Note 5 — BOOK X SUMMARIES, AND THE WORD OF TRUTH
Francis Legge translation
Book I only is concerned with the teachings of the Greek philosophers; but Books II and III must, according to the promise in Vol. I, pp. 63, 64, have contained an exposition of the mystic rites and astrological doctrine, and Book IV is entirely taken up with magic and divination. This is confirmed by the statement in Vol. I, p. 119. Hippolytus must therefore have forgotten this when writing Book X, or at any rate did not have the earlier Books before him.
