Arsacid dynasty of Armenia
A number of Zoroastrian fire-altars had been discovered in Christian sanctuaries in Armenia. In various parts of Armenia, Zoroastrianism lingered on for several centuries even after the official adoption of Christianity. The Arsacid dynasty of Armenia, under which Armenia eventually would become a Christian nation, were pious Zoroastrians who invoked Mithra as the lord of covenants, as is proper. An episode which illustrates the Armenian Arsacids and their observance of the cult is the famous journey of Tiridates I to Rome in A.D. 65-66. The same aforementioned Tiridates I, brother of Vologases I of Parthia and founder of the Arsacid dynasty of Armenia, was a Zoroastrian magus or priest.
