Bocconia was an ancient city and former bishopric in Roman North Africa, which only remains a Latin Catholic titular see.

History

Bocconia was among the cities of sufficient importance to become a suffragan diocese in the Roman province of Numidia, in the papal sway, but faded so completely, probably at the 7th century advent of Islam, than even its precise location in present Algeria is unclear.

Its only historically documented bishops were :

• Donatus, partaking as Donatist schismatic bishop (without Catholic counterpart) at the Council of Carthage called in 411, precisely on that heresy.
• Vitalianus, Catholic bishop at the Council of Carthage called in 484 by king Huneric of the Vandal Kingdom, presumably exiled afterward.

Titular see

The diocese was nominally restored in 1933 as Latin titular bishopric of Bocconia (Latin = Curiate Italian) / Bocconien(sis) (Latin).

It has had the following incumbents, of the fitting Episcopal (lowest) rank :

• Thomas F. Quinlan (구 토마), Columban Missionaries (S.S.C.M.E.)
