Note 163 — BOOK VII BASILIDES, SATURNILUS, AND OTHERS

There is no indication of the source from which Hippolytus drew the material for this chapter. It does not seem to have been the writings of Irenæus, for his remarks in I, xxv tell us even less about Marcion than our text. Possibly Hippolytus was here indebted to the work of Justin Martyr, which seems to have been extant in the time of Photius. With the exception of the notice of Prepon, our text contains nothing that was not known otherwise.
