QUADRATUS, APOLOGIST. — Eusebius (Hist. eccl., IV, 23, 3) knows through Dionysius of Corinth a certain Bishop Q. of Athens, successor of the Bishop and Martyr Publius. This Q., who lived under Marcus Aurelius, has nothing to do with another Q. mentioned by Eusebius among the orthodox prophets (ibid., III, 37, 1 alongside Philip’s daughters; V, 17, 2, 3, 4 alongside the prophetess Ammia in Philadelphia; the source of the last notice is the anti-Montanist author).
This Q., a prophet and disciple of the Apostles, probably lived in Asia Minor. He is often identified with the author of an Apology addressed to the Emperor Hadrian (ibid., IV, 3, 1). This identification is unlikely, however, because the author of the Apology appears to have been conversant with rhetorical and juridical language. The phrase in Eusebius: “Apology for our religion” may have been taken from the text, as may the following phrase: “because certain evil persons sought to molest (ἐννοήσει) our people.” If one compares the *spesma* of the Delian Jews on behalf of the Jews in Josephus, *Antig.*, XIV, 10, 14 (232), one will note the technical character of these expressions, which makes it unlikely that the “prophet” Q. would have been able to employ such language. Of the Apology of Q. only a small fragment has been preserved, in Eusebius (ibid., IV, 3, 2), in which the author speaks of persons raised from the dead by Jesus who lived on until his own time. To this fragment is related Fragment XI of Papias (ed. Fr. X. Funk, *Opera PP. Apostolici*, I, Tübingen 1901, pp. 366 ff.) taken from Philip of Side, according to which Papias would have spoken of persons raised from the dead by Jesus and living on until his own time.
