received by the public as a painter. Upon ascending to the throne in 1685, James II requested Largilliere to return to England. James II offered Largilliere the office of keeper of the royal collections, but he declined due to being uneasy about Rye House Plot. However, during a short stay in London, he painted portraits of the king, the queen Mary of Modena, and the prince of Wales James Francis Edward Stuart. The portrait of the Prince of Wales could not have been painted during Largilliere's stay in London because the prince was not born until 1688. The three portraits painted by Largilliere of the prince in his youth must have been executed in Paris, where he returned sometime before March 1686. The portrait of King James II was painted in 1686. King James is portrayed in golden armor with a white cravat and is positioned in front of a watercolour-like background set in a round frame.
