They maintain, then, that in the invisible and ineffable heights above there exists a certain perfect, pre-existent Æon, whom they call Proarche, Propator, and Bythus, and describe as being invisible and incomprehensible. Eternal and unbegotten, he remained throughout innumerable cycles of ages in profound serenity and quiescence. There existed along with him Ennœa, whom they also call Charis and Sige. At last this Bythus determined to send forth from himself the beginning of all things, and deposited this production (which he had resolved to bring forth) in his contemporary Sige, even as seed is deposited in the womb. She then, having received this seed, and becoming pregnant, gave birth to Nous, who was both similar and equal to him who had produced him, and was alone capable of comprehending his father's greatness. This Nous they call also Monogenes, and Father, and the Beginning of all Things. Along with him was also produced Aletheia; and these four constituted the first and first-begotten Pythagorean Tetrad, which they also denominate the root of all things. For there are first Bythus and Sige, and then Nous and Aletheia. And Monogenes, perceiving for what purpose he had been produced, also himself sent forth Logos and Zoe, being the father of all those who were to come after him, and the beginning and fashioning of the entire Pleroma. By the conjunction of Logos and Zoe were brought forth Anthropos and Ecclesia; and thus was formed the first-begotten Ogdoad, the root and substance of all things, called among them by four names, viz., Bythus, and Nous, and Logos, and Anthropos. For each of these is masculo-feminine, as follows: Propator was united by a conjunction with his Ennœa; then Monogenes, that is Nous, with Aletheia; Logos with Zoe, and Anthropos with Ecclesia.
