ADALBERON, or ASCELIN (d. 1030 or 1031), French bishop and poet, studied at Reims and became bishop of Laon in 977. When Laon was taken by Charles, duke of Lorraine, in 988, he was put into prison, whence he escaped and sought the protection of Hugh Capet, king of France. Winning the confidence of Charles of Lorraine and of Arnulf, archbishop of Reims, he was restored to his see; but he soon took the opportunity to betray Laon, together with Charles and Arnulf, into the hands of Hugh Capet. Subsequently he took an active part in ecclesiastical affairs, and died on the 19th of July 1030 or 1031. Adalberon wrote a satirical poem in the form of a dialogue dedicated to Robert, king of France, in which he showed his dislike of Odilo, abbot of Cluny, and his followers, and his objection to persons of humble birth being made bishops. The poem was first published by H. Valois in the Carmen panegyricum in laudem Berengarii (Paris, 1663), and in modern times by J. P. Migne in the Patrologia Latina, tome cxli. (Paris, 1844). Adalberon must not be confounded with his namesake, Adalberon, archbishop of Reims (d. 988 or 989).
