The enigma of the Great Menhir

7,000 years ago, the people of the Atlantic Coast erected thousands of megaliths, on which they carved mysterious signs. An international team of scientists, led by the Frenchman Serge Cassen, based on the great menhir of Er Grah (Brittany), has explored many of these gigantic constructions and has reached the conclusion that they contain a symbolic language, carved in stone.
