Satanaël a being whom the Bogomiles (q.v.) of the 12th century regarded as the first-born son of the supreme God, who sat at the right hand of God, holding the second place after him. To each of the higher spirits they believed that God had committed a particular administration, while Satanael was placed over all his universal vicegerents; but, having apostatized, he persuaded his companions in apostasy to create a new heaven and a new earth, which should be an empire independent of the supreme God. He ruled in the world which he had created, bringing many thousands to ruin by his seductive wiles. But the good God resolved to rescue men from the dominion of Satanael and to deprive him of power. This was accomplished by the Logos, who became incarnate, or, rather, took an ethereal body, which resembled an earthly body only in its outward appearance. Satanael was deprived by Christ of his divine power, and obliged to give up the name of El and retain only that of Satan. This doctrine has a marked resemblance to that of the Euchites.
