There are some who do not claim the first place for Bythus, but only a lower one. They put their Ogdoad in the foremost rank; itself, however, derived from a Tetrad, but under different names. For they put Pro-arche (Before the Beginning) first, Anennoetos (Inconceivable) second, Arrhetos (Indescribable) third, Aoratos (Invisible) fourth. Then after Pro-arche they say Arche (Beginning) came forth and occupied the first and the fifth place; from Anennoetos came Acataleptos (Incomprehensible) in the second and the sixth place; from Arrhetos came Anonomastos (Nameless) in the third and the seventh place; from Aoratos [6919] came Agennetos (Unbegotten) in the fourth and the eight place. Now by what method he arranges this, that each of these Æons should be born in two places, and that, too, at such intervals, I prefer to be ignorant of than to be informed. For what can be right in a system which is propounded with such absurd particulars?
