member of the French royalty without the request or consent of the King. He was consecrated a bishop in January 1440. In 1440 he was briefly administrator of the diocese of Conserans (St. Lizier) The following year he was additionally appointed Administrator of the Dioceses of Béziers and Nîmes. In 1443, Cardinal d'Estouteville was appointed Archpriest of the Basilica Liberiana (Santa Maria Maggiore) by Pope Eugene IV, in succession to Cardinal Niccolò Albergati, who had died on 9 May 1443. He held the position for life. In March 1451 Pope Nicholas V granted a new set of Statutes to the Canons of the Basilica, which emphasized the decisive power that the Archpriest had over the physical structure of the church and its property. In his Testament d'Estouteville left funds for the refurbishment and redecoration of the Chapel of S. Michele e S. Pietro in Vincoli, and for the building of the Chapel of S. Antonio. On 7 January 1450 D'Estouteville was appointed Administrator of the Diocese of Lodève. He served in this office for three years, before being appointed bishop of the Diocese of Saint-Jean-de-Maurienne in Savoy. He was Bishop of Maurienne from 26 January 1453 to 20 April 1453, though he continued to act as Administrator of the diocese for the rest of his life. In April 1453 he was released from his obligation as Bishop of Maurienne and appointed Archbishop of Rouen by Nicholas V. The Canons of Rouen protested the violation of their rights, and Pope Nicholas granted them an Indult on 16 November promising them that, on the death of Guillaume d'Estouteville, they could elect whomever they wished. D'Estouteville took possession of the diocese of Rouen on 30 April 1453 through a Procurator, Bishop Louis d'Harcourt of Narbonne. Diplomat On 13 August 1451 Cardinal d'Estouteville was sent to France as legate by Pope Nicholas V, at the instigation of the Duc de Bourbon, to make peace between King Charles VII of France and England; at the same time Cardinal Nicholas of Cusa was sent to England on the same mission. Both failed. At the behest of the Inquisitor General Jean Brehal, Estouteville undertook an ex officio revision of the trial of Joan of Arc. He afterwards reformed the statutes of the University of Paris, issuing his decree on 1 June 1452. He shortened the course leading to the Doctorate in theology from fifteen to fourteen years,
