These three volumes deal with the Iron Age grave materials from Magdalenska gora, excavated by the Duchess Paul Friedrich von Mecklenburg-Schwerin. The Duchess of Mecklenburg, a member of an Austrian royal family with estates in Slovenia, conducted her excavations in the early years of the twentieth century. The materials from Magdalenska gora were purchased by the Peabody Museum in the 1930s. Volume I presents data and analysis of the horse remains and human skeletal materials.
