In late March, 3,000 ancient Buddha statues were found in Handan, China, and archaeologists say that these statues were around 1,500 years old. The Buddha statues were made from white marble and limestone and many statues were broken. The archaeologists say that these statues may date back to the Eastern Wei (AD 534-550) and Northern Qi (AD 550-577) dynasties.
The statues were found outside Ye, the ancient capital of Eastern Wei and Northern Qi dynasties. These statues may have been rounded up and buried by the Northern Qi emperors after the fall of the Northern Qi dynasty, in a attempt to purge the country into Buddhism.
The director of the Center for the Art of East Asia at the University of Chicago, Katherine Tsiang, said that these statues maybe ruins and broken sculptures from the past and gathered from old temple sites and buried in a pit.
I think that this picture shows the concept of Causation. These statues may have been buried by temple officials, because they did not want the statues to be destroyed. As a consequence, thousand years later, the archaeologist unearthed them and we can see them.
