claude vignon
Claude Vignon (19 May 1593 - 10 May 1670) was a leading French painter and engraver working in the Baroque manner. He was born at Tours and received early training in Paris. About 1610 he travelled to Rome where his mature style was formed in the circle of French painters there that included Simon Vouet and Valentin de Boulogne, a prominent member of the Caravaggisti working, like Bartolomeo Manfredi, in the manner established by Caravaggio. He returned from Italy, after a tour in Spain, in 1623. His paintings are represented in most of the major museums.
Leonardo Da Vinci
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.
Claude Joseph Vernet
Claude-Joseph Vernet (14 August 1714 - 3 December 1789) was a French painter. His son, Antoine Charles Horace Vernet, was also a painter. Vernet was born in Avignon. When only fourteen years of age he aided his father, Antoine Vernet (1689-1753),[1] a skilled decorative painter, in the most important parts of his work. The panels of sedan chairs, however, could not satisfy his ambition, and Vernet started for Rome. The sight of the sea at Marseilles and his voyage thence to Civitavecchia (Papal States' main port on the Tyrrhenian Sea) made a deep impression on him, and immediately after his arrival he entered the studio of a marine painter, Bernardino Fergioni. Slowly Vernet attracted notice in the artistic milieu of Rome. With a certain conventionality in design, proper to his day, he allied the results of constant and honest observation of natural effects of atmosphere, which he rendered with unusual pictorial art. Perhaps no painter of landscapes or sea-pieces has ever made the human figure so completely a part of the scene depicted or so important a factor in his design. In this respect he was heavily influenced by Giovanni Paolo Panini, whom he probably met and worked with in Rome. Vernet's work draws on natural themes, but in a way that is neither sentimental or emotive. The overall effect of his style is wholly decorative.[2] "Others may know better", he said, with just pride, "how to paint the sky, the earth, the ocean; no one knows better than I how to paint a picture". His style remained relatively static throughout his life. His works' attentiveness to atmospheric effects is combined with a sense of harmony that is reminiscent of Claude Lorrain.
