Roman Catholic Diocese of Treviso

Through the intercession of Bishop Felix the city of Treviso was spared during the Lombard invasion (569) and became the seat of a duchy. Charlemagne made it a marquisate, extending from Belluno to Ceneda, and from the Adige to the Tagliamento. In 922 Treviso, which was under episcopal jurisdiction, was sacked by the Hungarians.

Treviso probably was Christianized from Aquileia. The first bishop of certain date was Jucundus, who in 421 took part in the consecration of the church of the Rialto in Venice. The bishops of Treviso who participated in the schism of the Three Chapters were: Felix (see above); Rusticus, present at the Council of Murano (588); and Felix II, who signed the petition to the Emperor Maurice.

In 905 Bishop Adelbert received from Berengar I of Italy the temporal jurisdiction of the city, which extended to Rozo (969–1001) and Rolando who adhered to the schism of Clement III. Bishop Tiso (1212–1245) suffered from the tyranny of Ezzelino, and Alberto Ricco, O. M. (1255), was imprisoned for preaching against him.

Other bishops were:

• Loto Gambacurta (1394), exiled by the Florentines from his archbishopric of Pisa;
• Giovanni Benedetti, O. P. (1418), who reformed many convents of his order and concubinary priests;
• Ludovico Barbo (1437), Abbot of S. Giustina of Padua, and reformer of the Benedictine order;
• Ermolao Barbaro (1443);
• Cardinal Pietro Riario, O. M. (1471);
• Fra Giovanni Dacri (1478), formerly minister general of the Franciscans, who restored the cathedral and reorganized the revenues of the bishopric, leaving many pious foundations;
• Nicolò Franco (1486), papal nuncio in various countries;
• Francesco Cornaro (1577), who founded a seminary, introduced the reforms of the Council of Trent, resigned his see, and was created cardinal;
• Gian Antonio Lupo (1646), who conflicted with his canons;
• Giambattista Saniedo (1684);
• Fortunato Morosini (1710);
• Bernardino Marini (1788–1817), a canon of the Lateran, present at the Council of Paris, 1811, who united the abbey nullius of Novisa with the See of Treviso
• Giuseppe Giapelli, appointed by the Austrian Government, but not recognized by the Holy See, so that the diocese remained in turmoil until the death of the candidate.

In 1818 Treviso passed from the metropolitan see of Aquileia (Udine) to the archdiocese of Venice. Bishop Giuseppe Grasser (1822) healed the conflicts caused by the interregnum. Bishop Giovanni Antonio Farina (1850) conferred sacred orders on Giuseppe Sarto, later Pope Pius X.

United with Treviso is the ancient Diocese of Asolo, the bishops of which are unknown from 587 (Agnellus) until 1049 (Ugo); and the diocese of Heraclea (diocese of Città Nova), a city founded in the times of the Byzantine emperor Heraclius, as a refuge for the inhabitants of Opitergium (Oderzo), who with their bishop (Magnus) had been exiled by the Lombards. Twenty-six bishops are known, from 814 until the union of the see with Treviso, 1440.[3]
