          breaking off communion with Rome and Constantinople which
        they considered to be in a heretic position. Later the bishops in
        Aquileia laid claim to the title of patriarchi, based on the tradition
        that St. Mark had preached in Aquileia. When the Grado patriarch made
        peace with Rome and Constantinople in 607 Aquileia elected a second,
        schismatic, patriarch, Abbot John, whose jurisdiction covered the
        dioceses in Lombard territory while the patriarch of Aquileia in Grado
        had the dioceses in Byzantine territory (coast area and Istria) under
        his jurisdiction. 
            John’s successor, Fortunato, transferred the patriarchal seat to the
        Castrum in Cormons between 608 and 628. The patriarch of Aquileia in
        Cormons ended the schism in 698, returning to Roman orthodoxy. In 737
        Patriarch Callisto moved his seat from Cormons to Cividale. He ordered
        the
        building of the patriarchal palace (more or less on the site of the

          present Palazzo dei Provveditori Veneti),
        the
        church of St John the Baptist (near the cathedral’s parvis) and the
        baptistery, whose famous tegurium still exists. 
            The eighth century was a period of political and cultural prosperity for
        the Lombard duchy of Friuli, Cividale became a meeting place for sovereign and aristocratic powers,
        ecclesiastic institutions and cultural hegemonies. In the same century
        the Altar of Duke Ratchis was made and the oratory of Santa Maria in
        Valle, better known as the “Lombard Temple”, was built. Furthermore,
        the monasteries in Sesto al Reghena, Salt and Santa Maria in Valle di
        Cividale were founded. 
            The peak of the town’s splendour coincided with the decline of Lombard
        rule. In 773 the Frankish king Charlemagne proclaimed himself king of
        the Lombards, in 776 Cividale was occupied by the Franks and its name
        changed to Civitas Austriae.  |
