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 Madonna of the Carnation (detail) sg | Lorenzo de Medici between Antonio Pucci and Francesco Sassetti, with Giulio de Medici, fresco by Ghirlandaio | Battle of Anghiari | Study of an apostle | Buste one frontal to seeing man and head of a Lowen |

Dutch Baroque Era Painter, 1652-1700,Son of Thomas Wijck. A marriage certificate issued on 22 November 1676 describes the artist as 'Jan Wick of St Paul's Covent Garden, gent., widower, about 31 ...', suggesting that he was born c. 1645, but his correct birthdate is known from the inscription on a mezzotint portrait of him by John Faber II (1684-1756) after a painting by Sir Godfrey Kneller. Jan is first documented on 17 June 1674, when he appeared before the court of the Painter-Stainers' Company in London and vowed to pay both his own and his father's quarterly fees. The certificate of 1676 relates to his second marriage, to Ann Skinner (d 1687), who between 1678 and 1683 bore him four children, all of whom died young. After Ann's death in 1687, he married Elizabeth Holomberg (d 1693) in 1688 and moved to Mortlake. Between 1689 and 1693 they had two sons and a daughter.

Gerard Dou
Leiden 1613-1675 was a Dutch Golden Age painter, whose small, highly-polished paintings are typical of the Leiden fijnschilders. He specialised in genre scenes and is noted for his trompe l'oeil "niche" paintings and candlelit night-scenes with strong chiaroscuro. His first instructor in drawing and design was Bartholomew Dolendo, an engraver; and he afterwards learned the art of glass-painting under Peter Kouwhoorn. At the age of 15 he became a pupil of Rembrandt, with whom he continued for three years. From the great master of the Dutch school he acquired his skill in coloring, and in the more subtle effects of chiaroscuro; and the style of Rembrandt is reflected in several of his earlier pictures, notably in a portrait of himself at the age of 22, in the Bridge-water House gallery, and in the "Blind Tobit going to meet his Son", at Wardour Castle. At a comparatively early point in his career, however, he had formed a manner of his own distinct from, and indeed in some respects antagonistic to, that of his master. Gifted with unusual clearness of vision and precision of manipulation, he cultivated a minute and elaborate style of treatment; and probably few painters ever spent more time and pains on all the details of their pictures down to the most trivial. He is said to have spent five days in painting a hand; and his work was so fine that he found it necessary to manufacture his own brushes. Notwithstanding the minuteness of his touch, however, the general effect was harmonious and free from stiffness, and his color was always admirably fresh and transparent. He was fond of representing subjects in lantern or candle light, the effects of which he reproduced with a fidelity and skill which no other master has equaled. He frequently painted by the aid of a concave mirror, and to obtain exactness looked at his subject through a frame crossed with squares of silk thread. His practice as a portrait painter, which was at first considerable, gradually declined, sitters being unwilling to give him the time that he deemed necessary. His pictures were always small in size, and represented chiefly subjects in still life. Upwards of 200 are attributed to him, and specimens are to be found in most of the great public collections of Europe. His chef-d'oeuvre is generally considered to be The dropsical woman, 1663, and The Dutch Housewife, 1650, both in the Louvre. The Evening School, in the Amsterdam Rijksmuseum, is the best example of the candlelight scenes in which he excelled. In the National Gallery, London, favorable specimens are to be seen in the Poulterer's Shop,
