Olive Oil at the Border of the Roman Empire. Stamps on Baetican Dressel 20 found on the Tyne-Solway Isthmus

Abstract

This paper focuses on Dressel 20 stamps found on the Tyne-Solway isthmus and Hadrian's Wall from the first to the fourth century AD. The aim is to describe olive oil imports to the limes of Britannia by focusing on the distribution of stamps along the wall, their location and the most common stamp dies. This research also provides an accurate analysis of olive oil exportation by studying the workshops (figlinae) where these stamps were produced, and by describing the economic activity of figlinae from a chronological and administrative standpoint.
