7 He employed as his instrument, as the Sige of Marcus declares, the power of seven letters, in order that the fruit of the independent will [of Achamoth] might be revealed. “Consider this present Episemon,” she says— “Him who was formed after the [original] Episemon, as being, as it were, divided or cut into two parts, and remaining outside; who, by His own power and wisdom, through means of that which had been produced by Himself, gave life to this world, consisting of seven powers, after the likeness of the power of the Hebdomad, and so formed it, that it is the soul of everything visible.
And He indeed uses this work Himself as if it had been formed by His own free will; but the rest, as being images of what cannot be [fully] imitated, are subservient to the Enthymesis of the mother. And the first heaven indeed pronounces Alpha, the next to this Epsilon, the third Eta, the fourth, which is also in the midst of the seven, utters the sound of Iota, the fifth Omicron, the sixth Upsilon, the seventh, which is also the fourth from the middle, utters the elegant Omega,”— as the Sige of Marcus, talking a deal of nonsense, but uttering no word of truth, confidently asserts.
“And these powers,” she adds, “being all simultaneously clasped in each other's embrace, do sound out the glory of Him by whom they were produced; and the glory of that sound is transmitted upwards to the Propator.” She asserts, moreover, that “the sound of this uttering of praise, having been wafted to the earth, has become the Framer and the Parent of those things which are on the earth.”
