His Return to Alexandria

13. It is practically certain that Dionysius returned to Alexandria as soon as Gallienus’s edict came into operation there. But almost immediately fresh disturbances were felt in the city, followed by one of those frequent outbreaks of pestilence to which the East was always liable, and these hindered for a time his work of bringing the brethren together again. The disturbances are with good reason thought to have been those connected with the attempt of Macrianus to overturn the power of Gallienus in Egypt, though that country was so often the scene of tumults and civil wars for the next twelve years and more that it is almost impossible to identify any particular disturbances with certainty during this period.
