5 Others still, however, have called their primary and first-begotten Ogdoad by the following names: first, Proarche; then Anennoetos; thirdly, Arrhetos; and fourthly, Aoratos. Then, from the first, Proarche, there was produced, in the first and fifth place, Arche; from Anennoetos, in the second and sixth place, Acataleptos; from Arrhetos, in the third and seventh place, Anonomastos; and from Aoratos, in the fourth and eighth place, Agennetos. This is the Pleroma of the first Ogdoad. They maintain that these powers were anterior to Bythus and Sige, that they may appear more perfect than the perfect, and more knowing than the very Gnostics! To these persons one may justly exclaim: “O you trifling sophists!” since, even respecting Bythus himself, there are among them many and discordant opinions. For some declare him to be without a consort, and neither male nor female, and, in fact, nothing at all; while others affirm him to be masculo-feminine, assigning to him the nature of a hermaphrodite; others, again, allot Sige to him as a spouse, that thus may be formed the first conjunction.
