One of Zenobia's inscriptions recorded her as "Septimia Bat-Zabbai, daughter of Antiochus". Antiochus' identity is not definitively known: his ancestry is not recorded in Palmyrene inscriptions, and the name was not common in Palmyra. This, combined with the meaning of Zenobia's Palmyrene name (daughter of Zabbai), led scholars such as Harald Ingholt to speculate that Antiochus might have been a distant ancestor: the Seleucid king Antiochus IV Epiphanes or Antiochus VII Sidetes, whose wife was the Ptolemaic Cleopatra Thea. In the historian Richard Stoneman's view, Zenobia would not have created an obscure ancestry to connect herself with the ancient Macedonian rulers: if a fabricated ancestry were needed, a more direct connection would have been invented. According to Stoneman, Zenobia "had reason to believe Seleucid ancestry to be true". The historian Patricia Southern, noting that Antiochus was mentioned without a royal title or a hint of great lineage, believes that he was a direct ancestor or a relative rather than a Seleucid king who lived three centuries before Zenobia.
