In discussing the reason for Augustine’s visit to Caesarea in 418, a clear distinction should be made between what we know for a fact and what we can deduce by inference. Furthermore, we should not regard incidents which were a consequence of the visit as constituting its pretext. The episode for which it is best remembered is Augustine’s encounter with the Donatist Bishop Emeritus, and the saint’s unsuccessful attempt to persuade him to return to Catholic unity. But the meeting between the two protagonists of Catholicism and Donatism seems to have been fortuitous. Again, Augustine was able, while at Caesarea, to prevail on the citizens to discontinue the Caterva, the organised local brawl, hallowed by tradition though by nothing else, which came to resemble a miniature civil war. But Augustine had not made a special journey to Caesarea to speak against the Caterva. His own explanation of the visit is that he went to Caesarea on the orders of Pope Zosimus to settle some ‘ecclesiastical necessity’ which had arisen there, and this assertion is echoed by his biographer, Possidius.
