Without going into the extremely complex processes of ethnogenesis of the peoples, I will try to briefly survey the emergence and development of the Baltic cultures in the vast area covered by the Baltic hydronyms for five thousand years and to show the role of sacred stones in a long historical road of the Balts. Neolithic in the lands of the Baltic Sea area started relatively late, in the V millennium. BC. e., and lasted until the middle of the II millennium. BC. e. Stone Age is characterized by matriarchy - the power of mothers. Then the people blessed and revered the Great Goddess elk. We knocked on the stones should be performed magic rituals that ensured success in the hunt. The dead were buried under the fireplace inside the house or near the house. Gone after death were members of the team, protecting kin and helping the living.
