Where Eusebius secured the information that the Carpocratians made the magic rites of Simon public, instead of keeping them secret, as Basilides had done, I cannot tell. None of our existing sources mentions this fact, and whether Eusebius took it from some lost source, or whether it is simply a deduction of his own, I am not certain. In other respects his account agrees closely with that of Irenæus. It is possible that he had seen the lost work of Hippolytus (see below, VI. 22, note 9), and from that had picked up this item which he states as a fact. But the omission of it in Philaster, Pseudo-Tertullian, and Epiphanius are against this supposition. Justin’s Syntagma Eusebius probably never saw (see below, chap. 11, note 31).
