Nicolas Midi, licentiate in theology in 1424, was named by Henry VI as canon of Rouen on April 21, 1431, and he was installed there eleven days before the burning of Jeanne.

On June it, the canons accorded to him remission of the right of annates, as they had in the case of Jean Beaupère, "by special grace, because of the services he had rendered the Church." Nicolas Midi addressed King Henry VI upon his entry into Paris in December, 1431, as delegate of the University.

He was sent to the Council of Bâle in 1432, and became rector of the University of Louvain in 1433.

About 1434 he contracted leprosy and had to resign all his commissions and his canonicate, but he retained the revenues from them. Midi was still living on November 8, 1438A convinced Burgundian, (in 1416 he had debated in favor of the propositions of Jean Petit with the Nation of Normandy) he was a fanatic supporter of the University (from IV he was rector of the University of Paris).

A terrible malady that he contracted was early interpreted, and in an entirely legendary way, as the sign of divine punishment merited for his role in the Trial: for he was the author of the Twelve Articles summing up misleadingly the doctrine said to be Jeanne's, and he was one of Bedford's confidential friends.

(On May 12, 1432, out of regard for the Regent, the Chapter of Rouen decided that Nicolas Midi, sent to the Council of Bile, should receive the money distributions as if he were present.)

If Pierre Maurice did not wish to accept the commission of going to the Council, Nicolas Midi was urged to take his place. (Arch. de la Seine-Inférieure, G. 2126).
