In October 1915 there was discovered near the small village of Guiry, 50 km. north-west of Paris, an example of the typical Paris Basin Gallery Grave or Allée Couverte. It came to be known as the Allée Couverte du Bois Couturier, and is a relatively small example of this type of tomb which predominates in the departments of Seine-et-Oise and Oise, and extends eastwards into neighbouring departments. The grave-goods belong mainly, though not exclusively, to the Seine-Oise-Marne culture as first defined by Bosch-Gimpera and Serra Rafols [I]. Daniel regarded the Paris Galleries as dating probably from about 1700-1400 B.C.; Bailloud, on the basis of certain radiocarbon dates available since Daniel's study, considers the SOM culture (which is of course not necessarily completely coeval with the Paris Galleries) to have begun around 2400-2300 B.c., and to have ended around 1700-1600 B.C.
