The Refutation of All Heresies, Book 10

Now the Docetae advance assertions of this description: that the primal Deity is as a seed of the fig-tree; and that from this proceeded three AEons as the stem, and the leaves and the fruit; and that these projected thirty AEons, each (of them) ten; and that they were all united in decades, but differed only in positions, as some were before others. And (the Docetae assert) that infinite AEons were indefinitely projected, and that all these were hermaphrodites. And (they say) that these AEons formed a design of simultaneously going together into one AEon, and that from this the intermediate AEon and from the Virgin Mary they begot a Saviour of all.
