Book V. ———————————— Contents. The following are the contents of the fifth book of the Refutation of all Heresies : 313 — What the assertions are of the Naasseni, who style themselves Gnostics, and that they advance those opinions which the Philosophers of the Greeks previously propounded, as well as those who have handed down mystical (rites), from (both of) whom the Naasseni taking occasion, have constructed their heresies. And what are the tenets of the Peratæ, and that their system is not framed by them out of the holy Scriptures, but from astrological art . What is the doctrine of the Sethians, 314 and that, purloining 315 their theories from the wise men among the Greeks, they have patched together their own system out of shreds of opinion taken from Musæus, and Linus, and Orpheus. What are the tenets of Justinus, and that his system is framed by him, not out of the holy Scriptures, but from the detail of marvels furnished by Herodotus the historian. 313     [Consult Bunsen, vol. i. p. 35, always interesting and ingeniously critical; nobody should neglect his work. But for a judicial mind, compare Dr. Wordsworth, p. 182.] 314     The ms. employs the form Sithians, which is obviously not the correct one. 315     This term κλεψίλογος is frequently applied by Hippolytus to the heretics.
