ARNOLDO of BOHÉRIES. - Cistercian monk of Bohéries (diocese of Laon, now Soissons), who probably lived at the end of the 12th century. He became famous only when B. Tissier, the editor of the *Bibliotheca Patrum Cisterciensium* (vol. VI, Bonnefontaine 1664, p. 138), followed by J. Mabillon, Migne, etc., attributed to him the *Speculum Monachorum*, also called *Speculum Bernardi*.
A very brief but substantial work (PL 184, 1175-78), *brevis formula sanctae et bonae conversationis*, this summary of spirituality (which explicitly refers to the Rule of St. Benedict) offers advice on psalmody, spiritual reading, manual labor, and particularly emphasizes examination of conscience, private confession, and—“summa philosophia”—assiduous meditation on death. Its influence on later monastic circles was considerable.
