 The archaeological Gustow group of Western Pomerania is also associated with the Rugii.The remains of the Rugii west of the Vidivarii, together with other Gothic, Veneti, and Gepid groups, are believed to be identical with the archaeological Debczyn group.In 150 AD, the geographer Ptolemaeus did not mention the Rugii, but he did mention a place named "Rhougion" (also transliterated from Greek as "Rougion", "Rugion", Latinized "Rugium" or "Rugia") and a tribe named the "Routikleioi" in roughly the same area, between the rivers Vidua and Vistula.
