A lion-faced deity found on a Gnostic gem in Bernard de Montfaucon's L'antiquité expliquée et représentée en figures may be a depiction of the Demiurge.Like Plato, Gnosticism also presents a distinction between the highest, unknowable "alien God" and the demiurgic "creator" of the material. However, in contrast to Plato, several systems of Gnostic thought present the Demiurge as antagonistic to the will of the Supreme Creator: his act of creation occurs in unconscious imitation of the divine model, and thus is fundamentally flawed, or else is formed with the malevolent intention of entrapping aspects of the divine in materiality. Thus, in such systems, the Demiurge acts as a solution to the problem of evil. In the Apocryphon of John circa 200AD (several versions of which are found in the Nag Hammadi library), the Demiurge has the name "Yaltabaoth", and proclaims himself as God:
"Now the archon who is weak has three names. The first name is Yaltabaoth, the second is Saklas, 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."
"Yaldabaoth" literally means "Child, come here" in a Semitic language. For example, the Hebrew word for "child" is "yeled", and for "go" is "bo". Thus, most probably "yalda" and "baoth" are declensions of "child" and "go", together meaning "child, come hither" (the language's identification as Hebrew itself is doubtful).
Gnostic myth recounts that Sophia (Greek, literally meaning "wisdom"), the Demiurge's mother and a partial aspect of the divine Pleroma or "Fullness", desired to create something apart from the divine totality, and without the receipt of divine assent. In this abortive act of separate creation, she gave birth to the monstrous Demiurge and, being ashamed of her deed, she wrapped him in a cloud and created a throne for him within it. The Demiurge, isolated, did not behold his mother, nor anyone else, and thus concluded that only he himself existed, being ignorant of the superior levels of reality that were his birth-place.
The Gnostic myths describing these events are full of intricate nuances portraying the declination of aspects of the divine into human form; this process occurs through the agency of the Demiurge who, having stolen a portion of power from his mother, sets about a work of creation in unconscious imitation of the superior Pleromatic realm. Thus Sophia's power becomes enclosed within the material forms of humanity, themselves entrapped within the material universe: the goal of Gnostic movements was typically the awakening of this spark, which permitted a return by the subject to the superior, non-material realities which were its primal source. (See Sethian Gnosticism.)
"Samael" may equate to the Judaic Angel of Death, and corresponds to the Christian demon of that name, as well as Satan. Literally, it can mean "Blind God" or "God of the Blind" in Aramaic (Syriac sæmʕa-ʔel). Another alternative title for Yaldabaoth, "Saklas", is Aramaic for "fool" (Syriac sækla "the foolish one").
Some Gnostic philosophers (notably Marcion of Sinope) identify the Demiurge with Yahweh, the God of the Old Testament, in opposition and contrast to the God of the New Testament. Still others equated the being with Satan. Catharism apparently inherited their idea of Satan as the creator of the evil world directly or indirectly from Gnosticism. Or, they may well have gotten the idea directly from the New Testament, which refers to Satan as "The God <'ho theos'> of this age" in Second Corinthians 4:4. Also, the NT asserts that the "whole world lies in the power of the evil one" in 1 John 5:19. Though nowhere in the New Testament is the creator of the world or the universe identified as Satan, although Yahweh declares in Isaiah 45:7 that He "makes good and creates evil
. Nor in the old or New Testament is nature or earth created by the creator referred to as evil, unlike the so-called Gnostic "sectarians." (Unless one sees the attribute of Creatorship as inherent in the concept of "God," and therefore the title "The God of this Age" applied to Satan becomes a powerful indicator that Satan is indeed the creator. Other modern-day Cathars see a further indication of this in the epithet "Kosmokrator" which is applied to Satan in Ephesian 6:12, as a further indication of the creatorship of Satan and his identity with the Demiurge)
