He initiated a number of reforms to prevent a return to the anarchy of previous generations and maintain the viability of the Empire.

Thus some argue for a date between 300 and 303, i.e. before the Diocletian persecution; others for a date between 303 and 314, after the persecution; but before the synod of Arles; still others for a date between the synod of Arles and ...

Arnobius of Sicca (died c. 330 A.D.) was a Christian apologist, during the reign of Diocletian (284 - 305).

According to Jerome, to overcome the doubts of the local bis ...
