The Refutation of All Heresies

It has been easily made evident to all, that the heresy of the Peratae is altered in name only from the (art) of the astrologers. And the rest of the books of these (heretics) contain the same method, if it were agreeable to any one to wade through them all. For, as I said, they suppose that the causes of the generation of all begotten things are things unbegotten and superjacent, and that the world with us has been produced after the mode of emanation, which (world) they denominate formal.

And (they maintain) that all those stars together which are beheld in the firmament have been causes of the generation of this world. They have, however, altered the name of these, as one may perceive from the Proastioi by means of a comparison (of the two systems). And secondly, according to the same method as that whereby the world was made from a supernal emanation, they affirm that in this manner objects here derive from the emanation of the stars their generation, and corruption, and arrangement.

Since, then, astrologers are acquainted with the horoscope, and meridian, and setting, and the point opposite the meridian; and since these stars occupy at different times different positions in space, on account of the perpetual revolution of the universe, there are (necessarily) at different periods different declinations towards a centre, and (different) ascensions to centres. (Now the Peratic here-ties), affixing an allegorical import to this arrangement of the astrologers, delineate the centre, as it were, a god and monad and lord over universal generation, whereas the declination (is regarded by them as a power) on the left, and ascension on the right.

When any one, therefore, falling in with the treatises of these (heretics), finds mention among them of right or left power, let him recur to the centre, and the declination, and the ascension (of the Chaldean sages, and) he will clearly observe that the entire system of these (Peratae) consists of the astrological doctrine.
