5 They have also given names to [the several persons] in their system of falsehood, such as the following: he who was the first descendant of the mother is called Ialdabaoth; he, again, descended from him, is named Iao; he, from this one, is called Sabaoth; the fourth is named Adoneus; the fifth, Eloeus; the sixth, Oreus; and the seventh and last of all, Astanphæus. Moreover, they represent these heavens, potentates, powers, angels, and creators, as sitting in their proper order in heaven, according to their generation, and as invisibly ruling over things celestial and terrestrial.
The first of them, namely Ialdabaoth, holds his mother in contempt, inasmuch as he produced sons and grandsons without the permission of any one, yea, even angels, archangels, powers, potentates, and dominions. After these things had been done, his sons turned to strive and quarrel with him about the supreme power—conduct which deeply grieved Ialdabaoth, and drove him to despair. In these circumstances, he cast his eyes upon the subjacent dregs of matter, and fixed his desire upon it, to which they declare his son owes his origin.
This son is Nous himself, twisted into the form of a serpent; and hence were derived the spirit, the soul, and all mundane things: from this too were generated all oblivion, wickedness, emulation, envy, and death. They declare that the father imparted still greater crookedness to this serpent-like and contorted Nous of theirs, when he was with their father in heaven and Paradise.
