With great ingenuity J.B. Lightfoot, in Clement of Rome (London, 1890), has found traces of this list of Popes in Epiphanius of Cyprus, Haer., xxvii, 6, where that fourth century writer carelessly says: "Marcellina came to us lately and destroyed many, in the days of Anicetus, Bishop of Rome", and then refers to "the above catalogue", though he has given none. He is clearly quoting a writer who was at Rome in the time of Anicetus and made a list of popes beginning with St. Peter and St. Paul, martyred in the twelfth year of Nero. A list which has some curious agreements with Epiphanius, and extends only to Anicetus, is found in the poem of Pseudo-Tertullian against Marcion; the author has mistaken Marcellina for Marcion. The same list is at the base of the earlier part of the Liberian Catalogue, doubtless from Hippolytus. It seems fairly certain that the list of Hegesippus was also used by Irenaeus, Africanus, and Eusebius in forming their own. It should be said that a number of scholars have rejected Lightfoot's view, though on weak grounds. It is probable that Eusebius borrowed his list of the early bishops of Jerusalem from Hegesippus.
Eusebius quotes from Hegesippus a long and perhaps legendary account of the death of James the Just, "the brother of the Lord", also the story of the election of his successor Simeon, and the summoning of the descendants of Jude to Rome by Domitian. A list of heresies against which Hegesippus wrote is also cited. Dr. Lawlor has argued (Hermathena, XI, 26, 1900, p. 10) that all these passages cited by Eusebius were connected in the original, and were in the fifth book of Hegesippus. He has also argued (Journal of Theological Studies, April, 1907, VIII, 436) the likelihood that Eusebius got from Hegesippus the statement that John was exiled to Patmos by Domitian. Hegesippus mentioned the letter of Clement to the Corinthians, apparently in connection with the persecution of Domitian. It is very likely that the dating of heretics according to papal reigns in Irenaeus and Epiphanius -- e.g., that Cerdon and Valentius came to Rome under Anicetus -- was derived from Hegesippus, and the same may be true of the assertion that Hermas was the brother of Pope Pius (as the Liberian Catalogue, the poem against Marcion, and the Muratorian fragment all state). The date of Hegesippus is fixed by the statement that the death and apotheosis of Antinous (130) occured in his own time, that he came to Rome under Anicetus and wrote in the time of Eleutherus. Zahn (Zeitschrift für Kirchengeschichte, II [1877-8], 288, and in Theol. Litteraturblatt , 495) has shown that the work of Hegesippus was still extant in the sixteenth and seventeenth centuries in three Eastern libraries.
