[1][2] S. Paternianus is credited with being the first Bishop of Fano,[3] and is supposed [weasel words] to have been appointed by Pope Sylvester I (314–335).

[6] Among the later bishops were Riccardo (1214), persecuted by the magistrate Alberghetti; and the Dominican Pietro Bertano (1537), an orator and advocate at the Council of Trent.

[9] The cathedral Chapter was composed of two dignities (the Provost and the Archdeacon) and twelve Canons, one of whom is called the Poenitentiarius and another the Theologus, as mandated by the Council of Trent.

[16] In a decree of the Second Vatican Council, it was recommended that dioceses be reorganized to take into account modern developments.

[17] A project begun on orders from Pope John XXIII, and continued under his successors, was intended to reduce the number of dioceses in Italy and to rationalize their borders in terms of modern population changes and shortages of clergy.

There was to be only one episcopal curia, one seminary, one ecclesiastical tribunal; and all the clergy were to be incardinated in the diocese of Fano-Fossombrone-Caglia-Pergola.
