One of a set of three tablets (yuce)

One of the great conceits of the Qianlong emperor (reigned 1736-1795) was to have large numbers of ritual texts and other writings transferred to jade books. The individual "pages" were made of finely finished nephrite plaques of a uniform thickness with a surface usually measuring about 6 by 8 inches. The characters of the texts were cut into the polished surface, often in the writing style of the emperor himself. These pages were created in the fourth year of the Jiaqing emperor's reign.
