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 :. | Profile of an old man | Madonna in the rock grotto | The Annunciation | Mona Lisa (detail) dhu | Equestrian monument |

Francis Cotes
(20 May 1726 - 16 July 1770) was an English painter, one of the pioneers of English pastel painting, and a founder member of the Royal Academy in 1768. He was born in London, the eldest son of Robert Cotes, an apothecary (Francis's younger brother Samuel Cotes (1734 - 1818) also became an artist, specialising in miniatures). Cotes trained with portrait painter George Knapton (1698 - 1778) before setting up his own business in his father's business premises in London's Cork Streetelearning, incidentally, much about chemistry to inform his making of pastels. An admirer of the pastel drawings of Rosalba Carriera, Cotes concentrated on works in pastel and crayon (some of which became well-known as engravings). After pushing crayon to its limit as a mediumealthough he was never to abandon it entirelye - otes turned to oil painting as a means of developing his style in larger-scale works. In his most successful paintings, particularly those of the early 1760s, the oil paint is thinly applied, in imitation of his pastel technique, and imbued with charm, inviting comparisons with Allan Ramsay (1713 - 1784) and Sir Joshua Reynolds. They have clarity and warmth and possess a remarkable attention to costume. In 1763, he bought a large house (later occupied by George Romney) in Cavendish Square. One of the most fashionable portrait painters of his day, Cotes helped found the Society of Artists and became its director in 1765. At the peak of his powers, Cotes was invited to become one of the first members of the Royal Academy, but died just two years later, aged 44, in Richmond. He also taught pastel skills to John Russell, and his skills were described in book The Elements of Painting with Crayon.
