Plutarch De Iside et Osiride 36

[36] Not only the Nile, but every form of moisture ¹ they call simply the effusion of Osiris; and in their holy rites the water jar in honour of the god heads the procession. ² And by the picture of a rush they represent a king and the southern region of the world, ³ and the rush is interpreted to mean the watering and fructifying of all things, and in its nature it seems to bear some resemblance to the generative member. Moreover, when they celebrate the festival of the Pamylia which, as has been said, ⁴ is of a phallic nature, they expose and carry about a statue of which the male member is triple ⁵ ; for the god is the Source, and every source, by its fecundity, multiplies what proceeds from it; and for many times we have a habit of saying thrice, as, for example, thrice happy, ⁶ and unless, indeed, the word triple is used by the early writers in its strict meaning; for the nature of moisture, being the source and origin of all things, created out of itself three primal material substances, Earth, Air, and Fire. In fact, the tale that is annexed to the legend to the effect that Typhon cast the male member of Osiris into the river, and Isis could not find it, but constructed and shaped a replica of it, and ordained that it should be honoured and borne in processions, ⁸ plainly comes round to this doctrine, that the creative and germinal power of the god, at the very first, acquired moisture as its substance, and through moisture combined with whatever was by nature capable of participating in generation.

There is another tale current among the Egyptians, that Apopis, brother of the Sun, made Avar upon Zeus, and that because Osiris espoused Zeus’s cause and helped him to overthrow his enemy, Zeus adopted Osiris as his son and gave him the name of Dionysus. It may be demonstrated that the legend contained in this tale has some approximation to truth so far as Nature is concerned; for the Egyptians apply the name Zeus to the wind, ⁹ and whatever is dry or fiery is antagonistic to this. This is not the Sun, but it has some kinship with the Sun; and the moisture, by doing away with the excess of dryness, increases and strengthens the exhalations by which the wind is fostered and made vigorous.

[36] And they call not only the Nile, but in general every humid, the efflux of Osiris. And a pitcher of water goes always first in their sacred processions, in honor of the God. And they make the figure of a fig-leaf both for the king and the southern climate, which fig-leaf is interpreted to mean the watering and fructifying of the universe, for it seems to bear some resemblance in its make to the virilities of a man. Moreover, when they keep the feast of the Pamylia, which is a Phallic or Priapeian one (as was said before), they expose to view and carry about a certain image of a man with a threefold privity; for this God is a first origin, and every first origin doth by its fecundity multiply what proceeds from it. And we are commonly used instead of many times to say thrice, as thrice happy, and, Unless (by Jove) we are to understand the word treble as spoken by the ancients in a proper sense. For the humid nature, being in the beginning the chief source and origin of the universe, must of consequence produce the three first bodies, — the earth, air, and fire. For the story which is here told by way of surplusage to the tale — how that Typhon threw the privity of Osiris into the river, and that Isis could not find it, and therefore fashioned and prepared the resemblance and effigies of it, and appointed it to be worshipped and carried about in their processions, like as in the Grecian Phallephoria — amounts but to this, to instruct and teach us that the prolific and generative property of this God had moisture for its first matter, and that by means of moisture it came to immix itself with things capable of generation. We have also another story told us by the Egyptians, — how that once Apopis, brother to the Sun, fell at variance with Jupiter and made war upon him; but Jupiter, entering into an alliance with Osiris and by his means overthrowing his enemy in a pitched battle, afterwards adopted him for his son and gave him the name of Dionysus. It is easy to show that this fabular relation borders also upon the verity of physical science. For the Egyptians call the wind Jupiter, with which the parching and fiery property makes war; and though this be not the sun, yet hath it some cognation with the sun. But now moisture, extinguishing the excessiveness of drought, increases and strengthens the exhalations of wet, which give food and vigor to the air.
