Note 56 — BOOK X SUMMARIES, AND THE WORD OF TRUTH
Francis Legge translation
Here he omits the heresies of the Quartodecimans and the Encratites, which receive notice in Book VIII, pp. 113, 115, 116 supra, and passes on to Marcion, who was a contemporary of Valentinus. It is plain, therefore, that he does not attempt in the summary to keep either to order of date or to that of the earlier books.
