Catholic Encyclopedia (1913)/Gratianopolis

A titular see in Caesarea Mauretania, Africa. This city does not figure in a list of the bishoprics of the province preserved in a document of the sixth and seventh centuries, unless it be disguised under the native name (see "Byzantinische Zeitschrift", 1892, II, 26, 31). Its history, location, and present condition are unknown. Three of its bishops are known: Publicius (Catholic), Deuterius (Donatist), both at the Conference of Carthage in 411; and Thalassius, present at the Conference of 480.
