[Sidenote: p. 304.] 39. But the adherents of Ptolemy say that he [Bythos] has two partners whom they call also (his) predispositions[176] (_i. e._) Thought and Will. For he first had it in mind to project something, and then he willed (to do so). Wherefore from these two diatheses and powers, that is, from Ennoia and Thelesis as it were blending with one another, the projection of Monogenes and Aletheia as a pair came to pass. The which types and images of the two diatheses of the Father came forth visible from the invisible, Nous from Thelema[177] and Aletheia from Ennoia. Therefore also the male image was born from the later-begotten Thelema, but the female from the unbegotten Ennoia, because Thelema came into being like a power from Ennoia. For Ennoia has ever in mind projection, but she is not able by herself to project what she has in mind. But when the power of Thelema [came into being later],[178] then she projected what she had in mind. 5. _About Marcus._[179] 40. And a certain other teacher of theirs, Marcus, an [Sidenote: p. 305.] expert in magic, depending now on trickery and now on demons, leads astray many. For he says that there is in him the greatest power from the invisible and unnameable places. And often he takes a cup, as if consecrating it,[180] and prolonging the words of consecration, causes the mixture to appear purple and sometimes red, so as to make his dupes think that a certain grace has come down, and has given a blood-like power[181] to the draught. But the rogue, though he formerly escaped the notice of many, will, now that he has been refuted,[182] have to stop. For he used secretly to insert a certain drug having the power of giving such a colour to the mixture, and then to wait while uttering much gibberish, until it dissolved by absorbing moisture and, mixing with the draught, coloured it. And the drugs which can thus give colour we have before described in our book against the Magicians,[183] and have set forth how leading many astray, they utterly ruin them. Which (last), if they care to consider more carefully what has been said above, will know the fraud of Marcus.
