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 :. | Study fur a women head | Study of an old man | Lady with Ermine | Portrait de femme,dit a tort La belle ferronniere | The Virgin and Child with St Anne ey |

1440-1482 Flemish Hugo van der Goes Galleries Hugo became a member of the painters' guild of Ghent as a master in 1467. In 1468 he was involved in the decoration of the town of Bruges in celebration of the marriage between Charles the Bold and Margaret of York and he provided heraldic decorations for Charles's joyeuse entr??e to Ghent in 1469 and again in 1472. He was elected dean of the Ghent guild in 1473 or 1474. In 1475, or some years later, Hugo entered Rooklooster, a monastery near Brussels belonging to the Windesheim Congregation, and professed there as a frater conversus. He continued to paint, and remained at Rooklooster until his death in 1482 or 1483. In 1480 he was called to the town of Leuven to evaluate the Justice Scenes left unfinished by the painter Dieric Bouts on his death in 1475. Shortly after this, Hugo, returning with other members of his monastery from a trip to Cologne, fell into a state of suicidal gloom, declaring himself to be damned. After returning to Rooklooster, Hugo recovered from his illness, and died there. His time at Rooklooster is recorded in the chronicle of his fellow monk, Gaspar Ofhuys. A report by a German physician, Hieronymus M??nzer, from 1495, according to which a painter from Ghent was driven to melancholy by the attempt to equal the Ghent Altarpiece, may refer to Hugo. His most famous surviving work is the Portinari Triptych (Uffizi, Florence), an altarpiece commissioned for the church of San Egidio in the hospital of Santa Maria Nuova in Florence by Tommaso Portinari, the manager of the Bruges branch of the Medici Bank. The triptych arrived in Florence in 1483, apparently some years after its completion by van der Goes. The largest Netherlandish work that could be seen in Florence, it was greatly praised. Giorgio Vasari in his Vite of 1550 referred to it as by "Ugo d'Anversa" ("Hugo of Antwerp"). This the sole documentation for its authorship by Hugo; other works are attributed to him based on stylistic comparison with the altarpiece. Hugo appears to have left a large number of drawings, and either from these or the paintings themselves followers made large numbers of copies of compositions that have not survived from his own hand. A drawing of Jacob and Rachel preserved at Christ Church, Oxford is thought to be a rare surviving autograph drawing.
