A possible Roman Period sword from Grzybowo (Grzybowen), Masuria, NE Poland. The archaeological and technological context

The paper discusses a recent stray find of a sword fragment with a possible stamp from Masuria in NE Poland. It was found close to a Roman Period cemetery of the Bogaczewo Culture. On typological grounds, the sword can be classified as a Roman Period weapon. However, the results of metallographic examinations suggest that the find may have been made either from very clean bloomery steel (or hypoeutectoid crucible steel) or from mass-made Industrial Age steel (Bessemer, Thomas, Siemens-Martin, etc.). On the other hand, the chemical composition of the sword would rather imply a pre-Industrial Period steel. In conclusion, it is carefully suggested that the weapon may be a genuine Ancient sword, although its final recognition as a Roman Period weapon could only be verified by finds made from similar metal in undoubted Roman Period contexts.
