8 Ialdabaoth, however, through that oblivion in which he was involved, and not paying any regard to these things, cast Adam and Eve out of Paradise, because they had transgressed his commandment. For he had a desire to beget sons by Eve, but did not accomplish his wish, because his mother opposed him in every point, and secretly emptied Adam and Eve of the light with which they had been sprinkled, in order that that spirit which proceeded from the supreme power might participate neither in the curse nor opprobrium [caused by transgression]. They also teach that, thus being emptied of the divine substance, they were cursed by him, and cast down from heaven to this world. But the serpent also, who was acting against the father, was cast down by him into this lower world; he reduced, however, under his power the angels here, and begot six sons, he himself forming the seventh person, after the example of that Hebdomad which surrounds the father. They further declare that these are the seven mundane demons, who always oppose and resist the human race, because it was on their account that their father was cast down to this lower world.
