The Beifudi (北福地) prehistoric site, near Yi County in Hebei Province, China, is the excavation of a recently discovered prehistoric Neolithic village that Chinese archaeologists say is one of the most important sites found so far. The site, an area of 3 ha on the northern bank of the Yishui River, contains artifacts of a culture contemporaneous with the Cishan and Xinglongwa cultures of about 7000–8000 BP, two known Neolithic cultures east of the Taihang Mountains, and thus fills an archaeological gap between the two Northern Chinese cultures. The total excavated area is more than 1,200 square meters and the collection of neolithic findings at the site has been conducted in two phases.
This archaeological site was voted Number One in the Top Ten most outstanding archaeological findings in 2004 by Chinese archaeologists in their annual poll.
The most significant discovery in the first phase of the site's excavation is the large number of pottery masks in the shape of human and animal faces, the oldest extant carvings to date. A dozen carved clay masks, in cat, monkey and pig as well as human likenesses, have been unearthed at Beifudi. One mask of a human face has a mouth and nose in carved relief and the eyes are pierced out. The first engraved clay artifacts ever found in ruins of this age, the masks add several millennia to China’s history of carving.
These artifacts, along with raised platforms, or altars, may provide information on various early religious practices. Although the beliefs of these Neolithic people are not known, the early Chinese almost certainly performed ritual ceremonial sacrifices and burned burials (fanyi) on the raised platforms, as both human and animal burials have been found. The masks are believed to be part of the ritual performances accompanying sacrifices and burials.
