The document comprises a list of the names of all the provinces of the empire, organised according to the 12 newly created regional groupings called dioceses. Although the 12 dioceses are presented in a single list, they are not ordered in a single geographical sequence but rather in two separate eastern and western groups, the eastern group preceding the western. The split is apparent from the discontinuity midway in the list between the dioceses of Pannoniae and Britanniae. The eastern half of the list circles the Mediterranean neatly anticlockwise from south to north or, in continental terms, from Africa, through Asia, to Europe. The arrangement of the western half is less tidy, though it is approximately anticlockwise from north to south, or from Europe to Africa. Theodor Mommsen had dated the provincial situation in the list to 297, but later research changed the estimate to 314–324 for the Eastern Half and 303–314 for the Western Half of the Roman empire. The most recent work by Timothy Barnes and Constantin Zuckerman concludes that the entire document belongs to a single moment, c. 314, the eastern and western parts corresponding to the respective spheres of responsibility of the emperors Licinius and Constantine during the period between Licinius’ defeat of Maximinus II in 313 and his own defeat in his first civil war with Constantine in 316-317.
