The Greeks received from the Thracians and assimilated to their own purposes the worship of Dionysos, just as, in all probability, they received the personality and worship of Ares and the Muses. Of this assimilation we cannot give any further particulars; it took place in a period lying before, the beginnings of historical tradition. In this period a multiplicity of separate tendencies and conceptions, freely mingled with features borrowed from foreign creeds, were welded together to form the religion of Greece.
