Gratiana, Africa

Gratiana was an ancient city and bishopric in Roman Africa, which remains a latin catholic titular see.

Today Gratiana survives as a titular bishopric and the current archbishop, personal title, is Francisco Escalante Molina, apostolic nuncio to the Republic of the Congo and Gabon.

History
Gratiana, in modern Tunisia, was among the many towns of sufficient importance in the Roman province of Byzacena to become a suffragan of Carthage, but would completely fade, plausibly at the 7th century advent of Islam.

During the Roman Empire the bishopric was centered on a town (now lost to history ) in  the Roman province of Byzacena. Three of its bishops are historically documented:
 * The Donatist bishop who attended the 411 Council of Carthage. On that occasion the seat had no Catholic bishops.
 * Bishop Boniface took part in the synod assembled in Carthage in 484 by the Vandal king Huneric, after which Boniface was exiled like most Catholic bishops.
 * Bishop Gennarus participated in the anti-monotheistic Council of Carthage (641).

Titular see
The diocese was nominally restored in 1933 as a titular bishopric of Gratiana (Latin) / Graziana (Curiate Italian) / Gratianen(sis) (Latin adjective)

It has had the following incumbents, albeit so far none of the fitting Episcopal (lowest) rank but all archiepiscopal:
 * Titular Archbishop Felice Pirozzi (Italian) (1961.10.28 – death 1975.07.25) as papal diplomat : Apostolic Delegate to Madagascar (1960.09.23 – 1967.01.09), Apostolic Nuncio (ambassador) to Venezuela (1967.01.09 – 1970.10.17) and as President of Pontifical Ecclesiastical Academy (1970.10.17 – 1975.07.25)
