Cosmocrator

Cosmocrator — in Valentinian gnosticism, Cosmocrator is ruler of the material cosmos in the guise of Diabolos (the devil). His consort is Barbelo and together "they sing praises to the Powers of the Light," which would indicate that Cosmocrator is not wholly evil.

In the same vein, according to the Jewish lists of ten cosmocrators the tenth and last king will be God himself.

It is the confluence of Old Testament and Hellenistic terminology that makes him more than a mere cultic hero or lord; he is cosmocrator, lord of the cosmos, for the powers in v. 10 are cosmic powers.

Pursuing the same project with the same ontological purpose, Proclus will later admit the seven cosmocrators as the seven planets into his Neoplatonist scheme. "The planets are called 'cosmocrators'" but they are no longer rebellious aeons fragmenting the pleroma through their ignorance.

In addition to the Demiurge, they also speak of a Cosmocrator (ruler of the world) and of evil spirits.
