“Since there are in the universe, things which subsist differently at different times, and since there are also natures which are conjoined with the superessential unities, it is necessary that there should be a certain middle genus, which is neither immediately suspended from deity, nor subsists differently at different times according to better and worse, but which is always perfect, and does not depart from its proper virtue; and is immutable indeed but is not conjoined with the superessential. The whole of this genus is dæmoniacal. There are also different genera of dæmons; for they are arranged under the mundane Gods. The highest of these subsists according to _the one_ of the Gods, which is called an unific and divine genus of dæmons. The next according to the intellect which is suspended from Deity, and is called intellectual. The third subsists according to soul, and is called rational. The fourth according to nature, and is denominated physical. The fifth according to body, and is called corporeal-formed. And the sixth according to matter, and this is denominated material. Or after another manner it may be said, that some of these are celestial, others ethereal, others aerial, others aquatic, others terrestrial, and others subterranean. With respect also to this division, it is evident that it is derived from the parts of the universe. But irrational dæmons originate from the serial governors, whence also the [Chaldean] Oracle says, ηεριων ελατηρα κυνων χθονιων τε και υγρων. i.e. “being the charioteer of the aerial, terrestrial and aquatic dogs.” Our guardian dæmons, however, belong to that order of dæmons, which is arranged under the Gods that preside over the ascent and descent of souls.” Olympiodorus further observes, “that the dæmon endeavours to lead the soul as exciting its conceptions and imaginations, at the same time, however, yielding to the self-motive power of the soul. But in consequence of the dæmon exciting, one soul follows voluntarily, another violently, and another according to a mode subsisting between these. There is also one dæmon who leads the soul to its judges from the present life; another who is ministrant to the judges, giving completion, as it were, to the sentence which is passed; and a third who is allotted the guardianship of life.”
