Simon du Bosc

[3] Originally from an old family of Rouen, he was son of Mathieu du Bosc, and was a doctor in canon law.

[citation needed] In 1407 King Charles VI appointed him one of the ambassadors who negotiated the interview of Savona between Popes Benedict XIII and Gregory XII, in order to put an end to the Great Western Schism, which failed.

He preached several times against the practice of the Eucharist advocated by John Hus and distinguished himself by his zeal for the unity of the Church and the struggle against heresies.

The council managed to resolve the crisis in 1417 after the deposition of the popes of Pisa and Avignon and the resignation of that of Rome, Gregory XII.

[citation needed] Simon died in Paris on 14 September 1418 while the war between the Kings of France and England was ravaging Normandy.
