The Neo-Elamite period (ca. 1000-520 BCE), spanning the centuries from the end of the Middle Elamite Shutrukid dynasty to the rise of the Persian Empire, long remained one of the most poorly known intervals in Elam’s history. It was only in the early 1980s with the delineation of a Neo-Elamite ceramic sequence at Susa by French archaeologist Pierre de Miroschedji that archaeological material of this period could be more reliably identified and studied. In subsequent decades, scholars have gradually proceeded to unveil a rich picture of first millennium Elam and its material culture. One element of this picture that has remained conspicuously absent, however, is the reconstruction of mortuary practices. The irony of this situation becomes palpable when one realises that a large proportion of Elamite archaeological material admired today through sterile glass museum cases had once been buried with the Elamite dead; deliberately selected, with all its embodied meaning, for the funerary ritual. This thesis presents the first in-depth study of mortuary practices for any period of Elamite history, exploiting as fully as possible the preliminary reports and recently published archives of Roland de Mecquenem who recovered many thousands of burials during his tenure as head of excavations at Susa from 1912 to 1939. While scholars have tended to disregard these early discoveries due to the poor recovery and recording methods employed, generally conceiving only the art historical significance of the objects, I hope that my own work amply demonstrates that it is still possible, and indeed necessary, to exploit these resources in order to reconstruct Elamite mortuary ritual and belief. The data from Susa, studied in conjunction with the small sample of published burials from other Neo-Elamite sites and fleshed out by additional evidence from texts and other aspects of the material record, starts to bring this intriguing facet of Elamite society back to life.
