Until the 1970s, linking archaeological data to historical events documented in the literary sources was a common approach in archaeological studies. Despite its limitations this method is still frequently used. There are many interpretations of the consequences of the migrations of the Cimbri and Teutones, which according to some texts swept Europe at the end of the 2nd century BC. One of these consequences would be the settlement of the Helvetii on the Swiss Plateau (CH), the fortification of Manching (DE) and the abandonment of the site of Němčice nad Hanou (CZ).
Let us leave aside the sources and restart the investigation, now without a tunnel vision. Can we really identify and confirm migratory phenomena using coins, by comparing the monetary profiles of sites whose occupation covers the period between 150 and 50 BC? What methodology can we use to differentiate between population movements and trade?
