 Tacitus in his ""Germania"", describes their homeland as being where the Elbe starts, but also having colonies at the Danube and even within the Roman province of Rhaetia.Claudius Ptolemy mentions neither the Hermunduri nor the Thuringians in his geography but instead the Teuriochaemae (Turones, see list of ancient Germanic peoples and tribes), living in just north of the Sudetes mountains, thought to be the Erzgebirge.These may also be connected to later Thuringians.
