Ver sacrum

Ver sacrum ("sacred spring") is a religious practice of ancient Italic peoples, especially the Sabelli (or Sabini) and their offshoot Samnites, concerning the dedication of colonies. It was of special interest to Georges Dumézil, according to whom the ver sacrum perpetuated prehistoric migration practices of Indo-Europeans to the end of the Iron Age and into the beginnings of history, when stable sedentary dwelling conditions had already become general.
