Bishop of Aquileia in Istria; he was one of the hundred and twenty five Western bishops who attended the Council of Rome at Easter, 680, and who subscribed the decree condemning monotheletism: Riedinger, p. 154, line 9 (= Mansi XI 311- 312) (Ἀγάθων ἐλάχιστος ἐπίσκοπος τῆς ἁγίας ἐκκλησίας Ἀκυλίας ἐπαρχίας Ἰστρίας; the old Latin version printed in Riedinger, p. 155, 7, calls his see "sanctae ecclesiae Aquiliensis prouinciae Istriae"). Agathon was a native of Iustinopolis in Istria; he was patriarch of Grado for ten years; he succeeded Stephanos 155 and was succeeded by Christophoros 53: Chron. Alt., p. 124 (Agathon patriarcha, qui fuit nacione Iustinopolis Caput Ystrie civitatis, sedit in patriarchatu ann. X). Patriarch of Grado; he succeeded Stephanos 155: John the Deacon, Cron. Ven., p. 88. He died after ruling the church for ten years and was succeeded by Christophoros 53: John the Deacon, Cron. Ven., p. 89. Possibly in office from 672 to 682; cf. Christophoros 53.
