in the papal archives. 245 Since only two metropolitans were to be appointed, it seems clear that Gregory had found nothing of later date than third-century in the archives, otherwise he would have had to authorize the appointment of four (or five) metropolitans. It has been suggested that, after A.D. 297, Diocletian (in theory along with Maximian) established a third province by taking some city territories from each of the two existing provinces and forming the new province in between them. This new province, it is claimed, was named Caesariensis, or Britannia Caesariensis (or Maxima Caesariensis), taking that name from its capital, a city named Caesarea. The new province was then later subdivided into Flavia Caesariensis and Maxima Caesariensis. It has to be said at once that there is no evidence whatsoever that any British city was ever named Caesarea. It has also to be said that when provinces were subdivided, whether during the Principate or under Diocletian or later, it was not normal procedure to take city territories from the adjacent parts of two provinces, thus creating a new province in between. Most subdivisions of provinces are simply that-the province is divided, whether it was Moesia in the early A.D. 80s, or Pannonia shortly after A.D. 100, or Dacia after 106, or Syria in 194, or Britain in 197. Under Diocletian, Mauretania Sitifensis is simply carved out of Mauretania Caesariensis, Sequania out of the southern half of Germania Superior, Valeria out of the northern part of Pannonia Inferior, and Scythia out of the northern part of Moesia Inferior. In general, a new province is merely a part of a previous province. The only exception seems to be the special case of the new province of Dacia south of the Danube, which included city territories taken from Moesia Superior, Thrace, and Moesia Inferior. But then, Aurelian was virtually pretending that Dacia north of the Danube had not been permanently given up at all. Occasionally, individual cities might be transferred to a different province, apparently simply for administrative convenience, by equalizing the size of provinces. Thus the Lingones were transferred from Sequania to Lugdunensis Prima, and the Tungri from Gallia Belgica to Germania Secunda. It is difficult to see any point in creating a province which took its city territories from two other provinces: it seems a recipe for conflict. It is also difficult to see how, if this new province were later divided, both halves could be named Caesariensis, as if both were claiming that its capital was still Caesarea. It is more probable that Maxima Caesariensis and Flavia Caesariensis were created at the same timebut with a difference. As Richard Goodchild suggested to me, in a letter written shortly before he died,
