Plutarch, De Iside et Osiride
Goodwin, Ed.

And that which the present priests do darkly hint out and insinuate to us, though with much obscurity, great shyness, and precaution,—that this God is the governor and prince of those that are dead, and that he is no other than he who is called by the Greeks Hades and Pluto,— being not taken in its true sense, disturbs the minds of the greater part, while they suspect that the truly holy and good God Osiris lives within and beneath the earth, where the bodies of those who are supposed to have an end lie hid and buried. But he himself is at the remotest distance from the earth imaginable, being unstained and unpolluted, [p. 136] and clean from every substance that is liable to corruption and death. But men's souls encompassed here with bodies and passions, have no communication with God, except what they can reach to in conception only, by means of philosophy, as by a kind of an obscure dream. But when they are loosed from the body, and removed into the unseen, invisible, impassible, and pure region, this God is then their leader and king; they there as it were hanging on him wholly, and beholding without weariness and passionately affecting that beauty which cannot be expressed or uttered by men. This the Goddess Isis is always caressing, affecting, and enjoying, according to the old tales, and by that means she fills this lower world with all those goodly and excellent things which partake of generation.
