A study of the Roman iron bars of Saintes-Maries-de-la-Mer (Bouches-du-Rhône,France). A proposal for a comprehensive metallographic approach

The aim of this paper is to contribute to the understanding of the organisation of the manufacture and circulation of iron bars and the possible bar standardisation of a given set of artefacts in order to throw more light on commercial patterns during Antiquity. A set of 48 iron based metal bars originating from the Roman shipwrecks at Les Saintes-Maries-de-la-Mer (France) has been studied using comprehensive metallographic observations, ranging from macroscopic to microscopic scales and slag inclusion (SI) analyses. A comparison of the results allows one to distinguish different metal qualities (inclusions, pores, welding, carbon content) that may be linked to morphological types, which shows the possible standardisation of this set of artefacts. Moreover, SI analyses allow distinguishing various origins for the Primary Pieces of Metal, thereby throwing light on a specific organisation of the iron bar production line during the late Roman period.     

On bad terms: Problems and solutions within zooarchaeological bone surface modification studies

The identification of butchery marks in the zooarchaeological record has consistently been debated. Much experimental work has been done to understand the causal agents behind some bone surface modifications, but recent controversies show that there is still no consensus. Terminology is not consistent between researchers, and there is ambiguity in how characteristics of marks are described and interpreted. There is also a lack of understanding of what causes individual variables within marks made by different agents, which is compounded by mark morphologies being described in terms that imply their causality. This paper examines these two problems in light of historic and current trends in the taphonomic literature, and recommends ways to describe marks that will facilitate more effective communication between researchers. It is proposed that greater standardisation within zooarchaeology is needed in seven key areas, and that this is the best avenue for moving into a new phase of taphonomic research.
