Mr. Croyden took a pull at his pipe. "Much of their design was symbolic, and much of the coloring they used had a national significance. For example, the Dragon was a symbol of empire and power; the Dog, a sacred animal, was often used; but it was no ordinary dog. Instead it had great teeth, a curling mane, and claws like a lion. A Chinese artist would have scorned to copy a real dog, for that would not have been considered art; nor would a picture of any living type of dog be half as imposing as was this imaginary creature with its fierce teeth, mane, and claws. Sometimes the _Kylin_, a sort of stag with a dragon's head, and a symbol of good-fortune, was used. There were many other of these symbolic designs employed to enhance the beauty of Chinese porcelains, and of course to the Chinese each one had its meaning." "It is an interesting idea, isn't it?" Theo said slowly. "Very; and makes much of our own art seem pitifully thin. And when you consider that the colors the Chinese used also had their meaning, as did various geometric forms introduced, you can readily see how much one must study to understand Chinese--and for that matter, Japanese art; for the Japanese used much the same methods in decorating their potteries and porcelains, although of course their symbolism varied. With the Chinese green and vermilion were colors sacred to the wall decorations of Emperors' houses; red typified fire; black, water; green, wood; white, metal. Fire was also sometimes represented by a circle, and the earth by a square. All this I tell you that you may see how much thought went into everything they did. In addition certain objects were made for especial purposes, and decorated in accordance with their use. There were drinking cups for poets, authors, and government officials, each cup having an appropriate picture in the bottom. Then there were incense-burners, vases, bowls, and vessels for libations at ceremonials; there were, too, statues of the various gods. Besides these many types of workmanship the Chinese made a very thin egg-shell porcelain, the most fragile and transparent of which we now get from Japan; and a porcelain decorated with a fine, open-work design cut through the ware, and styled 'grains-of-rice pattern.' Moreover they manufactured a variety which in firing took on a crackled effect and has for that reason been christened Chinese Crackle. You see how many kinds of thing they worked out." "I should say so!" exclaimed Theo.
