Thagaste (diocese)
The Diocese of Thagaste is an ancient and famous Titular See of the Roman Catholic Church. The ancient Roman town of Tagaste, corresponding to the city of Souk Ahras in Algeria, was the seat of an ancient episcopal diocese during the Roman and Vandal empires in what was the Roman province of Numidia. Tagaste is famous for being the birthplace of Augustine, who was a bishop in nearby Hippo (now Annaba), and his mother, Monica. Near Tagaste, Saint Melanie the young founded two monasteries in one of the vast possessions of her property in Roman Africa, where she  lived a few years before going to Jerusalem where she died in 439. The first known bishop of Tagaste is Fermo, who suffered martyrdom in the late 3rd century and is remembered by the Vetus Martyrologium Romanum on 31 July: "Tagaste, in Africa, sancti Firmi Episcopi, confessionis gloria conspicui". St. Augustine mentions it in the work The lie. The next known bishop is Alypius, a disciple and friend of Augustine, also remembered by "Vetus Martyrologium Romanum" on August 15.In Alipio Augustin dedicates three chapters of the book VI of his Confessions. The third known bishop of Tagaste is Gennaro, who  participated in the synod gathered in Carthage by the Huneric the Vandal in 484, after which he was exiled. Today, Tagaste survives as a titular bishop's seat; the current archbishop, personal title, holder is Ivo Scapolo, apostolic nuncio to Portugal.
