Three bishops are known: Tertullian, present at the conference of Carthage in 311; Saturus, exiled in 484 by Huneric with many other bishops; Theodore, who in 641 signed the letter from the Council of Byzacium to Constantine, son of Heraclius, against Monothelitism.
It remains a Roman Catholic titular see.
