Reading edition
Examples are the accounts of Basilides in Clement of Alexandria and Hippolytus, compared with those in Irenæus and Epiphanius; and the accounts of the Ophites in Hippolytus, compared with those of Irenæus and Epiphanius. The literature of the subject is considerable: see especially A. Hilgenfeld, die Ketzergeschichte des Urchristenthums (e.g. p. 202); R. A. Lipsius, zur Quellenkritik des Epiphanios; and A. Harnack, zur Quellenkritik der Geschichte des Gnosticismus.
