[Sidenote: p. 327.] And of another number they say this:--the element Eta with the Episemon is an ogdoad, as it lies in the 8th place from the Alpha. Then again counting the numbers of the same elements together without the Episemon and adding them together as far as the Eta, they display the number 30. For if one begins the number of the elements with the Alpha (and continues) up to the Eta (inclusive) after subtracting the Episemon, one finds the number 30.[273] Since then the number 30 is made from the uniting of the three powers, the same number 30 occurring thrice made 90--for three times 30 are 90 [and the same triad multiplied into itself brought forth 9]. Thus the ogdoad made the number 99 from the first ogdoad and decad and dodecad. The number of which (ogdoad) they sometimes carry to completion[274] and make a triacontad and sometimes deducting the 12th number they count it 11 and likewise make the 10th (number) 9. And multiplying and decupling[275] [Sidenote: p. 328.] these (figures) they complete the number 99. And since the 12th Aeon left the 11 [on high] and fell away from them and came below, they imagine that these things correspond one to the other. For the type of the letters is instructive. For the 11th letter is the Lambda which is the number 30 and is so placed after the likeness of the arrangement on high,[276] since from the Alpha apart from the Episemon, the number of the same letters up to Lambda when added together makes up the number 99.[277] But (they say) that the Lambda which is put in the 11th place[278] came down to seek for what is like unto it so that it may complete the 12th number, and having found it did (so) complete it is plain from the very shape of the element.[279] For the Lambda succeeding as it were in the search for what was like unto itself and finding, seized it, and filled up with it the place of the 12th element Mu, which is composed of two Lambdas.[280] Wherefore they avoid by this gnosis the place [Sidenote: p. 329.] of the 99 that is to say the Hysterema[281] as the type of the left hand, but follow the One which added to the 99, brings them over to the right hand.
