According to the "Notitia Dignitatum", the dioceses of Dacia and Illyricum did not have vicars, but were governed by the Praetorian Prefect of Illyricum directly. Before its suppression, the Diocese of Gaul also seems to have been directly administered by the Praetorian Prefect of Gaul. In fact, according to Jones, the diocese in which each Praetorian Prefect was based was generally under their direct control, except for the Diocese of Thrace, which was administered by a "vicarius Thraciarum" even though the Praetorian Prefect of the East had his seat in the diocese. The title of vicar was used in all provinces except for the Diocese of the East, which was governed by a "comes Orientis" and Egypt, which continued to be governed by a Prefect.
