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) sg77 | Our Lady and St Anne | St Jerome sgyu | Portrait of a Musician dey | Annunciation (detail) dfe |

Dieric Bouts
1420-1475 Flemish Dieric Bouts Locations Dirk Bouts whose real name was Theodorik Romboutszoon, was probably born in Haarlem, where he may have studied under the painter Albert van Ouwater. Sometime before 1450 Bouts took up residence in the Flemish city of Louvain. His name appeared in the records of Louvain in 1457 and again in 1468, when he was appointed "city painter." It is likely that Bouts spent some time in Bruges, as his earliest work, the Infancy Altarpiece shows the distinct and strong influence of Petrus Christus, the leading master of that city after the death of Jan van Eyck. The slightly later Deposition Altarpiece (ca. 1450) displays strong connections with the style of Rogier van der Weyden in both the figure types and the composition. About 1460, the period of the Entombment in London, the early, formative influence of Petrus Christus had been almost totally displaced by that of Rogier, though Bouts personal vision began to emerge in the fluid and continuous landscape background. The great Last Supper Altarpiece (1464-1467) marks the high point of Bouts career. In this solemn and dignified masterpiece the painter achieved spiritual grandeur in the context of convincing physical reality. The central panel of the altarpiece is the most emphatically significant treatment of the theme of the Last Supper in Northern European art. The wings, which contain Old Testament prefigurations of the central theme, are freer and more loosely organized. Eschewing the symmetry and rigid axial construction of the main panel, Bouts produced rhythmic foreground compositions in combination with fluid and dramatic spatial recessions. In 1468 Bouts was commissioned to paint four panels on the subject of justice for the Town Hall of Louvain. At the painter death in 1475 only two of the paintings had been completed; they are among the most remarkable productions of his career. The unusual subjects, taken from the chronicles of a 12th-century historian, concern the wrongful execution by Emperor Otto III of one of his counts and the subsequent vindication of the nobleman by his wife. The finer of the panels represents the dramatic trial by fire which the wife was obliged to undergo to prove her husband innocence. Rich draperies and sumptuous colors are applied to tall angular forms to create a work of rare formal elegance and high decorative appeal. In order to dignify the event, however, the artist has employed restrained gestures and expressions as well as a completely rationalized spatial setting. As in the Last Supper Altarpiece, a sense of solemn and hieratic importance is expressed by means of an austere and rigid geometry in the construction of both persons and places. The late productions of Bouts workshop, such as the well-known Pearl of Brabant Altarpiece, are characterized by the close collaboration of the painter two sons, Dirk the Younger (1448-1491) and Aelbrecht (1455/1460-1549). In the paintings of his less gifted sons, the master distinctive figure style was appreciably altered, though Dirk the Younger appears to have retained much of his father sensitivity to the landscape. In addition to his innovations in the depiction of landscape, Bouts made a substantial contribution to the development of the portrait. His Portrait of a Man (1462) localizes the sitter in an enlarged architectural setting while permitting the interior space to merge with the exterior through an open window. For the first time in Northern painting a common bond was forged between a particularized individual and the universal world of nature.
