Petrological Examination of Coarse-ware Stirrup-jars from Mycenae

Abstract

Elemental analysis of coarse-ware stirrup-jars from Thebes provided the first objective evidence for the movement of coarse wares in the Late Bronze Age Aegean. While the evidence of the optical emission spectrometry analysis indicates that stirrup-jars occur in several fabrics, the assignation of these fabrics to specific sources has been the subject of some debate, summarized and discussed in the light of fresh evidence by Catling and Jones but continued by McArthur.It was to cast more light on the general questions that a large sample of stirrup-jars from Mycenae was analysed by petrological analysis. This method of analysis involves the identification of the rocks and minerals within the clay and relates them to geological sources most compatible with the archaeological evidence. Recent discussions of the method include Courtois, Peacock, and de Paepe.With considerable help and collaboration from Dr. E. French and Lord William Taylour, and permission from the Greek Department of Antiquities, 37 samples were taken from stirrup jars from the House of the Wine Merchants (= HWM; dated LH IIIA/B), 25 from the House of the Oil Merchants (= HOM; dated to the end of LH IIIB1), and ten samples from stoppers found in the stirrup jars in the House of the Oil Merchants. The aim was to define the fabrics petrologically in order to relate these to the typology proposed by Haskell (this volume), and to suggest possible origins for them based on geological evidence.
