DOUW, or Dow, GEREIARD (1613-1680), a celebrated Flemish painter, was born at Leyden on the 7th April 1613. 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 fifteen he became a pupil of Rembrandt, with whom he continued for three years. From the great master of the Flemish school he acquired his skill in colouring, 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 twenty-two, in the Bridgewater Gallery, and in the Blind Tobit going to meet his Son, at Wardour Castle.

a comparatively early point in his career, however, he had fonned a manner of his own distinct from, aud indeed in some respects antagonistic to, that of his master. Gifted with unusual clearness of vision and precision of manipula-tion, 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 dow-n 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 colour was always admirably fresh and transparent. He was fond of representing subjects in lantern or candle light, the effects of which lie reproduced with a fidelity and skill which no other master has equalled. 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 two hundred are attri-buted to him, and specimens are to be found in most of the great public collections of Europe. His chef ceceuvre is generally considered to be the Woman sick of the Dropsy, in the Louvre. The Evening School, in the Amsterdam Gallery, is the best example of the candle-light scenes in which lie excelled. In the National Gallery favourable specimens are to be seen in the Poulterer's Shop and a portrait of himself. Douw's pictures brought high prices, and it is said that President Van Spiting of the Hague paid him 1000 florins a year simply for the right of pre-emption. Douw died in 1680. His most celebrated pupil was Francis Miens.
