"These wool textile fragments feature dark brown and white stripes. They were excavated at Shahr-i Qumis in northern Iran, which has been identified as the ancient city of Hecatompylos, established by the Parthians as their capital by about 200 B.C. However, these fragments come from Room 23 at Site VI, which was seemingly converted into a burial chamber during the 6th century A.D., a date indicated by a coin of the Sasanian king Hormizd IV (reigned A.D. 579-590). The human remains discovered there consist of disarticulated bones, which is in keeping with Zoroastrian burial practice. Yet the bones appear to have been wrapped in leather and wool, which would be unusual for Zoroastrians, as is the inclusion of a coin with the body. Thus it is possible that in the 6th century Zoroastrian burial practices were still under development or that there were regional variations that are not recorded in surviving texts."
