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.

(Amsterdam, 1621- Vleuten 1660), a painter of the Dutch Golden Age. Despite his relatively brief career, he was a very productive and versatile painter. His favourite subjects were Italian landscapes with large figures among ruins, seaside views, and, later in life, large still life pictures of dead game or dogs. He was mainly responsible for introducing the Italian harbour scene into Dutch art, in mid-size paintings with a group of figures in the foreground.
Weenix was the son of an architect and born near Amsterdam's harbour. He could not speak well, apparently from a medical condition, and because he very much liked to read books, his mother sent him to work for a bookseller, who was not able to deal with him. He drew whenever he could, according to Jan Weenix his son, who told the story to Arnold Houbraken.
Weenix first studied under Jan Micker, then in Utrecht under Abraham Bloemaert, and later back in Amsterdam under Claes Cornelisz. Moeyaert. In 1643 Weenix travelled to Rome with Nicolaes Pieterszoon Berchem. He had left his home secretly, but his wife, the daughter of Gillis d'Hondecoeter, traced him to Rotterdam. Then he was allowed to stay away for four months. In Rome he became a member of the Bentvueghels and was much esteemed and worked for Pope Innocent X. He returned to Amsterdam after four years; his wife had refused to come to Rome.
In 1649 he became master of the guild of St. Luke in Utrecht and also painted a portrait of Rene Descartes. When his brother-in-law Gijsbert d'Hondecoeter died, he trained his nephew Melchior d'Hondecoeter, together with his own son Jan Weenix. Weenix moved to a castle outside Utrecht, to concentrate on his work or for health reasons, where he probably died in poor circumstances, at an unknown date.
He painted a few religious scenes, one of the rare pieces of this kind being the "Jacob and Esau" (Gemäldegalerie Alte Meister, Dresden). In the National Gallery, London, is a "Hunting Scene" by Weenix, and Glasgow has a characteristic painting of ruins. Weenix is represented at most of the important continental galleries, notably at Munich, Vienna, Berlin, Amsterdam, and St Petersburg.
