ABSTRACT

With the establishment of the court of Valentinian I in Trier (October 367), the new emperor resumed direct control over the affairs of the Gallic prefecture.1 Although an acknowledged imperial residence since the middle of the third century, Valentinian’s immediate predecessors preferred not to reside at Trier when in Gaul. Constantius II stayed in Arles (353/4), and Julian in Reims and Paris. Valentinian himself, when moving to the west, spent some months in Italy, and then proceeded to Gaul, settling first in Paris, then in Reims, Amiens, and finally in Trier.
