world full of pain and suffering that he created. However, not all Gnostic movements regarded the creator of the material universe as inherently evil or malevolent. For instance, Valentinians believed that the Demiurge is merely an ignorant and incompetent creator, trying to fashion the world as well as he can, but lacking the proper power to maintain its goodness. They were regarded as heretics by the proto-orthodox Early Church Fathers. Yaldabaoth is primarily mentioned in the Archontic, Sethian, and Ophite writings of Gnostic literature, most of which have been discovered in the Nag Hammadi library. In the Apocryphon of John, "Yaldabaoth" is the first of three names of the domineering archon, along with Saklas and Samael. In Pistis Sophia he has lost his claim to rulership and, in the depths of Chaos, together with 49 demons, tortures sacrilegious souls in a scorching hot torrent of pitch. Here he is a lion-faced archon, half flame, half darkness. Yaldabaoth appears as a rebellious angel both in the apocryphal Gospel of Judas and the Gnostic work Hypostasis of the Archons. In some of these Gnostic texts, Yaldabaoth is further identified with the Ancient Roman god Saturnus. Cosmogony and creation myths Yaldabaoth is the son of Sophia, the personification of wisdom in Gnosticism, with whom he contends. By creatively turning to matter in goodness and simplicity, Sophia created the imperfect Yaldabaoth, who has no knowledge of the other aeons. From his mother he received the powers of light, but he used them for evil. Sophia rules over the Ogdoas, the Demiurge over the Hebdomas. Yaldabaoth created six more archons and other fellows. The angels he created rebelled against Yaldabaoth. To keep the angels in subjection, Yaldabaoth generated the material universe. In the act of creation, however, Yaldabaoth emptied himself of his supreme power. When Yaldabaoth breathed the soul into the first man, Adam, Sophia instilled in him the divine spark of the spirit. After matter, Yaldabaoth produced the serpent spirit (Ophiomorphos), which is the origin of all evil. The light being Sophia caused the fall of man through the serpent. By eating the forbidden fruit, Adam and Eve became enlightened and turned away from Yaldabaoth. Eventually, Yaldabaoth expelled them from the ethereal region, the Paradise, as punishment. Yaldabaoth continuously attempted to deprive human beings of the gift of the spark of light which he had unwittingly lost to them, or to keep them in
