1 Such, then, is the account they give of what took place within the Pleroma; such the calamities that flowed from the passion which seized upon the Æon who has been named, and who was within a little of perishing by being absorbed in the universal substance, through her inquisitive searching after the Father; such the consolidation [of that Æon] from her condition of agony by Horos, and Stauros, and Lytrotes, and Carpistes, and Horothetes, and Metagoges. Such also is the account of the generation of the later Æons, namely of the first Christ and of the Holy Spirit, both of whom were produced by the Father after the repentance [of Sophia], and of the second Christ (whom they also style Saviour), who owed his being to the joint contributions [of the Æons].
They tell us, however, that this knowledge has not been openly divulged, because all are not capable of receiving it, but has been mystically revealed by the Saviour through means of parables to those qualified for understanding it. This has been done as follows. The thirty Æons are indicated (as we have already remarked) by the thirty years during which they say the Saviour performed no public act, and by the parable of the labourers in the vineyard. Paul also, they affirm, very clearly and frequently names these Æons, and even goes so far as to preserve their order, when he says, “To all the generations of the Æons of the Æon.” Nay, we ourselves, when at the giving of thanks we pronounce the words, “To Æons of Æons” (for ever and ever), do set forth these Æons.
And, in fine, wherever the words Æon or Æons occur, they at once refer them to these beings.
