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 :. | St John the Baptist t | Studies of horses | The Virgin and St Anne (mk08) | Adoration of the Magi (mk08) | The Verkundigung |

Claude-joseph Vernet
French Painter, 1714-1789 Vernet probably received his first lessons in painting from his father, Antoine, who then encouraged him to move to the studio of Philippe Sauvan (1697-1792), the leading master in Avignon. Sauvan supplied altarpieces to local churches and decorative works and mythologies for grand houses in the area. After this apprenticeship Vernet worked in Aix-en-Provence with the decorative painter Jacques Viali ( fl 1681- 1745), who also painted landscapes and marine pictures. In 1731 Vernet independently produced a suite of decorative overdoors for the h?tel of the Marquise de Simiane at Aix-en-Provence; at least two of these survive (in situ) and are Vernet's earliest datable landscapes. These are early indications of his favoured type of subject, and Vernet would have studied works attributed to such 17th-century masters as Claude Lorrain, Gaspard Dughet and Salvator Rosa in private collections at Aix and Avignon. Three years later Joseph de Seytres, Marquis de Caumont, who had previously recommended Vernet to the Marquise de Simiane, offered to sponsor a trip to Italy.

Paul de Vos
(1591e1592, or 1595, Hulst-30 June 1678, Antwerp) was a Flemish Baroque painter. De Vos was born in Hulst near Antwerp, now in the Dutch province of Zeeland. Like his older brother Cornelis and younger brother Jan, he studied under the little-known painter David Remeeus (1559-1626). He specialized in monumental animal scenes, especially hunts for aristocratic patrons, that are heavily influenced by Frans Snyders (to whom his sister Margaretha was married). De Vos became a master and joined the guild of St. Luke in 1620. As was frequent amongst artists in Antwerp, De Vos frequently collaborated with other painters. He painted animals in hunting scenes and armor in mythologies by Peter Paul Rubens and his studio. He also worked with Thomas Willeboirts Bosschaert, Erasmus Quellinus II, Anthony van Dyck, and Jan Wildens.
