Pb isotope data of Roman and medieval objects from Wiesloch near Heidelberg, Germany

Lead isotope abundance ratios have become a reliable and common tool for obtaining information on the provenance of archaeological material containing lead. This paper presents Pb-isotope data of lead-silver smelting relics dating to the High Middle Ages, data from Roman objects, as well as data from objects of various other periods from Wiesloch and the surrounding area. The results are compared to Pb-isotope data from the Wiesloch Pb-Zn deposit and some Rhenish lead deposits. Results indicate that during the Roman period, only local lead was used at Wiesloch, while during later periods, lead from other sources is also present.
