Abstract

Geochemical and isotopic analysis of the bitumen lining of torpedo jar sherds from the Sasanian to early Islamic period fort of Fulayj in Oman confirms the presence of two distinct compositional categories that can be matched to contemporary sources in different areas of southwest Iran. It appears that the bitumen used to line jars was extracted from different geographic areas, hinting at the existence of multiple production locations for this vessel class. On the function of the jars, organic residue analysis provides a positive identification of biomarkers associated with the storage and transport of red wine. These results provide the first published confirmation of the long suspected association between torpedo jars and wine transportation from the core urbanised zone of the Sasanian and early Islamic imperial heartlands towards the Persian Gulf and Indian Ocean maritime sphere. The results have added significance as the samples are derived from relatively accurately dated archaeological contexts spanning the period before and after the Islamic conquest.
