The aim of this article is to assess the value of Marija Alseikaitė-Gimbutienė’s (Gimbutas) 1946 dissertation published in Tübingen (Germany). It is also important to follow how much of an impact this work had on Lithuanian archaeology and what inspiration it may provide for scholars today. This paper concentrates on the parts of the book which deal with burial customs during the Roman Iron Age. Relevant problems of cultural divisions based on burial site types as per Gimbutienė are examined to see how much this classification may be accepted today. The second part of Gimbutienė’s dissertation, which focused on the meaning of burial customs, provides insights that are still important for scholarship today, and reveals the young scholar’s ability to reconstruct an old belief system and to discern the prospects for the further investigation of burial site material.
