Jean d'Arces

Jean d'Arces was born in Montiers, the son of a noble family.[1] He became a licentiate in canon law.[1] After serving as prior of the Saint-Valentin monastery in Bissy, Savoy, he succeeded his uncle Hugues d'Arces as prior of the Great St Bernard Hospice, holding that position from 1419 to 1438.[1]

On February 28, 1438, he was elected Archbishop of Tarentaise, a post he held until his death.[1] He took part in the Council of Florence (1431–45) as the representative of Cardinal Louis Aleman.[1] While there, he participated in the papal conclave of November 5, 1439, where he supported the election of Antipope Felix V.[1]

Antipope Felix V created him a pseudocardinal in Geneva on April 6, 1444, awarding him the titular church of Santi Nereo e Achilleo.[1] He later submitted to Pope Nicholas V and was absolved for having supported Felix.[1] Pope Nicholas V made him a cardinal in the consistory of December 19, 1449, confirming his possession of Santi Nereo e Achilleo the next day.[1]

He died in Montiers on December 12, 1454.[1] He is buried in Montiers.[1]
