Measurements: Quern length: 68cm, Height: 6cm, Roller length: 58cm

This stone quern and roller set was used for processing crops. They were unearthed at the Peiligang culture site at Xinzheng, which dates back to about 8,000 years ago. They indicate that agriculture in that period had already separated itself from the "slash-and-burn" phase, and had entered the stage of hoe-cultivation.

Multiple sets of stone querns and rollers have been discovered at the Peilingang site, with this particular set standing out as the best-preserved and showcasing finer craftsmanship. 

Crafted from a sizable sandstone block, the quern is fashioned in the shape of a shoe sole with a smooth and flat surface supported by four column-shaped feet. The roller is easy to grip, and bears visible traces of past usage.
