Archelaus

After Herod died, an angel of the Lord appeared in a dream to Joseph in Egypt and said, “Get up, take the child and his mother and go to the land of Israel, for those who were trying to take the child’s life are dead.” ¶ So he got up, took the child and his mother and went to the land of Israel. But when he heard that Archelaus was reigning in Judea in place of his father Herod, he was afraid to go there […].

The date of the Disputation itself admits of tolerably exact settlement. Epiphanius, indeed, says that Manes fled into Mesopotamia in the ninth year of the reign of Vaerianus and Gallienus, and that the discussion with Archelaus took place about the same time. This would carry the date back to about 262 A.D.
