He saw its efficiency for securing discipline among the clergy. Like other strong rulers, he regarded anarchy with aversion, and was therefore anxious to introduce the rule into England. He intrusted the work to his friend Æthelwold, whom he made Bishop of Winchester, and to Oswald, whom he raised to the See of Worcester. In Wessex and Mercia he carried out his reform with vigour, even with violence: but, as in his secular government, he kept himself under the restraints of prudence. Thus, when Oswald was appointed Archbishop of York, he made no efforts to restrain the marriage of the clergy, and in Dunstan’s own See he yielded to the prejudices of the people, and allowed the abbeys to continue in the hands of secular clerks. The title of Eadgar the Peaceful, and a reign of seventeen years unbroken by any great foreign war, attest the success of Dunstan’s policy. [Sidenote: Eadward the Martyr 975-979.] [Sidenote: Fall of Dunstan.] But with Eadgar’s death, and the accession of his son Eadward, this prosperous state of things ended. For a time Dunstan held his own, but not without strong opposition. Again and again he had to plead his cause before the Witan. And at one synod, at Calne, it was intended to bring the matter to a crisis. Beornhelm, a Bishop of the Scottish Church, was brought forward as a champion by his enemies. His eloquence was carrying the assembly with him, and Dunstan could only appeal to heaven for assistance. Nor was that assistance denied; by accident or design, the floor of the upper chamber where the meeting was held gave way in that part where Beornhelm and his friends were seated, and they were hurried to swift destruction, while Dunstan’s triumphant party remained uninjured on the floor above. But even miraculous interferences did not suppress the enemies of the Prelate. A conspiracy, in which Ælfthryth [Elfrida], the mother of Ethelred, seems to have been chiefly engaged, was formed; and Eadward, returning from the chase, was killed at her castle at Corfe.
