(Ἀνθίμος), bishop of Trapezus in Pontus, was made patriarch of Constantinople by the influence of the empress Theodora (A. D. 535), and about the same time was drawn over to the Eutychian heresy by Severus. Soon after his election to the patriarchate, Agapetus, the bishop of Rome, came to Constantinople, and obtained from the emperor Justinian a sentence of deposition against Anthimus, which was confirmed by a synod held at Constantinople under Mennas, the successor of Anthimus. (A. D. 536; Novell. 42; Mansi, Nova Collect. Concil. viii. pp. 821, 869, 1149-1158; Labbe, v.; AGAPETUS.) Some fragments of the debate between Anthimus and Agapetus in the presence of Justinian are preserved in the Acts of the Councils.
