CENTOCELLE. – A fleeting existence was enjoyed by this episcopal see, which documents attest from the 5th century.
L. Duchesne is of the opinion that the bishops of C. (Subaugusta) were none other than those of Labicum at the 15th mile, residing there at that time, since the sources likewise remain silent regarding the names of the bishops of the latter; on the contrary, F. Lanzoni and more recently T. Ashby and G. Lugli, with reasons that seem more persuasive, hold that these were properly the bishops of the place, of whom certain ones are Crispian in 465, Peter in 487, Maximian in 499, and Jocundus in 502. At about the 4th mile of the Via Labicana, near the present-day Centocelle airport, an imperial city had formed in the 4th century, a sort of military quarter and entrenched camp for the defense of the capital, which was called Subaugusta. The presence 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, ceasing at the beginning of the 6th century. Today only imposing ruins remain.
