Knotenringe from Wolin. A new pre-Roman site or a result of the secondary use of metal in the early Middle Ages?

The paper presents an analysis of a ring with knot-like protuberances (Knotenringe) made of copper alloy which was discovered in 2000 at the early medieval settlement at Wolin 4. A few artefacts of this type are known from sites of the Oksywie and Przeworsk cultures, dated to phases A2–A3 of the younger pre-Roman period. Their presence is linked to the influence of Celtic oppida in Slovakia. The discovery of the ring on an early medieval settlement with no relation to older settlement gives grounds to consider it as a result of recycling and attempts to reuse the raw material
