1911 Encyclopædia Britannica/Alger of Liége
ALGER OF LIÉGE (d. c. 1131), known also as Alger of Cluny and Algerus Magister, a learned French priest who lived in the first half of the 12th century. He was first a deacon of the church of St Bartholomew at Liége, his native town, and was then appointed (c. 1100) to the cathedral church of St Lambert. He declined many offers from German bishops and finally retired to the monastery of Cluny, where he died about 1131 at a great age and leaving a good reputation for piety and intelligence. His History of the Church of Liége, and many of his other works, are lost. The most important of those still extant are: 1. De Misericordia et Justitia, a collection of biblical and patristic extracts with a commentary (an important work for the history of church law and discipline), which is to be found in the Anecdota of Martène, vol. v. 2. De Sacramentis Corporis et Sanguines Domini; a treatise, in three books, against the Berengarian heresy, highly commended by Peter of Cluny and Erasmus. 3. De Gratia et Libero Arbitrio; given in B. Pez's Anecdota, vol. iv. 4. De Sacrificio Missae; given in the Collectio Scriptor. Vet. of Angelo Mai, vol. ix. p. 371.
