ACQUAVIVA, DIOCESE OF. — In the Roman synod of 465 and in those following up to 502, two bishops, PAOLO and BENIGNO, appear respectively with the title of A.
In the 17th century, F. Ughelli wrote that some placed that episcopal see in Campania, others in Apulia, and still others in Roman Etruria. Ughelli subscribed to the opinion of the latter, while in more recent times T. Mommsen was unable to decide between Etruria and Apulia. L. Duchesne favors Etruria, though with some hesitation, while De Vit does not hesitate to adopt Ughelli’s opinion, as F. Lanzoni has recently done, whereas J. Fraikin still argued for Apulia.
A. in Etruria was a *mutatio* (station) on the Via Flaminia, not far from Civita Castellana, to the east of Soratte. Its ecclesiastical territory must have extended along the consular road in the direction of the diocese of Rome. It is probable that the ancient Christian cemeteries of Rignano and Morlupo, in the region of the Capenates, belonged to the diocese of A., which disappeared after 502. Its territory was probably annexed to the diocese of Porto.
