Nicholas of Clairvaux, also Nicholas of Montiéramey[1] (French: Nicolas de Clairvaux, Nicolas de Montiéramey; b and d 12th century) was a French Benedictine monk who later became a Cistercian monk.
Nicholas entered the monastic life at Montiéramey Abbey, a Benedictine monastery near Troyes in Champagne.
Despite the disgrace of having been dismissed by Bernard, he succeeded in gaining the good opinion of Count Henry I of Champagne, whose service he entered.
[5] Nicholas was the author of letters[6] and of sermons characterised by the use of rare terms, the striving for a high-flown style without genius, and a tendency to plagiarism.
[7] He is noted for having attributed to himself several texts and sermons by other authors, particularly Hugues de Saint-Victor (Adnotationes in Psalmos), and above all Saint Bernard, at least 19 of whose sermons were claimed by Nicholas as his own.
