Gnosticism
Monad

In many Gnostic systems, God is known as the Monad, the One. God is the high source of the pleroma, the region of light. The various emanations of God are called æons. According to Hippolytus, this view was inspired by the Pythagoreans, who called the first thing that came into existence the Monad, which begat the dyad, which begat the numbers, which begat the point, begetting lines, etc.
