Museum collections of documented but unpublished archaeological material often constitute excellent sources of primary archaeological data. The Duchess of Mecklenburg excavated extensively at Iron Age cemeteries in Slovenia, in what is now part of Yugoslavia, just before the First World War. Her collection, which is now being published, provides hundreds of well-documented grave groups for study. This article considers her work at the site of Sticna and is concerned particularly with the graves containing weapons excavated at that site.
