This article uses amphora quantification and regression analysis to trace economic changes in the Mediterranean between the Principate (27 bc to ad 284) and Late Antiquity. It indicates that, during the Principate, there was a clear pattern of amphora distribution across the Mediterranean, which can be explained by the predominance of market forces among the factors governing trade. In contrast, the weak correlation between exports and prices observed in Late Antiquity suggests a significant shift in the underlying principles of trade during this period.
