Sige, however, was no true consort of Bythus, who included in himself the idea of male and female, and was the one cause of all things: comp. Hippolytus, Philosop., vi. 29. There seems to have been considerable disagreement among these heretics as to the completion of the mystical number thirty. Valentinus himself appears to have considered Bythus as a monad, and Sige as a mere nonentity. The two latest Æons, Christ and the Holy Spirit, would then complete the number thirty. But other Gnostic teachers included both Bythus and Sige in that mystical number.
