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 :. | Unfinished painting of St. Jerome in the Wilderness | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | Studies of children | Mona Lisa | Madonna with the Yarnwinder tw |

French Academic Painter, 1811-1847, French painter. He painted his first landscapes and family portraits at Thiers and in the Auvergne before moving to Paris in 1829. After working as the pupil of Camille Roqueplan he was engaged by Baron Karl von H?gel for an expedition to the Near East (1831-3), from which he brought back numerous studies. He visited Greece, Syria, Lebanon and Palestine, stayed in Egypt from October 1831 to May 1833 and returned by way of Rhodes and Corfu. Cairo, the villages of the Delta and Upper Egypt proved to be sources of inspiration for later works.

Nicolaes Pietersz. Berchem
(1 October 1620 - 18 February 1683) was a highly esteemed and prolific Dutch Golden Age painter of pastoral landscapes, populated with mythological or biblical figures, but also of a number of allegories and genre pieces. Born in Haarlem, he received instruction from his father Pieter Claesz, and from the painters Jan van Goyen, Pieter de Grebber, Jan Baptist Weenix, Jan Wils and Claes Cornelisz. Moeyaert.According to Houbraken, Carel de Moor told him that Berchem got his name from two words "Berg hem" for "Save him!", an expression used by his fellows in Van Goyen's workshop whenever his father chased him there with the intent to beat him. No trip or Grand Tour by Berchem was documented by Houbraken though he mentioned another story about the "Berg hem!" nickname which came from Berchem's conscription as a sailor; the man in charge of impressment knew him and sent him ashore with the words "Save him!".Today his name is assumed to come from his father's hometown of Berchem, Antwerp. According to the RKD he traveled to Italy with Jan Baptist Weenix, whom he called his cousin, in 1642-5. Works by him are signed both as "CBerghem" and "Berchem".
