Beyond this mountain range (probably the modern Sudetes) where the Marsigni and Buri lived, in the area of modern southwest Poland, Tacitus reported a multitude of tribes, the most widespread name of which was the Lugii. These included the Harii, Helveconae, Manimi, Helisii and Naharvali. (Tacitus does not mention the language of the Lugii.) As mentioned above, Ptolemy categorizes the Buri amongst the Lugii, and concerning the Lugii north of the mountains, he named two large groups, the Lougoi Omanoi and the Lougoi Didounoi, who live between the Suevus river (probably the Saale (Sorb Soława) or Oder river) and the Vistula, south of the Burgundi.
