A 12th‐Century Slavic Ship from Wolin,Poland

Wreck 10 found in Rec?aw, near Wolin, in 2003, is described in detail and the remains are examined to determine whether the vessel they represent was a river ferry, as has been suggested previously, or a medieval seagoing ship, built in the Slav tradition. The location of the wreck is also considered in relation to early medieval settlement in the area to investigate whether it was a harbour.     

Potassium-argon ages of schist honestones from the viking age sites at Kaupang (Norway), Aggersborg (Denmark), Hedeby (West Germany) and Wolin (Poland), and their archaeological implications

Viking age honestones from four large sites in northern Europe have been made from two different types of quartz-muscovite schist: one dark grey, very fine-grained schist, and a light grey, fine-grained schist. In order to determine the provenance of these schist hones, KAr ages have been determined on 16 selected representative hones. The dark grey schist hones yield Caledonian ages of 403–446 Ma. and consideration of petrographic evidence leads to the conclusion that the hones were quarried in the Caledonian area (presumably) of Western Norway. The light grey schist hones are Precambrian, with KAr ages of 931–946 Ma, and are presumed to originate from Telemark, South Norway. The amount and homogeneity of these honestone groups from different parts of the Viking world indicates the existence of large quarries, and demonstrates that production and trade were more wide-ranging than had hitherto been assumed.
