This group encompassed a federation of Alpine tribes, including the Calucones, for about 6 centuries starting around 500 BC.  
Calucones: The Calucones were a Rhaetian tribe mentioned by a few of the classical sources, but not all. Calucones:  Pliny the Elder (Book 3 Chapter 24 of Naturalis Historia, published in 77 CE) quotes a monument to the reign of Augustus, the tropeaum Alpium, located in the Rhaetia of his day, stating that Augustus subdued the Alpine peoples from the upper sea to the lower sea, including the Calucones. Rhaetian people: The Raeti (spelling variants: "Rhaeti", "Rheti" or "Rhaetii"; Ancient Greek: "Ῥαιτοί": transcription "Rhaitoí") were a confederation of Alpine tribes, whose language and culture may have derived, at least in part, from the Etruscans. Rhaetian people:  From not later than ca. 500 BC, they inhabited the central parts of present-day Switzerland, the Tyrol in Austria, the Alpine regions of northeastern Italy and Germany south of the Danube.
