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 :. | The Virgin of the rocks | The Virgin and Child with St Anne | The organs of the woman | Annunciation (detail) ey79 | Mona Lisa (detail) dyk |

Jeronymus van Diest
(1631, The Hague - ca.1687, The Hague), was a Dutch Golden Age seascape painter. According to Houbraken, a Jeronymus van Diest was good with grisailles and was the teacher of Adriaen van de Venne.[1] This grisaille painter Jeronymus Diest (I) may possibly have been a grandfather of the younger Jeronymus Diest (II); since they are both from the Hague. According to the RKD this younger Jeronymus Diest (II) was the son of the painter Willem van Diest and the father of the painter Adriaen van Diest who was a follower of Jan van Goyen and Hendrik Dubbels.His known works are all seascapes with various ships at sail.
Hyacinthe Rigaud
1659-1743 French Hyacinthe Rigaud Gallery He was born Jacint Rigau i Ros [1] -- though in many encyclopaedias is "re-christened" with the name of H??acint Francesc Honrat Mathias Pere Martyr Andreu Joan Rigau -- in Perpignan, which became French (Treaty of the Pyrenees) a short time after his birth (November 7, 1659). In 1682, he was awarded the Prix de Rome. He was the most important portrait painter in the reign of King Louis XIV. His instinct for impressive poses and grand presentations precisely suited the tastes of the royal personages, ambassadors, clerics, courtiers, and financiers who sat for him. Because Rigaud's paintings captured very exact likenesses along with the subject's costumes and background details, his paintings are considered precise records of contemporary fashions. Rigaud was a master of the Baroque style of art. Rigaud's best-known work is his 1701 painting of Louis XIV which today hangs in the Louvre in Paris, as well as the second copy also requested by Louis XIV which is now at Versailles. In 1709 he was made a noble by his hometown of Perpignan. In 1727 he was made a knight of the Order of Saint Michael. Hyacinthe Rigaud died in Paris, France on December 27, 1743.
