As we draw nearer to German ground, the ecclesiastical boundaries are found to have been somewhat more strongly affected by political changes. ♦Besançon.♦ The ecclesiastical province of _Besançon_ answers to _Maxima Sequanorum_; but it is not quite of the same extent; the boundary of the German and Burgundian kingdoms passed through the Roman province: its eastern part is therefore found in a German diocese. ♦Rheims.♦ The province of _Rheims_ answers nearly, but not quite, to _Belgica Secunda_: for the ecclesiastical province took in some territory to the east of the Scheld. Here again the boundary of the Eastern and Western kingdoms passed through the province. The metropolitan city lay within the region which became the kingdom of France, and it became the ecclesiastical head of the kingdom. Yet one of its suffragan sees, that of _Cambray_, was a city of the Empire. ♦Trier, 785.♦ The province of _Trier_ took in no part of the Western kingdom; but, besides the old province of _Belgica Prima_, it stretched away over the German lands even beyond the Rhine. ♦Köln, 785.♦ When the old Gaulish bishoprick of _Colonia Agrippina_ became metropolitan under Charles the Great, its province took in nearly all the old Gaulish province of _Germania Secunda_; but it too came to stretch beyond the Rhine and beyond the Weser. These two metropolitan sees, Trier and Köln, were old Gaulish bishopricks of the frontier land. ♦Mainz, 747.♦ The see of _Mainz_ has no certain historical being before Boniface in the eighth century. It too was founded on what was geographically Gaulish soil; but the greater part of its vast extent was strictly German. Three only of its suffragans, _Worms_, _Speyer_, and _Argentoratum_ or _Strassburg_, were even geographically Gaulish. No province has had more fluctuating boundaries: the elevation of Köln to metropolitan rank cut it short to the west, while it grew indefinitely to the north, south, and east, as its boundaries were enlarged by conversion and conquest. ♦Prag, 1344.♦ To the east it was cut short in the fourteenth century when the kingdom of Bohemia and its dependencies were formed into the ecclesiastical province of _Prag_. ♦Bamberg, 1007.♦ The famous bishoprick of _Bamberg_, locally in the province of Mainz, was from the beginning immediately dependent on the see of Rome. ♦The three ecclesiastical Electors and Arch-chancellors.♦
