This paper presents the results of a project designed to investigate the techniques used to make late bronze age Aegean stirrup-jars and to determine whether the identified techniques were influenced by regional-cultural factors. The project was initiated by the need to address the question of whether 12th-cent. BC stirrup-jars from Tell es-Sa'idiyeh in the Jordan valley, apparently of local clay, were made by local potters or by immigrant Mycenaeans. The stirrup-jars studied comprised examples from Tell es-Sa'idiyeh, Gezer, the Greek mainland, Aegina, Rhodes, Cyprus, Caria, and Egypt. Xeroradiography was used to elucidate variations in construction techniques, and the findings were tested by practical experimentation. The observations indicate that there is a degree of linkage between the techniques of manufacture and cultural background. In order to make the discussion of production techniques more secure, neutron activation analyses were also carried out; these provided information on the place of manufacture as opposed to the find-spot, and have also thrown some interesting light on patterns of trade in the Mediterranean area towards the end of the Late Bronze Age.
