"Each prefecture was divided into several dioceses under vicarii (vicars)."
"On the other hand, the ancient office of vicarii foranei, decani rurales, or archipresbyteri still exists in the Church (see ARCHPRIEST; DEAN)."
"A complete but uncritical list of the vicarii in spiritualibus in urbe generales, was published by Ponzetti (Rome, 1797); it was added to and improved by Moroni (Dizionario, XCIX)."
