Pope Gregory II
As the schism lost its vigour, the Lombards started to renounce Arianism and join western orthodoxy. The bishop of Old-Aquileia formally ended the schism at the Synod of Aquileia in 698. After Old-Aquileia reconciled with Rome, Pope Gregory II granted the pallium to Patriarch Serenus (715–730) of Aquileia in 723. The division of the Patriarchate of Aquileia into the rival Patriarchies of Aquileia and Grado contributed to the evolution of the Patriarch of Grado into the present Patriarch of Venice.
