d.672. Pope from 657. Born at Segni, he was enthroned as successor of Eugenius I, and announcing his accession to the emperor Constans II, thereby instituted friendly relations between Rome and Constantinople during the early part of his reign and also during the Monothelite* controversy. Unsuccessful in attempts to exert jurisdiction over Maurus, bishop of Ravenna, who refused to appear in Rome, he had good relations with England since he consecrated Theodore* as archbishop of Canterbury in 668. Relations between East and West were not helped when Vitalian's name was removed from the Diptychs (list of people for whom prayers were said) in the church of Constantinople.
