Library Hippolytus Refutation of All Heresies
Book 5, Chapter 13: The Peratic Heresy Not Generally Known.
But since I consider that I have plainly explained the Peratic heresy, and by many (arguments) have rendered evident (a system that hitherto) has always escaped notice, and is altogether a tissue of fable, and one that disguises its own peculiar venom, it seems expedient to advance no further statement beyond those already put forward; for the opinions propounded by (the heretics) themselves are sufficient for their own condemnation.
