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 Virgin and Child with St Anne ey | Mona Lisa | Study of an old man | The annunciation | Portrat of a Madchens |

Evelyn De Morgan
1855-1919 British Evelyn De Morgan Galleries She was born Evelyn Pickering. Her parents were of upper middle class. Her father was Percival Pickering QC, the Recorder of Pontefract. Her mother was Anna Maria Wilhelmina Spencer Stanhope, the sister of the artist John Roddam Spencer Stanhope and a descendant of Coke of Norfolk who was an Earl of Leicester. Evelyn was homeschooled and started drawing lessons when she was 15. On the morning of her seventeenth birthday, Evelyn recorded in her diary, "Art is eternal, but life is short..." "I will make up for it now, I have not a moment to lose." She went on to persuade her parents to let her go to art school. At first they discouraged it, but in 1873 she was enrolled at the Slade School of Art. Her uncle, John Roddam Spencer Stanhope, was a great influence to her works. Evelyn often visited him in Florence where he lived. This also enabled her to study the great artists of the Renaissance; she was particularly fond of the works of Botticelli. This influenced her to move away from the classical subjects favoured by the Slade school and to make her own style. In 1887, she married the ceramicist William De Morgan. They lived together in London until he died in 1917. She died two years later on 2 May 1919 in London and was buried in Brookwood Cemetery, near Woking, Surrey.
