The discovery is believed to be the largest of its kind since the founding of the People's Republic of China in 1949, an archaeologist with the Chinese Academy of Social Sciences told reporters in late March, according to the Associated Press.
The Buddha statues—most of which are made of white marble and limestone and many of which are broken—could date back to the Eastern Wei and Northern Qi dynasties (A.D. 534 to 577), experts say.
The statues—discovered during a dig outside of Ye, the ancient capital of the Eastern Wei and Northern Qi dynasties—may have been rounded up and buried after the fall of the Northern Qi dynasty by later emperors in an attempt to purge the country of Buddhism.
"It may have been that some of the ruins and broken sculptures from the past were gathered from old temple sites and buried in a pit," said Katherine Tsiang, director of the Center for the Art of East Asia at the University of Chicago.
In some cases, the Buddhist statues may have been buried by the faithful themselves in times of danger.
"In other sites, there are inscriptions that suggest that old damaged sculptures were not just dumped in a pit, but respectfully buried in an orderly way," Tsiang said.
