"the skilful mediation of the merchant Opramoas"

Opramoas was a wealthy individual from Rhodiopolis in Asia Minor (modern Turkey). He was a proponent of "euergetism," a Pagan Hellenistic and Roman form of philanthropy. Inscriptions from his mausoleum state that he donated money for the education of children, for the burial of the poor and for the dowries of girls from poor families. Clearly he was a man of substantial wealth, and it is likely that he was involved in trade between Asia and the Roman Empire, so he would have been well-placed to play the role ascribed to him here, although there is no evidence that he actually did so.
