Roman Catholic Diocese of Fissiana

The Diocese of Fissiana (Fissianensis) is suppressed Latin Church diocese and current titular see of the Catholic Church.

Location
The exact location for the seat of the diocese is unknown, though Fissiana, is tentatively located somewhere near Foussana in modern Tunisia. In antiquity it was within the Roman province of Byzacena, corresponding to the modern Sahel region of Tunisia.

History
Of this dioceses only two Donatist bishops are known. That the town was a stronghold of Donatism is not surprising, as it is located close to the heartland of that movement with many of the first Donatist congregations forming in the semi-arid region to the west and south west of Foussana.
 * Donato who participated in the Council of Cabarsussi, held in 393 by Maximianus, a dissident sect of the Donatists, and he signed the acts of that Council.
 * At the Council of Carthage (411), Bishop Turrasio represented the town, no Catholic competitor attended the conference.

Today Fissiana survives as titular bishopric and the current bishop is Alejandro Daniel Pardo, Auxiliary bishop of Buenos Aires.
