Plutarch, De Iside et Osiride 11

ὅταν οὖν ἃ μυθολογοῦσιν Αἰγύπτιοι περὶ τῶν θεῶν ἀκούσῃς, πλάνας καὶ διαμελισμοὺς καὶ πολλὰ τοιαῦτα παθήματα, δεῖ τῶν προειρημένων μνημονεύειν καὶ μηδὲν οἴεσθαι τούτων λέγεσθαι γεγονὸς οὕτω καὶ πεπραγμένον. οὐ γὰρ τὸν κύνα κυρίως Ἑρμῆν λέγουσιν, ἀλλὰ τοῦ ζῴου τὸ φυλακτικὸν καὶ τὸ ἄγρυπνον καὶ τὸ φιλόσοφον, γνώσει καὶ ἀγνοίᾳ τὸ φίλον καὶ τὸ ἐχθρὸν ὁρίζοντος, ᾗ φησιν ὁ Πλάτων, τῷ λογιωτάτῳ τῶν θεῶν συνοικειοῦσιν. οὐδὲ τὸν ἥλιον ἐκ λωτοῦ νομίζουσι βρέφος ἀνίσχειν νεογνόν, ἀλλʼ οὕτως ἀνατολὴν ἡλίου γράφουσι, τὴν ἐξ ὑγρῶν ἡλίου γιγνομένην ἄναψιν αἰνιττόμενοι. καὶ γὰρ τὸν ὠμότατον Περσῶν βασιλέα καὶ φοβερώτατον Ὦχον ἀποκτείναντα πολλούς, τέλος δὲ καὶ τὸν Ἆπιν ἀποσφάξαντα καὶ καταδειπνήσαντα μετὰ τῶν φίλων, ἐκάλεσαν μάχαιραν, καὶ καλοῦσι μέχρι νῦν οὕτως ἐν τῷ καταλόγῳ τῶν βασιλέων, οὐ κυρίως δήπου τὴν οὐσίαν αὐτοῦ σημαίνοντες, ἀλλὰ τοῦ τρόπου τὴν σκληρότητα καὶ κακίαν ὀργάνῳ φονικῷ παρεικάζοντες. οὕτω δὴ τὰ περὶ θεῶν ἀκούσασα καὶ δεχομένη παρὰ τῶν ἐξηγουμένων τὸν μῦθον ὁσίως καὶ φιλοσόφως, καὶ δρῶσα μὲν ἀεὶ καὶ διαφυλάττουσα τῶν ἱερῶν τὰ νενομισμένα, τοῦ δʼ ἀληθῆ δόξαν ἔχειν περὶ θεῶν μηδὲν οἰομένη μᾶλλον αὐτοῖς μήτε θύσειν μήτε ποιήσειν κεχαρισμένον, οὐδὲν ἔλαττον ἀποφεύξῃ κακὸν ἀθεότητος δεισιδαιμονίαν.

Therefore, Clea, whenever you hear the traditional tales which the Egyptians tell about the gods, their wanderings, dismemberments, and many experiences of this sort, you must remember what has been already said, and you must not think that any of these tales actually happened in the manner in which they are related. The facts are that they do not call the dog by the name Hermes as his proper name, but they bring into association with the most astute of their gods that animal’s watchfulness and wakefulness and wisdom, since he distinguishes between what is friendly and what is hostile by his knowledge of the one and his ignorance of the other, as Plato remarks. Nor, again, do they believe that the sun rises as a new-born babe from the lotus, but they portray the rising of the sun in this manner to indicate allegorically the enkindling of the sun from the waters. So also Ochus, the most cruel and terrible of the Persian kings, who put many to death and finally slaughtered the Apis and ate him for dinner in the company of his friends, the Egyptians called the Sword; and they call him by that name even to this day in their list of kings. But manifestly they do not mean to apply this name to his actual being; they but liken the stubbornness and wickedness in his character to an instrument of murder. If, then, you listen to the stories about the gods in this way, accepting them from those who interpret the story reverently and philosophically, and if you always perform and observe the established rites of worship, and believe that no sacrifice that you can offer, no deed that …
