Bishop Petrus of Hydruntum (968) was raised to the dignity of Metropolitan by Polyeuctus, Patriarch of Constantinople (956-70), with the obligation to establish the Byzantine Rite throughout the new ecclesiastical province, and the authority to consecrate bishops in the churches of Acerenza, Tursi, Gravina, Matera, and Tricarico, all previously dependent on the Church of Rome.Mann, p. 293. Kehr, p. 408. The Latin Church was introduced again after the Norman conquest, but the Byzantine Rite remained in use in several towns of the archdiocese and of its suffragans, until the sixteenth century.
