 Apart from some bishops who may have been of the church in Caesarea and whose names are engraved in inscriptions that have been unearthed, the first bishop whose name is preserved in extant written documents is Fortunatus, who took part in the Council of Arles of 314, which condemned Donatism as heresy.A letter of Symmachus mentions a bishop named Clemens in about 371/372 or 380.The town became a Donatist centre and at the joint Conference of Carthage in 411, was represented both by the Donatist Emeritus and by the Catholic Deuterius.
