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 :. | Portrait of Ginevra de' Benci sg | The Annunciation | Last Supper (mk08) | Head of a girl | Leda |

Mather Brown
American Painter, 1761-1831 was a portrait and historical painter, born in Boston, Massachusetts but active in England. Brown was the son of Gawen and Elizabeth (Byles) Brown, and descended from the Rev. Increase Mather on his mother's side. He was taught by his aunt and around 1773 (age 12) became a pupil of Gilbert Stuart. He arrived in London in 1781 to further his training in Benjamin West's studio, entered the Royal Academy schools in 1782 with plans to be a miniature painter, and began to exhibit a year later. In 1784 he painted two religious paintings for the church of St Mary??s-in-the-Strand, which led Brown to found a partnership with the painter Daniel Orme for the commercialization of these and other works through exhibition and the sale of engravings. Among these were large paintings of scenes from English history, as well as scenes from Shakespeare's plays. However, despite their success he began to concentrate on portraiture. His first successes were with American sitters, among others his patron John Adams and family in 1784?C85; this painting is now in the Boston Athenaeum. In 1785?C86 he painted the first portrait of Thomas Jefferson, who was visiting London. He also painted Sir William Pepperrell. His 1788 full-length portrait of Prince Frederick Augustus in the uniform of Colonel of the Coldstream Guards led to appointment as History and Portrait Painter to the Prince, later the Duke of York and Albany. Other paintings include the Prince of Wales, later George IV (about 1789), Queen Charlotte, and Cornwallis. A self-portrait now belongs to the American Antiquarian Society, Worcester, Massachusetts. A falling off of patronage in the mid-1790s, and failure to be elected to the Royal Academy, led Brown to leave London in 1808 for Bath, Bristol, and Liverpool.
