Dystis

Dystis was a city and bishopric in Roman Libya, which remains a Latin Catholic titular see.
Its modern location has been postulated in northern Tunisia or somewhere in southern modern Libya.

History

Dystis was important enough in the Roman province of Libya Superior -Libya Pentapolitana; originally part of Cyrenaica - to become one of the suffragan sees in this province, which depend directly on the Patriarchate of Alexandria without a proper Metropolitan, but faded like most bishoprics in Roman Africa.
Its only recorded Suffragan Bishops were:

Samuel, participant in the council of Ephesus in 431
Petrus, attending the Synod of Constantinople |synod of Constantinople in 458 against simony.

Titular see

In 1933 the diocese was nominally restored as Latin Titular bishopric of Dystis / Dystien / Disti.
It is vacant, having had only these incumbents, all of the fitting Episcopal rank, with an archiepiscopal exception :

André-Joseph-Prosper Dupont, White Fathers as last Apostolic Vicar of Bobo-Dioulasso , next promoted first Bishop of Roman [Catholic Diocese of Bobo-Dioulasso] ; died 1999
Antonio Oña de Echave as Auxiliary Bishop of Roman [Catholic Diocese of Lugo|Lugo] , next succeeded as Bishop of Lugo ; died 1987
Titular Archbishop Emilio de Brigard Ortiz as Auxiliary Bishop of Roman Catholic [Archdiocese of Bogotá|Archdiocese of Bogotá] , which he was previously as Titular Bishop of Coracesium.
