Adrian abbot of the monastery of Neridan, near Naples. Pope Vitalian selected him to fill the vacant see of Canterbury, but he refused, and induced the pope to select Theodore instead, promising that he would accompany him. Accordingly Theodore was consecrated in 668; and upon their arrival in England, after a very long journey, Adrian was made abbot of the monastery of St. Augustine at Canterbury. By their united efforts the Church in England was brought into strict conformity with that of Rome. He died January 9th, 709. — Bede, Hist. Eccl. 4, 1; Hook, Eccl. Biog. 1, 66.
