Yaldabaoth

In the Ophite and Sethian systems, which have many affinities with that last mentioned, the making of the world is ascribed to a company of seven archons, whose names are given, but their chief, “Yaldabaoth” (also known as "Yaltabaoth" or "Ialdabaoth") comes into still greater prominence.
In the Apocryphon of John circa 120-180 AD, the Demiurge arrogantly declares that he has made the world by himself:
Now the archon (ruler) who is weak has three names. The first name is Yaltabaoth, the second is Saklas (“fool”), and the third is Samael.
And he is impious in his arrogance which is in him. For he said, "I am God and there is no other God beside me," for he is ignorant of his strength, the place from which he had come.[24]
He is Demiurge and maker of man, but as a ray of light from above enters the body of man and gives him a soul, Yaldabaoth is filled with envy; he tries to limit man's knowledge by forbidding him the fruit of knowledge in paradise. The Demiurge, fearing lest Jesus, whom he had intended as his Messiah, should spread the knowledge of the Supreme God, had him crucified by the Romans. At the consummation of all things all light will return to the Pleroma. But Yaldabaoth, the Demiurge, with the material world, will be cast into the lower depths.
In Pistis Sophia Yaldabaoth has already sunk from his high estate and resides in Chaos, where, with his forty-nine demons, he tortures wicked souls in boiling rivers of pitch, and with other punishments (pp. 257, 382). He is an archon with the face of a lion, half flame and half darkness.
Yaldabaoth is frequently called "the Lion-faced", leontoeides, with the body of a serpent. We are told also,[25] that the Demiurge is of a fiery nature, the words of Moses being applied to him, “the Lord our God is a burning and consuming fire,” a text used also by Simon.[26]
Under the name of Nebro (rebel), Yaldabaoth is called an angel in the apocryphal Gospel of Judas. He is first mentioned in “The Cosmos, Chaos, and the Underworld” as one of the twelve angels to come “into being [to] rule over chaos and the [underworld]”. He comes from heaven, his “face flashed with fire and whose appearance was defiled with blood”. Nebro creates six angels in addition to the angel Saklas to be his assistants. These six in turn create another twelve angels “with each one receiving a portion in the heavens.”
