In Sethian Gnosticism, a luminary is an angel-like being (or heavenly dwelling place in the Apocryphon of John).
Four luminaries are typically listed in Sethian Gnostic texts, such as the Secret Book of John, the Holy Book of the Great Invisible Spirit, and Zostrianos.
The luminaries are considered to be emanations of the supreme divine triad consisting of the Father (Invisible Spirit), the Mother (Barbelo), and the Child (Autogenes).
Eleleth appears in Hypostasis of the Archons, Apocryphon of John, and The Three Forms of the First Thought found in the Nag Hammadi library in 1945 and is probably mentioned in the Gospel of Judas as El.
After Eleleth appeared, the Archons withdraw from Norea, and Eleleth informs Norea about her true origin and the origin of the world.
