Practically nothing is known of the social organization or religious beliefs of the people who erected the menhirs. We have no trace even of these peoples' language, however we do know that they buried their dead, and had the skills to grow cereal, farm, and make pottery, stone tools, and jewelry. Speculation as to their use remains speculation, however it is likely that many had a functionality involving fertility rites and seasonal cycles. Until recently, menhirs were associated with the Beaker people, who inhabited Europe during the later third millennium BC; the European late Neolithic and early Bronze Age. However, recent research into the age of megaliths in Brittany strongly suggests a far older origin, perhaps back to six to seven thousand years ago
