His etchings are much prized. One of the most famous represents Christ healing the sick, and is called the "Hundred Guilders Print," because that sum was the price he fixed for it; now a good impression of it is worth ten times as much. At his death he left about six hundred pictures and four hundred engravings. His landscapes are his rarest subjects. Most of these are in private collections, but I have seen one in the Cassel Gallery; the color of it is bright and glowing--the sky magnificent. In the foreground there is a bridge, and on an eminence are the ruins of a castle. Some fine works by Rembrandt are in England, and very large prices have been paid for them. In 1867 "Christ Blessing Little Children" was sold for seven thousand pounds. At the San Donato sale in Florence, in 1880, "Lucretia" brought twenty-nine thousand two hundred dollars, and a "Portrait of a Young Woman" nearly as much. Among Rembrandt's pupils Gerbrandt van der Eeckhout holds a high rank, and his pictures are seen in many galleries. Among the landscape painters of Holland ALBERT CUYP (1605-1691) is very famous. He sometimes introduced figures and animals into his pictures, but they were of secondary importance; the scenery was his chief thought. His works are in many galleries, and the increase in their value is marvellous. Sir Robert Peel bought a landscape, twelve by twenty inches in size, for which he paid three hundred and fifty guineas: it was originally sold in Holland for about one English shilling! During the first century after his death no picture by Cuyp brought more than thirty florins; now they cost almost their weight in gold. Other fine landscape painters were Jan and Andries Both, Jan van Goyen, Jan Wynants, Adrian van de Velde, and, finally, PHILIP WOUVERMAN (1619-1668), who introduced much life into his works. He painted battles, hunting parties, and such subjects as allowed him to introduce white horses, for which he became noted. His works, as well as those of the other painters last mentioned, are valuable. There are so many in galleries which are attributed to Wouverman that it is doubtful if they are all genuine. He had animation and fine feeling for the picturesque. His execution was light and delicate, and there is much tenderness shown in his works. There were many excellent Dutch landscape painters whom we have not mentioned. PAUL POTTER (1625-1654) was born at Enkhuysen, and though he died young he made himself a great and enduring reputation by his pictures of animals. "Paul Potter's Bull," which is in the gallery at the Hague, is as well known as any one picture the world over. He left one hundred and eight pictures and eighteen etchings. He was most successful in representing cattle and sheep; his horses are not as fine. He never crowded his pictures; they have an open landscape, but few animals, and perhaps a shepherd, and that is all. Some of his pictures have been valued as high as fifty thousand dollars.
