One of the so-called philosophers in the first ages of Christianity, who claimed a true philosophical interpretation of the Christian religion. Their system combined Oriental theology and Greek philosophy with the doctrines of Christianity. They held that all natures, intelligible, intellectual, and material, are derived from the Deity by successive emanations, which they called Eons.
