This paper is a preliminary exploration of how identity may have been expres- sed in the mortuary rituals around the Baltic during the Mesolithic. The case- studies discussed are the large cemeteries at Skateholm in Sweden, Zvejnieki in Latvia and Vedbæk/Bøgebakken in Denmark. Besides the often discussed variability and complexity recognized in the mortuary practices at these sites, the treatment of the dead also encompasses a number of fundamental shared practices involving the treatment of the body. In this paper, which builds on a practice theory view of both ritual and identity, the author proposes that by ex- ploring the taken-for-granted, the fundamental and often unreflected practices in the treatment of the dead, we might be able to get at some dimensions of a shared identity around the Baltic and how they might have changed over time.
