Ambrose, Bishop, to the most blessed prince and most gracious Emperor Valentianus, the august.
1. Since the illustrious Symmachus, Prefect of the city, has sent petition to your Grace that the altar, which was taken away from the Senate House of the city of Rome, should be restored to its place; and you, O Emperor, although still young in years and experience, yet a veteran in the power of faith, did not approve the prayer of the heathen, I presented a request the moment I heard of it, in which, though I stated such things as it seemed necessary to suggest, I requested that a copy of the Memorial might be given to me.
