Bannerstone
From Wikipedia, the free encyclopedia
Bannerstones are artifacts usually found in the Eastern United States that are characterized by a centered hole in a symmetrically shaped carved or ground stone. The holes are typically ¼” to ¾” in diameter and extend through a raised portion centered in the stone. They usually are bored all the way through but some have been found with holes that extend only part of the way through. Many are made from banded slate or other interestingly colored hard stone. They often have a “wing nut” or “butterfly” shape but are not limited to these.
Archaeologists have agonized for a long time over the use of banner stones. Some have offered that they are atlatl weights or ceremonial pieces. Others have suggested that they are for drilling, cordage making, or fire making. Robert S. Berg’s theory proposed that they are part of a kit of tools used to make and repair atlatl darts. Berg’s theory has met with a lot of skepticism and resistance because of the previous works of William S. Webb, who proposed that the bannerstone was actually part of an atlatl. Webb sited “in situ” evidence which consisted mainly of bannerstones found in line with atlatl handles and hooks in graves that archaeologist dug up during the construction of the Tennessee Valley Authority’s massive water control system in the southeast during the early part of the 20th Century.
