The Dutch painters carried this still further, particularly in their pictures of interiors and landscapes. It is the atmosphere in the rooms that makes Peter de Hoogh's portrayal of interiors so wonderful. In our little picture the light coming through the window makes the air almost golden. When this painting of air and tone is set forth by the exquisite colour of Peter de Hoogh, you see this kind of Dutch achievement at its best. Cuyp's love of sunshine is rare among Dutch landscape painters. He suffuses his skies with a golden haze that bathes his kin and kine alike in evening light. In our picture you can feel the great height of the sky and the depth of the air between the foreground and the horizon. The rendering of space is excellent. But Cuyp has not been content with the features of his native Holland. He has put an imaginary mountain in the distance and a great hill in the foreground. It is certainly not a view that Cuyp ever saw in Holland with his own eyes. He thought that the mountain's upright lines were good to break the flatness; and the finished composition, if beautiful, is its own excuse for being. [Illustration: LANDSCAPE WITH CATTLE From the picture by Cuyp, in the Dulwich Gallery] Rembrandt is an exception to all rules, but most of the Dutch painters did not allow themselves these excursions within their studios to foreign scenes. They faithfully depicted their own flat country as they saw it, and added neither hills nor mountains. But they varied the lighting to express their own moods. Ruysdael's sombre tone befits the man who struggled with poverty all his life, and died in a hospital penniless. Cuyp is always sunny. In his pictures, cattle browse at their ease, and shepherds lounge contented on the grass. He was a painter of portraits and of figure subjects as well as of landscapes, and his little groups of men and cattle are always beautifully drawn. Ruysdael, Hobbema, and many others were landscape painters only, and some had their figures put in by other artists. Often they did without them, but in the landscapes of Cuyp, cows generally occupy the prominent position. The black and white cow in our picture is a fine creature, and nothing could be more harmonious in colour than the brown cow and the brown jacket of the herdsman. There were some painters in Holland in the seventeenth century who made animals their chief study. Theretofore it had been rare to introduce them into pictures, except as symbols, like the lion of St. Jerome, or where the story implied them; or in allegorical pictures, such as the 'Golden Age.' But at this later time animals had their share in the increased interest that was taken in the things of daily life, and they were painted for their handsome sakes, as Landseer painted them in England fifty years ago.
