a Greek theologian, was priest of the metropolitan church of Antioch, and destined to succeed Flavian, bishop of that place. Porphyry, who desired to obtain this episcopal see, by intrigue at the court of Constantinople obtained of Arcadius an order of exile against Constantinus, who, by the aid of his friends, escaped to Cyprus, where he appears to have passed the remainder of his days. He died about 410 of the Christian aera. He placed in order the thirty-four Homilies of John Chrysostom, upon the epistle to the Hebrews. Among the letters of Chrysostom there are two addressed to Constantinus, and he appears to be the author of two other letters attributed generally to Chrysostom. See Hoefer, Nouv. Biog. Generale, s.v.
