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 :. | Annunciation (detail) ey79 | Study fur the communion | St Jerome sgyu | Funf studies of grotesque faces | Leda (detail) ghk |

Gwen John
Welsh 1876-1939 Gwen John was born in Haverfordwest, Wales, the second of four children of Edwin William John and his wife Augusta (nee Smith). Edwin John was a solicitor whose dour temperament cast a chill over his family, and Augusta was often absent from the children due to ill health, leaving her two sisters??stern Salvationists??to take her place in the household. Despite the considerable tension in the family (who became known as "those turbulent Johns") the children's interest in literature and art was encouraged. Following the mother??s premature death in 1884, the family moved to Tenby in Pembrokeshire, Wales. Although she painted and drew from an early age, her earliest surviving work dates from her nineteenth year. From 1895?C98, she studied at the Slade School of Art, where her younger brother, Augustus John, had begun his studies in 1894. During this period they shared living quarters, and further reduced their expenses by subsisting on a diet of nuts and fruit. Even as a student, Augustus' brilliant draughtsmanship and personal glamour made him a celebrity, and stood in contrast to Gwen's quieter gifts and reticent demeanour. While he greatly admired her art, Augustus offered her advice which she ignored; he urged her to take a "more athletic attitude to life", and cautioned her against what he saw as the "unbecoming and unhygienic negligence" of her mode of living, but her entire life was marked by a disregard for her physical well-being. In 1898 she made her first visit to Paris with two friends from the Slade, and while there she studied under James McNeill Whistler at the Academie Carmen. She returned to London in 1899, and spent the next four years in austere circumstances. When she exhibited her work for the first time in 1900, at the New English Art Club (NEAC), her address was a derelict building where she was living illegally.
