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 Verkundigung | Anatomy of the Schadels | The Annunciation | The Annunciation | Madonna with the Yarnwinder after 1510 |

Sir Godfrey Kneller
1649-1723 Dutch (Resident in UK) Sir Godfrey Kneller Galleries was the leading portrait painter in England during the late 17th and early 18th centuries, and was court painter to British monarchs from Charles II to George I. His major works include The Chinese Convert (1687); a series of four portraits of Isaac Newton painted at various junctures of the latter's life; a series of ten reigning European monarchs, including King Louis XIV of France; over 40 "Kit-cat portraits" of members of the Kit-Cat Club; and ten "beauties" of the court of William III, to match a similar series of ten beauties of the court of Charles II painted by his predecessor as court painter, Sir Peter Lely. Sir John Vanbrugh in Godfrey Kneller's Kit-cat portrait, considered one of Kneller's finest portraits.Kneller was born Gottfried Kniller in L??beck, Germany. Kneller studied in Leiden, but became a pupil of Ferdinand Bol and Rembrandt in Amsterdam. He worked in Rome and Venice in the early 1670s, painting historical subjects and portraits, and later moved to Hamburg. He came to England in 1674, at the invitation of the Duke of Monmouth, accompanied by his brother, John Zacharias Kneller, who was an ornamental painter. He was introduced to, and painted a portrait of, Charles II. In England, Kneller concentrated almost entirely on portraiture. He founded a studio which churned out portraits on an almost industrial scale, relying on a brief sketch of the face with details added to a formulaic model, aided by the fashion for gentlemen to wear full wigs. His portraits set a pattern that was followed until William Hogarth and Joshua Reynolds. Nevertheless, he established himself as a leading portrait artist in England. When Sir Peter Lely died in 1680, Kneller was appointed Principal Painter to the Crown by Charles II. In the 1690s, Kneller painted the Hampton Court Beauties depicting the most glamorous ladies-in-waiting of the Royal Court for which he received his knighthood from William III. He produced a series of "Kit-cat" portraits of 48 leading politicians and men of letters, members of the Kit-Cat Club. Created a baronet by King George I, he was also head of the Kneller Academy of Painting and Drawing 1711-1716 in Great Queen Street, London. His paintings were praised by Whig luminaries such as John Dryden, Joseph Addison, Richard Steele, and Alexander Pope. Kneller died of fever in 1723 and his remains were interred in Twickenham Church (he was a churchwarden there when the 14th century nave collapsed in 1713 and was involved in the plans for its reconstruction). The site of the house he built in 1709 in Whitton near Twickenham is now occupied by the mid-19th century Kneller Hall, home of the Royal Military School of Music
