We are in the dark even now as to the date and place of origin of more than one class of Oriental porcelain. On the question of the relation of the ceramic wares of China to the contemporary sister arts, there are many points to be cleared up,--I mean especially the question how far the early wares were influenced by the art of the bronze-caster and the carver of jade, and again to what extent the decoration of porcelain in later times was dependent upon the example of the contemporary schools of painting. When we know about the pictorial art of the Chinese even the little that we do already of that of their Japanese neighbours, we shall, to give but one instance, be able to trace the source of the beautiful landscapes and flower designs that we find on the vases and plates of the _famille verte_ and _famille rose_. There is one source of information which remains as yet almost completely untapped. The Japanese have been for many centuries keen collectors of Chinese porcelain, as of other Chinese objects of art. They have their own views on its history, and some of the finest specimens of the older wares remain still in Japan, in spite of the many pieces that have of late years been carried away to Europe and America. As we shall see, they have in their own pottery and porcelain handed on to quite recent days many traditions of Ming and earlier times that have been lost in China. If some Japanese connoisseur or antiquary, strong in Chinese lore, could give us a history of porcelain from his own point of view, I think that European investigators would have cause to be grateful. Much could be gleaned, as I have already said, by studying the relation of the potters art to that of the jade-carver and the caster of bronze, and this brings us to an important point that perhaps has not been fully appreciated by us in the West. I refer to the comparatively late date of the beginning of porcelain in China compared, for example, to the arts just mentioned. We can hardly carry back the history of true porcelain beyond the great Tang dynasty (618-907 A.D.), and even in China there is no existing specimen that can safely be attributed to so early a date. But this same Tang dynasty was the very heyday in that country, not only of military power but also of artistic culture. It would be impossible to enter into this important subject here; it is one that has been strangely ignored by us in Europe. Suffice to say that the great figure-painters of this period were looked back to with veneration in later times, both in China and in Japan, and that the two schools of landscape, the colour school of the North and the black and white ‘literary’ school of the South--schools whose traditions have survived to the present day--were both founded by Tang artists. At that time art critics were known (and even honoured); they already wrote books on the early history of painting, and they have left us descriptions of famous collections.
