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 :. | Mona Lisa (detail) dyk | The organs of the woman | The Benois Madonna | anna sjalv tredje | Study of an apostle |

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.
Johannes Hubertus Leonardus de Haas
(25 March 1832 - 4 August 1908) was a Dutch animal and landscape painter, and a peripheral figure of the Hague School. Born at Hedel, De Haas spend his youth in Amsterdam where he got his first art education at evening-classes at the Koninklijke Academie. Consequently he moved to Haarlem where he was apprenticed to the artist Pieter Frederik van Os. During his stay in Haarlem he befriended Paul Gabriël and Hendrik Dirk Kruseman Van Elten who were also studying with Van Os. In 1853, together with his two friends, De Haas decided to go to Oosterbeek. Here they came into contact with the influential landscape painter Johannes Warnardus Bilders and the group of painters which had gathered around him, many of whom would later be part of the Hague School. De Haas also met his future wife in Oosterbeek, Bilders' daughter, Caroline. In 1855 he received good reviews for his pictures that were exhibited in Paris from the noted art critic Jean Baptiste Gustave Planche. In 1857 De Haas first went to Brussels, where he became friends with Willem Roelofs. De Haas frequently returned to the Netherlands and Oosterbeek for inspiration and Caroline. From 1860 his friend Gabriël also lived in Brussels, and De Haas often painted cattle in the landscapes of both Roelofs and Gabriel, fitting in perfectly with both their styles. In 1860 he won the gold medal at the exhibition of Utrecht. From 1861 until 1869 De Haas is permanently settled in Brussels, painting mainly on the coasts of Flanders and Picardie in northern France. He married Caroline Bilders in 1862, and in 1864 they are briefly joined by her brother, the promising painter Gerard Bilders. In 1865 Caroline dies at the age of 24 of tuberculosis, leaving him with a young son. During his stay in Brussels De Haas is instrumental in passing on the style of the Barbizon school to the painters at Oosterbeek.
KUPECKY, Jan
Bohemian Baroque Era Painter, 1667-1740 Bohemian painter. He was born into a weaver's family, who, as Moravian Brethren, were forced to emigrate from Bohemia to Pezinok, Slovakia. Having met the artist Benedikt Claus (1632/3-1707), he left home at 15 to join him in Vienna, and three years later accompanied him to Italy. He worked in Venice and other north Italian towns before settling in Rome, where he made a meagre living by copying portraits. Although he attempted genre and historical paintings, portraiture became his main work. His influences ranged from prominent Venetian painters such as Bernardo Strozzi, Johann Carl Loth and Giuseppe Ghislandi to Anthony van Dyck and Hyacinthe Rigaud.
