The name of Viterbo occurs for the first time in the 8th century, under
Pope Zachary, when it was a village tributary to
Toscanella, in
Lombard Tuscany (Tuscia Langobardorum) on the
Via Cassia.
Charlemagne gave the pope all this Tuscan territory in feudal tenure, the imperial authority over it being still represented by a
sculdascio (feudal sheriff) and later by a count.
Toscanella Bishop Maurus is the first known bishop (649) of Toscanella. Among the successors of Maurus was Virbonus, to whom
Pope Leo IV addressed a bull on 23 February 852, determining the boundaries of the diocese. In 876, Bishop Joannes was one of the legates of
Pope John VIII at the council of Pontigny, and carried the imperial insignia to
Charles the Bald. During the tenth century Toscanella was for some time under the
Bishop of Centumcellae. The succession of its bishops recommences with Joannes (1027); another Joannes distinguished himself in the reform of Benedict (1049) and brought back the clergy of Tuscania to the common life. Gilbert (1059) and Giselbert (1080) were also promoters of reform. Bishop Richard (1086–1093), however, adhered to the party of Frederick Barbarossa's
antipope Clement III, who, in 1193, united Toscanella with Centumcellae and the
see of Blera.
Viterbo In 1192
Pope Celestine III made it the
diocese of Viterbo, on territory split off from the
diocese of Tuscanella, but jointly held (
aeque personaliter) with that see until 1913. The episcopal seat was transferred from Toscanella to Viterbo. Viterbo was notorious as a center of heresy. During the episcopate of Bishop Raynerius (c.1200), the
Paterini, who practiced a form of gnostic manicheanism, first appear in Viterbo. Pope Innocent III came to Viterbo personally in June 1207, and engaged in the search for Paterini and their sympathizers, most of whom had fled. They were active, however, throughout the 13th century, and were still found there in 1304. In the fourteenth century the clergy of Toscanella repeatedly refused to recognize the bishop elected by the chapter of Viterbo, so that
Pope Clement V (1312) reserved to the
Holy See the right of appointment. The episcopal palace was completed in 1267, under the auspices of Raynerius Gatti, Captain of the People of Viterbo for the third time. The
papal election of 1268–1271, the longest in papal history, took place in the episcopal palace in Viterbo. The experience led directly to the forming of the first rules for holding a papal conclave. The territory of the diocese was stricken by a major earthquake on 28 May 1320. In 1353,
Cardinal Albornoz, who was appointed
Legatus a latere and Vicar in spiritualities and temporalities for all the lands in Italy subject to the dominion of the Church, came to effect the reconquest of the
Papal States. He invested Viterbo with a siege, beginning in May 1354. On 23 June, Viterbo submitted, and built a fortress (Rocca) for the governor of the Patrimony. In 1367, during the sojourn of
Pope Urban V at Viterbo, a quarrel between the populace and the retinue of one of the cardinals developed into a general uprising, which Cardinal
Marcus of Viterbo, who had arrived at the papal court from Genoa on 8 September, quickly put down. The incident is reported in great detail by Pope Urban V himself, in the bull "Pii Patris" of 1 December 1367, in which he lifted the censures imposed upon Viterbo because of the incident. On 31 August 1369, the diocese lost territory when
Pope Urban V established the
Diocese of Montefiascone. In 1375
Francesco di Vico took possession of the city, which joined in the general revolt against papal rule, but quickly submitted. When the
Western Schism arose, Vico's tyranny recommenced; he took the side of
Pope Clement VII and sustained a siege by Cardinal Orsini. The people rose and killed him (8 May 1387), and Viterbo returned to the obedience of
Pope Urban VI. But in 1391
Gian Sciarra di Vico reentered the city and took possession of its government. In 1391 Cardinal Pileo, the
papal legate of
Clement VII, would have given the city over to
Pope Boniface IX, but his plan failed, and he fled, so Vico came to an understanding with Boniface. On 5 December 1435, the city of Corneto was separated from the Diocese of Viterbo and erected as the
Diocese of Corneto by
Pope Eugenius IV, and joined with the then recently erected
Diocese of Montefiascone. After a century of trouble, peace was not re-established until 1503, when the government of Viterbo was subsequently assigned to a
cardinal legate, rather than to the governor of the Patrimony. One of its cardinal legates was
Reginald Pole, around whom there grew up at Viterbo a coterie of friends,
Vittoria Colonna among them (from 1541 to 1547), who aroused suspicions of heterodoxy. After 1628 Viterbo was the residence again of a simple governor. On 2 May 1936 the diocese of Viterbo e Toscanella gained territory from the suppressed Territorial Abbacy of San Martino al Monte Cimino.
Restructuring The
Second Vatican Council (1962–1965), in order to ensure that all Catholics received proper spiritual attention, decreed the reorganization of the diocesan structure of Italy and the consolidation of small and struggling dioceses. It also recommended the abolition of anomalous units such as exempt territorial prelatures. These considerations applied to Viterbo and the other dioceses governed by its bishop. On 18 February 1984, the Vatican and the Italian State signed a new and revised concordat. Based on the revisions, a set of
Normae was issued on 15 November 1984, which was accompanied in the next year, on 3 June 1985, by enabling legislation. According to the agreement, the practice of having one bishop govern two separate dioceses at the same time,
aeque personaliter, was abolished. Instead, the Vatican continued consultations which had begun under
Pope John XXIII for the merging of small dioceses, especially those with personnel and financial problems, into one combined diocese. By 1986, papal policy in the selection of bishops had concentrated in the person of Bishop Luigi Boccadoro the
Diocese of Viterbo e Tuscania, the diocese of
Acquapendente (since 1951), the diocese of Montefiascone (since 1951), and the Administratorship of the diocese of Bagnoregio (since 1971); he was also the Abbot Commendatory of Monte Cimino. On 27 March 1986, by the bull "Qui Non Sine",
Pope John Paul II moved to consolidate these several small dioceses by suppressing them and uniting their territories into the diocese of Viterbo e Tuscania, whose name was changed to the Diocese of Viterbo. There was to be only one cathedral, in Viterbo. The cathedrals in Acquapendente, Montefiascone and Bagnoregio were to become co-cathedrals, and the cathedral Chapters were each to be a
Capitulum Concathedralis. There was to be only one diocesan Tribunal, in Viterbo, and likewise one seminary (the regional papal seminary), one College of Consultors, and one Priests' Council. All the priests of all the dioceses were to be incardinated in the diocese of Viterbo.
Diocesan synods The
Fourth Lateran Council (1216) decreed that provincial synods should be held annually in each ecclesiastical province, and that each diocese should hold annual diocesan synods. A diocesan synod was an irregularly held, but important, meeting of the bishop of a diocese and his clergy. Its purpose was (1) to proclaim generally the various decrees already issued by the bishop; (2) to discuss and ratify measures on which the bishop chose to consult with his clergy; (3) to publish statutes and decrees of the diocesan synod, of the provincial synod, and of the Holy See. Bishop Angelo Tignosi (1318–1343) held a diocesan synod at Corneto on 16 May 1320, and another three years later in Viterbo. Cardinal Tiberio Muti (1611–1636) presided over a diocesan synod, his second, in Viterbo on 18–19 January 1624; its acts were published. Cardinal Francesco Maria Brancaccio held a diocesan synod in Viterbo on 18 September 1639, and had the acts of the synod published. Brancaccio held another synod on 21 November 1649, and published the acts. A diocesan synod was held in the cathedral of Viterbo by Cardinal Urbano Sacchetti (1683–1701) on 24–25 May 1694; its acts were published. == Bishops ==
