Personal details
Died31 March 1462


Little is known about the life and the patriarchate of Isidore except that he was an ethnic Greek and member of Greek community in Istanbul. His surname derives from the Xanthopoulon monastery in Istanbul which he entered, becoming a hieromonk and later rising to be its abbot.[2] Isidore worked alongside Gennadius Scholarius during the Council of Florence[3] and was one of the signatories of a 1445 document against the East-West Union of Churches.[4] In this period Isidore was deemed the spiritual father of the Greek community in Istanbul.[3] Immediately prior to his election, he was serving as the Metropolitan bishop of Heraclea.[5]

After the resignation of Gennadius Scholarius as Patriarch in mid-January 1456, Isidore was elected to succeed him. He obtained the confirmation from Sultan Mehmed II and he was consecrated bishop in the Pammakaristos Church.[6]

His reign lasted up to his death on 31 March 1462,[2] and he was succeeded by Joasaph I.[1]
