 In the ninth century the Saracens laid waste Apulia, destroyed the city of Canosa (Canusium) and captured Bari.In 841, however, the Byzantine army reconquered Bari, and in 844 Bishop Angelarius, Bishop of Canosa, brought to Bari the relics of Rufinus, Memorus, and Sabinus of Canosa, which he had rescued from the ruins of Canosa.Pope Sergius II conferred on Angelarius the title of Bishop of the two dioceses of Bari and Canosa, a title which the archbishops of Bari retained up to 1986.
