Erythrum

Erythrum was a city and bishopric in Roman Africa, which remains a Catholic titular see.

The city, identified with modern Uaili-Et-Trun, was important enough in the Roman province of (Creta and) Cyrenaica and later the split-off province Libya Superior or Libya Pentapolitana to become a suffragan of its capital's Metropolitan of Cyrene.

Cyrenaica was conquered by Muslim Arabs during the tenure of the second caliph, Omer Bin Khattab, in 643/44, After the breakdown of the Umayyad caliphate it was essentially annexed to Egypt, although still under the same name, first under the Fatimid caliphs and later under the Ayyubid and Mamluk sultanates. Ultimately, it was annexed by the Turkish Ottoman Empire in 1517 when it was part of the Tripolitania Vilayet.

Christian bishopric
The Diocese of Erythron was a center of Early Christianity in the Pentapolis of North Africa. It was an early Christian bishopric. The seat of the Diocese was the Roman town of Erython, tentatively identified with the village of Uaili-Et-Trun in today's Libya. We know of four bishops of the diocese from antiquity.
 * Orione (2nd century)
 * Sabbazio
 * Paolo
 * Theophilo (fl.451)
