Nicholas of Clémanges

Mathieu-Nicolas Poillevillain de Clémanges (or Clamanges) (born in Champagne c. 1360, died in Paris between 1434 and 1440) was a French humanist and theologian.

He made his studies in the Collège de Navarre, University of Paris, and in 1380 received the degree of Licentiate, and then later received a Master of Arts. He studied theology under Jean Gerson and Pierre d'Ailly, and received the degree of Bachelor of Theology in 1393.

He had begun to lecture at the university in 1391 and was appointed its rector in 1393, a position he filled until 1395. The Church was then agitated by the Western Schism, and three methods were proposed to re-establish peace: compromise, concession, and a general .

From 1380 to 1394 the University of Paris advocated a general council. In 1394 another tendency was manifest; i.e. both Pope Boniface IX and Pope Clement VII were held responsible for the continuance of the schism, and their resignations decreed to be the means of obtaining peace. To this end a letter was written to King Charles VI by three of the most learned masters of the university, d'Ailly, Clémanges, and Gilles des Champs. Des Champs and d'Ailly prepared the content, to which Clémanges gave a Ciceronian elegance of form. The letter was unsuccessful, and the university was ordered to abstain from further discussion.

Clémanges, forced to resign the rectorship of the university, then became canon and dean of Saint-Clodoald in 1395, and later on canon and treasurer of Langres. The antipope Benedict XIII, who admired his Latin style, took him for his secretary in 1397, and he remained at Avignon until 1408, when he abandoned Benedict because of the latter's conflict with Charles VI.
