Michael Psellus on the Operation of Daemons

But the demoniacal Euchitæ have adopted yet a third origin; according to them, two sons, with their father, make the senior and the junior origin. To the father, they have assigned the supra-mundane region solely; to the younger son, the atmospheric region; and to the elder, the government of things in the world—a theory which differs in nothing from the Greek mythology, according to which the universe is portioned out into three parts. These rotten-minded men, having laid this rotten foundation, thus far are unanimous in their sentiments; but from this point, they are divided in their judgments into three parties. Some yield worship to both sons, maintaining that though they are at variance, both are equally deserving of being worshipped because they are sprung from one parent and will yet be reconciled. Others serve the younger son as being the governor of the superior region, which extends immediately over the earth; and yet they do not absolutely disdain the elder son, but are on their guard against him, as one who has it in his power to do them injury. While the third party, who are further sunk in impiety, withdraw altogether from the worship of the celestial son and enshrine in their hearts the earthly alone, even Satan, dignifying him with the most august names—such as the First-begotten, Estranged from the Father, the Creator of Plants and Animals, and the rest of the compound beings. Preferring to make suit to him who is the Destroyer and Murderer, gracious God! how many insults do they offer to the Celestial, whom they pronounce envious, an unnatural persecutor of his brother (who administers the government of the world), and aver that it is his being puffed up with envy that occasions earthquakes, hail, and famine, on which account they imprecate on him, as well as other anathemas, that horrible one! * * * *
