(Calvensis et Theanensis).
The city of Calvi is the ancient Cales or Calenum in the Campagna, not far from Capua. Towards the end of the fifth century it was certainly a bishopric, since Valerius, Bishop of Calenum, was present at the Roman Council held by Pope Symmachus in 499. Destroyed in the ninth century by the Saracens, it was rebuilt by Atenulfo, Count of Capua, at which time, most probably, the see was re-established. It certainly had a bishop at the end of the eleventh century. Remarkable among the bishops were: Odoardo, who assisted at the Council of Lyons (1245) and vigorously opposed Frederick II, his sovereign, who, on his return, had him slain; Bernardo Spada (1543); the monk Gennaro Filomarino (1623). In 1818 Calvi was united with the See of Teano, a small city of the same province and a former fief of the Gaetani. Its first bishop was St. Paris, ordained by Sylvester I; according to tradition, St. Urbanus and St. Amasius were bishops of that city in the fourth century.
