for Book I, besides being harmless, it had possibly by that time become too firmly connected with the name of Origen for its attribution to this other sufferer in the Maximinian persecution to be disturbed in later times. It only remains to see how this theory fits in with the remarks of Photius given above. It is fairly evident that Photius is speaking from recollection only, and that the words do not suggest that he had Hippolytus’ actual work before him when writing, while he throughout speaks of it in the past tense as one might speak of a document which has long since perished, although some memory of its contents have been preserved. If this were so, we might be prepared to take Photius’ description as not necessarily accurate in every detail; yet, as we have it, it is almost a perfect description of our text. The 32 heresies, as we have shown above, appear in our text as in Photius’ document. Our text contains not only the large excerpts from Irenæus which we might expect from Photius’ account of its inception, but also the “refutations” which do not appear in the _Adversus Omnes Hæreses_. It extends “up to,” as Photius says, Noetus and the Noetians, and although it does not contain any mention of Dositheus or the Dositheans, this may have been given in the part which has been cut out of Book X.[67] If that were the case, or if Photius has made any mistake in the matter, as one might easily do when we consider that all the early heresiologies begin with Jewish and Samaritan sects, the only real discrepancy between our text and Photius’ description of Hippolytus’ work is in the matter of length. But it is by no means certain that Photius ever saw the whole work put together, and it is plain that he had never seen or had forgotten the first four books dealing with the philosophers, the mysteries and the charlatans. Without these, and without the summary, Books V to IX do not work out to more than 70,000 words in all, and this might well seem a mere “booklet” to a man then engaged in the compilation of his huge _Bibliotheca_. Whether, then, Hippolytus did or did not reduce to writing the exposition of heresies which he made in his youth, it seems probable that all certain trace of this exposition is lost. It is certainly not to be recognized in pseudo-Tertullian’s _Adversus Omnes Hæreses_, and the work of Hippolytus recorded by Photius was probably a copy of our text in a more or less complete form. 5. THE STYLE OF THE WORK
