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 :. | Madonna with the Yarnwinder | Hl.

ES, Jacob van
Flemish painter (b. ca. 1596, Antwerpen, d. 1666, Antwerpen) Flemish painter. Together with Osias Beert and Clara Peeters, he was one of the leading representatives of the archaizing trend in Flemish still-lifes. His birthplace is known from the text on an engraving by Wenceslaus Hollar after a painting by Jan Meyssens (1612-70). Van Es became a master in Antwerp in 1617 but did not join the Guild of St Luke until 1645. Jacob Gillis and Jan van Thiene were his pupils in 1621 and 1623 respectively. He enjoyed a certain esteem among fellow artists, for Jacob Jordaens, Cornelis Schut the elder and Deodaat del Monte were godfathers to his children. Numerous mentions of works by van Es in inventories of 17th-century Antwerp collectors further testify to his success

Johan Thorn Prikker
1868-1932 Dutch Johan Thorn Prikker Gallery Dutch painter, printmaker, mosaicist and stained-glass artist. He attended the Koninklijke Academie van Beeldende Kunsten in The Hague (1881-8). During this period he painted mainly landscapes in the style of The Hague school. Until c. 1896 he produced Symbolist works, in which the emphatic line flow and the subtle colour shading are especially noticeable, for example The Bride (1893; Otterlo, Kr?ller-M?ller). From 1892 until 1897 he corresponded with Henri Borel, partly about his Symbolist work, often drawing in the letters. During this time he came into close contact with Belgian artists, in particular with Henry Van de Velde through whom he was able to exhibit with Les XX in Brussels. In summer he regularly stayed in Vise, where he produced pastel drawings in a rhythmic pointillism, a style with which he could achieve a form of abstraction.
