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 :. | Leda h | Portrat of a musician | Adoration of the Magi (mk08) | The Refectory with the Last Supper after restoration g | Mona Lisa |

Joseph-Siffred Duplessis
(22 September 1725 - 1 April 1802) was a French painter, known for the clarity and immediacy of his portraits. He was born in Carpentras, near Avignon, into a family with an artistic bent and received his first training from his father, a surgeon and talented amateur, then with Joseph-Gabriel Imbert (1666-1749), who had been a pupil of Charles Le Brun. From 1744-47 or later he worked in Rome, in the atelier of Pierre Subleyras, who was also from the south of France, who died in 1749. In Italy Duplessis became fast friends with Joseph Vernet, another Occitan. He returned to Carpentras, spent a brief time in Lyon then arrived about 1752 in Paris, where he was accepted into the Academie de Saint-Luc and exhibited some portraits, which were now his specialty, in 1764, but did not achieve much notice until his exhibition of ten paintings at the Paris salon of 1769, very well received and selected for special notice by Denis Diderot; the Academie de peinture et de sculpture accepted him in the category of portraitist, considered a lesser category at the time. He continued to exhibit at the Paris salons, both finished paintings and sketches, until 1791, and once more, in 1801. His portrait of the Dauphine in 1771 and his appointment as a peintre du Roi assured his success: most of his surviving portraits date from the 1770s and 1780s. He received privileged lodgings in the Galeries du Louvre. In the Revolution, he withdrew to safe obscurity at Carpentras during the Reign of Terror. Afterwards, from 1796, he served as curator at the newly-founded museum formed at Versaillles, so recently emptied of its furnishings at the Revolutionary sales. His uncompromising self-portrait at this time of his life is at Versailles, where he died.
