Under this emperor, Theophilus (829), Nicolas and Theodore again suffered persecution. Theodore, and the abbot Theophanes, kinsman of Nicolas, were mutilated by certain verses being cut upon their brows. During the persecution, S. Nicolas remained concealed; on the accession of the indifferent emperor, Michael III., (842), he emerged from his hiding place, and was elected archimandite of the Studium, the abbot Theodore being dead. After exercising the government for three years, he resigned it to Sophronius, and retired to Firmopolis, that he might pass the remainder of his days in peace; but it was not so to be; after four years he was recalled to the abbacy of the Studium, on the death of Sophronius, and was at once involved in conflict. For the patriarch Ignatius, having rebuked the Cæsar Bardas for incest, and then excommunicated him, the emperor Michael III., his nephew, was persuaded to exile Ignatius, and to intrude Photius into the Patriarchal see. The abbot Nicolas refused to communicate with the intruder, and was consequently driven from his monastery, and a monk, Achillas, was appointed in his room. Nicolas was pursued from one retreat to another by the hostility of the intruded patriarch, and after many wanderings, rested in the Crimea. Upon the death of Bardas and Michael, Bardas having been murdered by his nephew Michael, and Michael by his successor, Basil I., (867), the patriarch Ignatius was recalled, and the patriarch persuaded Nicolas to return to his government of the Studium, where he died the following year.
