Consumption Trends, Trading Patterns and Economic Development in Italy Across Centuries: Data Analysis of Roman Amphorae in a Long-Term Perspective

Abstract

This paper presents novel insights into the long-term chronological patterns related to the distribution and consumption of amphora-borne foodstuffs in Italy. The study specifically focuses on the consumption of wine, olive oil and fish sauces, which exhibit diverse provenances. Notably, it contributes significantly to our understanding of the Roman economy by utilising an open dataset and a replicable research method. The analysis reveals a pronounced growth pattern during the late Republican to early Imperial period. Importantly, quantitative evidence demonstrates that the diverse consumption pattern observed in the capital city of Rome is less exceptional than previously believed. The study draws upon a substantial dataset comprising 28,851 diagnostic amphora fragments excavated and documented from 28 different urban and rural settlements in the North Adriatic and Central Italy, spanning the period from the 4th c. BCE to the 7th c. CE. The analytical approach employs a probabilistic aoristic method, evenly distributing amphora frequencies across relevant date ranges.
