"There is simply nothing Indian, much less South Indian, in the setting and ambiance of the Acts of Thomas. All internal evidence suggests Syria, Iraq and Persia – or Parthia as it was called in the first century CE – as the place where the drama of the Acts was played out to its preordained end, or to a kingdom on the edge of the Roman Empire – like Edessa itself – as there are strong Greco-Roman influences in the text, India as a specific place and Gundaphorus and Misdaeus-Mazdai as Indian kings appear to be literary devices used by Bardesanes to give credibility to the unconventional religious theme of the book."
