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 :. | Madonna with a Flower (Madonna Benois) g | Virgin of the Rocks | Studies of horses | The Baptism of Christ (detail) sg | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici |

Joseph Heintz
1564-1609 Swiss Painter, draughtsman, architect and artistic adviser, son of Daniel Heintz. He began his training as a painter c. 1579 with Hans Bock I (c. 1550-c. 1623) in Basle. His first surviving drawings (1580) show something akin to Holbein manner in his stained-glass window designs. After completing his apprenticeship he went c. 1584 to Rome, where he studied the works of antiquity, and those of Raphael, Michelangelo, Polidoro da Caravaggio and others. In 1587 he went via Florence to Venice, absorbing the works of Tintoretto, Titian and Veronese. In autumn 1591 the Holy Roman Emperor Rudolf II summoned him as portraitist and court painter to Prague but soon sent him back to Italy, where he drew ancient statues in addition to producing his own work and acting as art agent for the Emperor. In 1592-5 he stayed mainly in Rome, then returned to Prague. In the following years he worked indefatigably as a draughtsman, painter, architect and artistic adviser, moving between Augsburg and Prague.
John Martin
British 1789-1854 John Martin Gallery His first exhibited subject picture, Sadak in Search of the Waters of Oblivion (now in the St. Louis Art Museum), was hung in the Ante-room of the Royal Academy in 1812, and sold for fifty guineas. It was followed by the Expulsion (1813), Paradise (1813), Clytie (1814), and Joshua Commanding the Sun to Stand Still upon Gibeon (1816). In 1821 appeared his Belshazzar's Feast, which excited much favorable and hostile comment, and was awarded a prize of £200 at the British Institution, where the Joshua had previously carried off a premium of £100. Then came the Destruction of Herculaneum (1822), the Creation (1824), the Eve of the Deluge (1841), and a series of other Biblical and imaginative subjects. The Plains of Heaven is thought to reflect his memories of the Allendale of his youth. Martin's large paintings were inspired by "contemporary dioramas or panoramas, popular entertainments in which large painted cloths were displayed, and animated by the skilful use of artificial light. Martin has often been claimed as a forerunner of the epic cinema, and there is no doubt that the pioneer director D. W. Griffith was aware of his work." In turn, the diorama makers borrowed Martin's work, to the point of plagiarism. A 2000-square-foot version of Belshazzar's Feast was mounted at a facility called the British Diorama in 1833; Martin tried, but failed, to shut down the display with a court order. Another diorama of the same picture was staged in New York City in 1835. These dioramas were tremendous successes with their audiences, but wounded Martin's reputation in the serious art world.
