CENTOCELLE. - This episcopal see, attested by documents from the fifth century, had an ephemeral existence.
L. Duchesne holds that the bishops of C. (Subaugusta) were merely those of Labicum, residing there at the fifteenth mile at that time, since the sources are simultaneously silent concerning the names of the bishops of the latter; on the other hand, F. Lanzoni and, more recently, T. Ashby and G. Lugli, for reasons that seem more persuasive, maintain that they were properly bishops of the place, of whom Crispiano in 465, Pietro in 487, Massimiano in 499, and Giocondo in 502 are certain. At about the fourth mile of the via Labicana, near the present-day airport of C., an imperial city had arisen in the fourth century, a sort of military quarter and fortified camp for the defence of the capital, called Subaugusta. The existence in the area of the imperial villa and mausoleum (Tor Pignattara) explains the origin of the episcopal see, which, however, was of very short duration, since it ceased at the beginning of the sixth century. Today only imposing ruins remain.
