GRATIAN, the son of Valentinian I. by his first wife, was declared Augustus by his father at the city of Amiens in 365, and succeeded him in 367; a prince equally extolled for his wit, eloquence, modesty, chastity, and zeal against heretics. He associated Theodosius with him in the empire, and advanced the poet Ausonius to the consulate. He made a great slaughter of the Germans at Strasburg*, and hence was furnished Alemannicus. He was the first emperor who refused the title of Pontifex Maximus, upon the score of its being a Pagan dignity. He was assassinated by Andragathius in 375, in the 24th year of his age.
