Ptolemy, however, mentions the Lougoi Bouroi (transliterated by the scholars into Latin Lugi Buri) dwelling in what is today southern Poland between the Elbe, the modern Sudetes, and the upper Vistula. They are distinct from the Silingi (Vandals), who are on the upper Oder. Tacitus and Ptolemy together imply that the Buri may have entered Moravia from Suebia with the Marcomanni and Quadi and then moved into the upper Vistula region, where they allied themselves with the Lugii there.
