"This king (Misdaeus) is better known by his Persian name, Mazdai, which is found in the Syriac version of the Acts (Misdaeus is Greek). It specifically denotes a Zoroastrian ruler. He has no known historical counterpart and the Acts gives no vital information about him except to say that he rules in “a desert country”."
