The Stone Classics are a collection of stone carved books on various Confucian classics.
The stelae that were elaborated over an eight year period (AD 175 to 183) during Han dynasty (BC 206 to AD 200) contained 200,000 characters across 46 stelae. They covered the seven classics recognized at the time: the Book of Changes, Book of Documents, Book of Songs, Book of Rites, Spring and Autumn Annals, Classic of Filial Piety and Analects. Each stelae was about 2.5 meters high and 1 meter wide.
The Stone Classics of Han dynasty were mostly destroyed in the fighting following the collapse of the Han dynasty in 207, and only a few fragments have survived. They were the first of several enterprises through history that tried to provide correct and authoritative versions of the classics texts.
