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 :. | Virgin of the Rocks | Madonna with the Yarnwinder | Profile of an old man | Mona Lisa | The Annunciation |

Master of Saint Giles
The Master of Saint Giles (French: Maître de Saint-Gilles) was a Franco-Flemish painter active, probably in Paris, about 1500, working in a delicate Late Gothic manner, with rendering of textures and light and faithful depictions of actual interiors that show his affinities with Netherlandish painting. It is not clear whether the Master of Saint Giles was a French painter who trained in the Low Countries (perhaps more likely), or a Netherlander who emigrated to France. His pseudonym was given him by Max Friedländer, who reconstructed part of the anonymous painter's oeuvre, starting from two panels devoted to Saint Giles (a Miracle and a Mass) in the National Gallery, London, that were part of the lefthand shutter of an altarpiece, and two further panels now in Washington from the same altarpiece. The hand of an assistant can be discerned in the Baptism of Clovis at the National Gallery of Art, Washington, who also have a panel with Episodes from the Life of a Bishop-Saint - perhaps Saint Leu, Saint Denis or Saint Remy. All four panels have, or had, single grisaille figures of saints (Saints Peter, Giles, Denis and an unidentified bishop-saint) in niches, imitating sculpture, on the reverse. The Washington pair, which were in poor condition, have been separated and are lost, although photographs exist. Undoubtedly there were further panels, whose subjects cannot be guessed, as the combination of scenes is original.
Julius Hubner
1806 Oels-1882 Loschwitz ,was a German historical painter of the Dusseldorf school. He was also known as a poet and the father of Emil Hubner, a distinguished classical scholar. Hubner was born at Oels in Silesia, studied at the Academy School in Berlin and under Schadow there and in Dusseldorf. He first attracted attention by his picture of "Ruth and Boaz" (1825). He traveled in Italy and resided for the most part at Dusseldorf until 1839. In that year he settled at Dresden, becoming a professor in the Academy of Arts in 1841 and director of the Gallery of Paintings in 1871. He obtained the great gold medal at Brussels in 1851. He died in Loschwitz.
Procaccini, Andrea
Italian, 1671-1734 Italian painter, draughtsman and architect. A pupil of Carlo Maratti, he is first documented in 1702, among the restorers of Raphael's fresco decorations (1511-14) in the Vatican. His Tarquinius and Lucretia (c. 1705; Holkham Hall, Norfolk) has cold colours and unnatural gestures that recall Guido Reni. Appointed by Pope Clement XI, between 1710 and 1717 Procaccini supervised the tapestry factory in S Michele a Ripa: the Purification of the Virgin (Rome, Vatican, Consistory Hall) is the only extant tapestry made from a cartoon (untraced) by Maratti and an oil painting (untraced) by Procaccini. The Baptism of Cornelius Centurion (1711; Urbino, S Francesco) for the Baptism Chapel in St Peter's, Rome, was previously attributed to Maratti or Giuseppe Bartolomeo Chiari, but Procaccini apparently based it on sketches supplied by Maratti, who also supervised and revised the work before it was displayed.
