Liborius ST., fourth bishop of Manes, a disciple of St. Pavacius, flourished from the middle to the close of the 4th century. The existing documents on his life are quite untrustworthy, and relate only that he was a pious man, performed sundry miracles, and that he was a fast friend of St. Martin of Tours. See the Bollandists for July 23; Tillemont, Memoires, 10:307; Mabillon, De Pontif. Cenomasnnensibus. His body was transferred in the 9th century from Mans to Paderborn by order of Biso, bishop of the latter place. See Pertz, Script. 4 (6), 149 sq.; Herzog, Real-Encyklopädie, 7:380.
