“The Epinomis
develops the theory of daimones into a system: In heaven there live the fiery
stars, on earth the earthly, living beings; it may be postulated that each of
the other elements, water, air, and aither, should also form its own living
beings. Of a watery nature indeed are the demigods, the heroes who appear
ghostlike and unclear; to air and aither in turn belong daimones, who are
entirely invisible. They nevertheless have a powerful mind; they know all our
thoughts, they delight in the good and hate the evil… The daimones can
correspondingly intervene; it is advisable to honour them with prayers.” – p. 332, Greek Religion, Walter Burkert.
