syzygy

In many Gnostic systems, the various emanations of God, who is also known by such names as the One, the Monad, Aion teleos (αἰών τέλεος "The Broadest Aeon"), Bythos ("depth or profundity", Greek βυθός), Proarkhe ("before the beginning", Greek προαρχή), the Arkhe ("the beginning", Greek ἀρχή), are called Aeons. In the different systems these emanations are differently named, classified, and described, but the emanation theory itself is common to all forms of Gnosticism. In the Basilidian Gnosis they are called sonships (υἱότητες huiotetes; sing.: υἱότης huiotes); according to Marcus, they are numbers and sounds; in Valentinianism they form male/female pairs called syzygies (Greek συζυγίαι, from σύζυγοι syzygoi, lit. "yokings together").
