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 :. | Equestrian monument | Madonna and Child | The Last Supper (detail) sg | Studies of horses | The Madonna of the Carnation (detail) sg |

Egon Schiele
1890-1918 Austrian Egon Schiele Gallery Egon Schiele (12 June 1890 ?C 31 October 1918) was an Austrian painter, a protege of Gustav Klimt, and a major figurative painter of the early 20th century. Schiele's body of work is noted for the intensity and the large number of self-portraits he produced. The twisted body shapes and the expressive line that characterize Schiele's paintings and drawings make the artist an early exponent of Expressionism, although still strongly associated with the art nouveau movement (Jugendstil). The most important collection of Schiele's work is housed in the Leopold Museum, Vienna. In 1907, Schiele sought out Gustav Klimt. Klimt generously mentored younger artists, and he took a particular interest in the gifted young Schiele, buying his drawings, offering to exchange them for some of his own, arranging models for him and introducing him to potential patrons. He also introduced Schiele to the Wiener Werkstätte, the arts and crafts workshop connected with the Secession. In 1908 Schiele had his first exhibition, in Klosterneuburg. Schiele left the Academy in 1909, after completing his third year, and founded the Neukunstgruppe ("New Art Group") with other dissatisfied students. Sitzender weiblicher Akt, 1914Klimt invited Schiele to exhibit some of his work at the 1909 Vienna Kunstschau, where he encountered the work of Edvard Munch, Jan Toorop, and Vincent van Gogh among others. Once free of the constraints of the Academy's conventions, Schiele began to explore not only the human form, but also human sexuality. At the time, many found the explicitness of his works disturbing.
Hieronimo Custodis
(also spelled Hieronymus, Heironimos) (died c. 1593) was a Flemish portrait painter active in England in the reign of Elizabeth I. A native of Antwerp, Custodis was one of many Flemish artists of the Tudor court who had fled to England to avoid the persecution of Protestants in the Spanish Netherlands.He is thought to have arrived in England sometime after the fall of Antwerp to the forces of the Duke of Parma in 1585. Three English portraits by Custodis signed and dated 1589 firmly establish him as resident in London by that year. Sir Roy Strong attributes a portrait of Sir Henry Bromley dated 1587 to Custodis, suggesting an earlier arrival, and has verified the recent attribution of a portrait of the young Edward Talbot dated 1586 to Custodis.In 1591, he was living in the parish of St Bodolph-without-Aldgate where "Jacobus the son of Ieronyme Custodis A Paynter" was baptised on 2 March. He is assumed to have died in 1593, as all of his known works are dated between 1589 and 1593, and his widow remarried that year. Custodis's unsigned but dated works are idenitified by "palaeographical peculiarities" in the inscriptions which can be closely matched to those in his signed portraits.
