"Of myths some are theological, some physical, some psychic, and again some material, and some mixed from these last two. The theological are those myths which use no bodily form but contemplate the very essence of the Gods: e.g., Kronos swallowing his children. Since god is intellectual, and all intellect returns into itself, this myth expresses in allegory the essence of god. Myths may be regarded physically when they express the activities of the Gods in the world: e.g., people before now have regarded Kronos as time, and calling the divisions of time his sons say that the sons are swallowed by the father. The psychic way is to regard the activities of the soul itself; the soul's acts of thought, though they pass on to other objects, nevertheless remain inside their begetters. The material and last is that which the Egyptians have mostly used, owing to their ignorance, believing material objects actually to be Gods, and so calling them: e.g., they call the earth Isis, moisture Osiris, heat Typhon, or again, water Kronos, the fruits of the earth Adonis, and wine Dionysus. To say that these objects are sacred to the Gods, like various herbs and stones and animals, is possible to sensible men, but to say that they are Gods is the notion of madmen — except, perhaps, in the sense in which both the orb of the sun and the ray which comes from the orb are colloquially called "the sun"."
