Archaeological sources provide a wide range of information to help understand the social structure of human society in the past. In this paper, the authors deal with the information potential of grave pit modifi cations and wooden structures in graves at burial sites in the central region of Great Moravia (southeast Moravia, southwest Slovakia). The goal at this point is to defi ne the basic hypotheses and describe the methodological basis along with the research methodology. The authors treat the sources holistically, which means that one of the methodological foundations is the claim that the properties of the whole are not a simple sum of its parts. This means that all recognized elements of the funeral rite and their mutual relations and functions are the center of attention of this research. The primary basis for the research is the assumption that the presence of various wooden structures or wooden burial receptacles in the graves of the Great Moravian period is a common cultural occurrence. It further tests the hypothesis that there was intent behind choosing of these different wooden structures and grave pit modifi cations and their usage, as well as a potential differentiation based on age or gender in the frequency, quality and selection of these modifi cations/arrangements and structures. The main methodological tools are statistical and GIS analysis and the results are compared with published fi ndings from the wider Central European region., Marian Mazuch, Marek Hladík., and Obsahuje seznam literatury
