Studies to the norican-pannonian barrows. Focus on Styria. The presented work deals with the phenomenon of barrows, particular with the norican-pannonian round barrows, which occur as funeral custom during the Roman period predominantly in the border area between Noricum and Pannonia and develop diverse grave and construction forms from the ongoing 2nd century AD. They and those barrows, which appear almost at the same time in other provinces, are associated with Romanization and its processes and can also show how local individuals or groups were resettled within the province or the Roman Empire. This is indicated by certain findings like n.-p. costume constituents, Dreifußschalen or Einknotenfibel as well as by epigraphic documents like grave or dedicatory inscriptions. Latter suggest, that various population strata (freed and indigenous peoples, soldiers, veterans, public officials) were buried beneath or within barrows and that their size and equipment depends in case to case on the social status of the deceased and their family remaining behind. Special those barrows, that are large in size, have rich grave equipment and an external stone ring, differ from the n.-p. barrows, because they were built by immigrated rich merchant families and are definitely linked, as the provincial round graves (tumuli), to italian-mediterranean models. In contrast to them the origin of the n.-p. barrows is attributed more to the local natives (non-norican). In her work the author tries to summarize how complex this topic can be and which research problems and theories are in context with the barrows. In order to check the assumptions of E. Hudeczek concerning the question of origin and to determine a current picture about the research state, chronological and architectural facts from the styrian barrows were collected and under the aspect of distribution evaluated.
