ANATOLIUS, Patriarch of Constantinople. - Born in Alexandria, died on 3 July 458. The patriarch Dioscorus had him raised to the see of Constantinople, which he occupied from Dec. 449 to 3 July 458. At the Council of Constantinople (21 Oct. 450), in the presence of four legates of the Pope, he subscribed to the pontifical Letter to Flavian, known as the Tome of Leo. (For a Syriac fragment of the lost acts of the Council cf. P. Mouterde, in Miscellanea dell'Università di Beirut, 15 [1930], pp. 33-50; and for the Tome of Leo cf. Leonis Epist., 80, 85; PL 54, 912-922). At the Council of Chalcedon, which convened immediately afterwards (Oct. 451), he approved the deposition of Dioscorus; he was a member of the commission that compiled the definitive formula of faith of the Council; he approved the famous 28th canon on the privileges of the see of Constantinople and wrote personally to the Pope to ask for its confirmation (Epistola ad Leonem, 4; PL 54, 984 A). It is known, however, that his efforts, like those of the Fathers of the council and of the emperor in the same matter, were in vain (v. CALCEDONIA).
After the Council of Chalcedon, A.'s relations with Pope Leo were rather tense. Having deposed the archdeacon Aetius from his office in order to replace him with a certain Andrew, suspected of Eutychianism, the Pope reproved him for it, and ordered and obtained that Aetius be reinstated in his office. The question of the two Eutychian priests, Atticus and Andrew, was the subject of negotiations between Leo and A. when the latter died. If on the one hand A.'s praiseworthy zeal in making the Chalcedonian orthodoxy triumph against the Monophysites of Egypt earned him the Pope's congratulations with exhortations to vigilance, on the other hand it is certain that St. Leo had only mediocre confidence in him. The Byzantines made of him a saint and at the same time a martyr, and they celebrate his feast on 3 July.
