Who Emperor Gratian was

Valentinian's son, emperor at sixteen — the pupil for whom Ambrose wrote On the Faith, the colleague who raised Theodosius after Adrianople, and the first emperor to refuse the robe of pontifex maximus, strip the state subsidies from the old cults, and carry the Altar of Victory out of the Senate house. He recalled the bishops Valens had exiled and returned the churches to the Nicene communion; Magnus Maximus's revolt caught him at Lyon, where he was murdered at a parley. Typed external per the emperor rule.
