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 :. | Ceiling decoration yy | Funf studies of grotesque faces | Madonna in the cave | The Madonna of the Carnation (detail) dg | The Virgin and the Nino with Holy Ana |

LAWRENCE, Sir Thomas
English painter (b. 1769, Bristol, d. 1830, London). Thomas Lawrence was born in Bristol on May 4, 1769. At Devizes, where his father was landlord of the Black Bear Inn, Thomas's talents first became known. Fanny Burney, a prodigy herself, reports that in 1780 Sir Joshua Reynolds had already pronounced Lawrence the most promising genius he had ever met. When Thomas was 10, his father moved the family to Oxford and then to Bath to take advantage of the portrait skill of his son. At the age of 17 Lawrence began to paint in oil, all his previous work having been in pastel. In 1787 the family moved to London, and by 1789 he was challenging Reynolds. When Reynolds died in 1792, Lawrence was appointed to the lucrative post of painter in ordinary to the king. He soon became the foremost portrait painter in England, a position he maintained until his death. His portraits of women are models of beauty and elegance, whether the sitter be a tragic actress like Mrs. Siddons, a social figure like the Princess de Lieven, or a personal friend. At the close of the Napoleonic Wars, Lawrence was knighted and commissioned to paint the leading sovereigns and statesmen of Europe. When he returned to England in 1820, he was elected president of the Royal Academy; he handled the affairs of his office with tact and urbanity. He died on Jan. 7, 1830. Following the English masters of the 18th century, Reynolds, Thomas Gainsborough, and George Romney, Lawrence carried on the great tradition of society portraiture and raised it to new heights of dash and elegance, though not of psychological penetration. He was by no means an artist of the astonishing insight of Gainsborough, and he did not have the occasionally disconcerting originality of Reynolds. Lawrence had their faults: all were affected by the distorting demands of their fashionable clientele, and all succumbed to them. He had the least to say, and he reflected his sitters' own best views of themselves, yet even they must sometimes have been surprised at their own magnificence. Handsome his portraits undoubtedly are; all the women are strikingly beautiful, the men brave and distinguished. Lawrence enjoyed his great success. He lived for his work, never married, and was a prodigious worker. He was of an exceptionally generous nature, as an artist and as a man, with a rare talent for appreciating and encouraging the talents of others. He was an ardent collector of Old Master drawings; his collection, which was dispersed after his death,
