Hippolytus

“ Just as the pupil of the eye appears dark beneath the underlying humours, but is illuminated by the spirit, so the darkness earnestly strives after the spirit, and has with itself all the powers which wish to retire and return. ”

“ And the essences of the principles, the Sethians say, are light and darkness. And in the midst of these is pure spirit; and the spirit, they say, is that which is placed intermediate between darkness, which is below, and light, which is above. It is not spirit, as a current of wind or a certain gentle breeze which may be felt, but just as if some fragrance of ointment or incense made out of a refined mixture,—a power diffusing itself by some impulse of fragrance which is inconceivable and superior to what one can express. ”

“ And the Sethians say that from the water was produced a first-begotten principle, namely a vehement and boisterous wind, and that it is a cause of all generation, which creates a sort of heat and motion in the world from the motion of the waters. And they maintain that this wind is fashioned like the hissing of a serpent into a perfect image. And on this the world gazes and hurries into generation, being inflamed as a womb; and from thence they are disposed to think that the generation of the universe has arisen. ”
