There is another group of blue and white which can be definitely assigned to this period of dynastic transition, between 1620–1662. A comparative study of the various blue and white types had already led to the placing of this ware in the middle of the seventeenth century, and Mr. Perzynski, in those excellent articles[211] to which we have already alluded, has set out the characteristics of this ware at some length, with a series of illustrations which culminate in a dated example. There will be no difficulty in finding a few specimens of this type in any large collection of blue and white. It is recognised by a bright blue of slightly violet tint under a glaze often hazy with minute bubbles, which suggested to Mr. Perzynski the picturesque simile of “violets in milk.” Other more tangible characteristics appear in the designs, which commonly consist of a figure subject--a warrior or sage and attendant--in a mountain scene bordered by a wall of rocks with pine trees and swirling mist, drawn in a very mannered style and probably from some stock pattern. Other common features are patches of herbage rendered by pot-hook-like strokes, formal floral designs of a peculiar kind, such as the tulip-like flower on the neck of Fig. 4 of Plate 82; the band of floral scroll work on the shoulder of the same piece is also characteristic. In many of the forms, such as cylindrical vases and beakers, the base is flat and unglazed, and reveals a good white body, and European influence is apparent in some of the shapes, such as the jugs and tankards. As for the dating of this group, an early example of the style of painting in the Salting Collection[212] has a silver mount of the early seventeenth century, and a tankard of typical German form in the Hamburg Museum has a silver cover dated 1642.[213] There is, besides, a curious piece in the British Museum, the decoration of which has strong affinities to this group. It is a bottle with flattened circular body and tall, tapering neck, with landscape and figures on one side and on the other a European design copied from the reverse of a Spanish dollar, and surrounded by a strap-work border. The dollar, from a numismatic point of view, might have been made equally well for Philip II. (1556–1598), Philip IV. (1621–1665), or Charles II. (1665–1700), but there can be little doubt from the style of the ware that it belonged to one of the two earlier reigns. A comparison of the ware and the blue of this group leads to the placing of the fairly familiar type illustrated by Figs. 3 and 5 of Plate 82 in the same intermediate period, and similarly certain specimens of polychrome, with underglaze blue and the usual enamels, display the characteristic body and blue painting, and even some of the decorative mannerisms. These specimens, particularly when of beaker form, are often finished off with a band of ornament engraved under the glaze. [Illustration: Plate 82.--Late Ming Porcelain.
