4 The Father afterwards produces, in his own image, by means of Monogenes, the above-mentioned Horos, without conjunction, masculo-feminine. For they maintain that sometimes the Father acts in conjunction with Sige, but that at other times he shows himself independent both of male and female. They term this Horos both Stauros and Lytrotes, and Carpistes, and Horothetes, and Metagoges. And by this Horos they declare that Sophia was purified and established, while she was also restored to her proper conjunction. For her enthymesis (or inborn idea) having been taken away from her, along with its supervening passion, she herself certainly remained within the Pleroma; but her enthymesis, with its passion, was separated from her by Horos, fenced off, and expelled from that circle. This enthymesis was, no doubt, a spiritual substance, possessing some of the natural tendencies of an Æon, but at the same time shapeless and without form, because it had received nothing. And on this account they say that it was an imbecile and feminine production.
