A Dictionary of Greek and Roman biography and mythology

(Ἀδαμάντιος), an ancient physician, bearing the title of Iatrosophista (ἰατρικῶν λόγων σοφιστής, Socrates, Hist. Eccles. 7.13), for the meaning of which see Dict. of Ant. p. 507. Little is known of his personal history, except that he was by birth a Jew, and that he was one of those who fled from Alexandria, at the time of the expulsion of the Jews from that city by the Patriarch St. Cyril, A. D. 415. He went to Constantinople, was persuaded to embrace Christianity, apparently by Atticus the Patriarch of that city, and then returned to Alexandria. (Socrates, l.. c.)
