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 :. | The Madonna of the Carnation | The Last Supper-l | Reverse side of the portrait of Ginevra de' Benci | The Battle of Anghiari | Virgin of the Rocks |

Pontormo, Jacopo
b Pontormo, nr Empoli, 26 May 1494; d Florence, 31 Dec 1556). Italian painter and draughtsman. He was the leading painter in mid-16th-century Florence and one of the most original and extraordinary of Mannerist artists. His eccentric personality, solitary and slow working habits and capricious attitude towards his patrons are described by Vasari; his own diary, which covers the years 1554-6, further reveals a character with neurotic and secretive aspects. Pontormo enjoyed the protection of the Medici family throughout his career but, unlike Agnolo Bronzino and Giorgio Vasari, did not become court painter. His subjective portrait style did not lend itself to the state portrait. He produced few mythological works and after 1540 devoted himself almost exclusively to religious subjects. His drawings, mainly figure studies in red and black chalk, are among the highest expressions of the great Florentine tradition of draughtsmanship; close to 400 survive, forming arguably the most important body of drawings by a Mannerist painter. His highly personal style was much influenced by Michelangelo
CLAEISSENS, Antoon
Flemish painter (b. ca. 1538, Brugge, d. 1613, Brugge). Flemish painter and draughtsman. In 1587 he was working in Rome with the Brussels painter Frans van de Kasteele. That he subsequently lived in Brussels is confirmed by documentary evidence and by his status as court painter to the governors of the southern Netherlands. Stylistically, de Clerck's work (both paintings and drawings) is close to that of the Antwerp late Mannerist Marten de Vos, traditionally thought to have been his teacher, but it is possible that he was apprenticed to Joos van Winghe in Italy. He was later a member of the Brussels painters' guild, where from 1601 to 1611 Jan van Overstraeten was registered as his pupil. It was in 1594 that de Clerck was appointed court painter in Brussels, first to Archduke Ernest. In 1596, after the Archduke's death, his brother Emperor Rudolf II arranged for de Clerck to stay on as court painter in the service of the new Archdukes, Albert and Isabella. In 1609 de Clerck and Wenceslas Cobergher were commissioned to decorate the ceiling of the oratorium in the archducal palace in Brussels
