But the followers of Ptolemy say ¹ that he [Bythus] has two consorts, which they also name Diatheses (affections), viz., Ennoea and Thelesis. For, as they affirm, he first conceived the thought of producing something, and then willed to that effect. Wherefore, again, these two affections, or powers, Ennoea and Thelesis, having intercourse, as it were, between themselves, the production of Monogenes and Aletheia took place according to conjunction. These two came forth as types and images of the two affections of the Father,--visible representations of those that were invisible,--Nous (i.e., Monogenes) of Thelesis, and Aletheia of Ennoea, and accordingly the image resulting from Thelesis was masculine, ² while that from Ennoea was feminine. Thus Thelesis (will) became, as it were, a faculty of Ennoea (thought). For Ennoea continually yearned after offspring; but she could not of herself bring forth that which she desired. But when the power of Thelesis (the faculty of will) came upon her, then she brought forth that on which she had brooded.
