Hippolytus

“ For the blood is converted into seed and milk, and this power becomes mother and father—father of those things that are in process of generation, and the augmentation of those things that are being nourished ”

“ He has stood above in unbegotten power. He stands below, when in the stream of waters He was begotten in a likeness. He is to stand above, beside the blessed indefinite power, if He be fashioned into an image. ”

“ Of all things, (i.e.) of whatsoever there is a generation, the beginning of the desire of the generation is from fire. Wherefore the desire after mutable generation is denominated “to be inflamed.” For when the fire is one, it admits of two conversions. For, he says, blood in the man being both warm and yellow, is converted as a figured flame into seed; but in the woman this same blood is converted into milk. And the conversion of the male becomes generation, but the conversion of the female nourishment for the fœtus. ”
