Plutarch, De Iside et Osiride 23

ὀκνῶ δέ, μὴ τοῦτʼ ᾖ τὰ ἀκίνητα κινεῖν καὶ πολεμεῖν οὐ τῷ πολλῷ χρόνῳ (κατὰ Σιμωνίδην) μόνον, πολλοῖς δʼ ἀνθρώπων ἔθνεσι καὶ γένεσι κατόχοις ὑπὸ τῆς πρὸς τοὺς θεοὺς τούτους ὁσιότητος, οὐδὲν ἀπολιπόντας ἐξ οὐρανοῦ μεταφέρειν ἐπὶ γῆν ὀνόματα τηλικαῦτα, καὶ τιμὴν καὶ πίστιν ὀλίγου δεῖν ἅπασιν ἐκ πρώτης γενέσεως ἐνδεδυκυῖαν ἐξιστάναι καὶ ἀναλύειν, μεγάλας μὲν τῷ ἀθέῳ λεῲ κλισιάδας ἀνοίγοντας καὶ ἐξανθρωπίζοντας τὰ θεῖα, λαμπρὰν δὲ τοῖς Εὐημέρου τοῦ Μεσσηνίου φενακισμοῖς παρρησίαν διδόντας, ὃς αὐτὸς ἀντίγραφα συνθεὶς ἀπίστου καὶ ἀνυπάρκτου μυθολογίας πᾶσαν ἀθεότητα κατασκεδάννυσι τῆς οἰκουμένης, τοὺς νομιζομένους θεοὺς πάντας ὁμαλῶς διαγράφων εἰς ὀνόματα στρατηγῶν καὶ ναυάρχων καὶ βασιλέων ὡς δὴ πάλαι γεγονότων, ἐν δὲ Πάγχοντι γράμμασι χρυσοῖς ἀναγεγραμμένων, οἷς οὔτε βάρβαρος οὐδεὶς οὔθʼ Ἕλλην, ἀλλὰ μόνος Εὐήμερος, ὡς ἔοικε, πλεύσας εἰς τοὺς μηδαμόθι γῆς γεγονότας μηδʼ ὄντας Παγχώους καὶ Τριφύλλους ἐντετυχήκει.

I hesitate, lest this be the moving of things immovable and not only warring against the long years of time, as Simonides has it, but warring, too, against many a nation and race of men who are possessed by a feeling of piety towards these gods, and thus we should not stop short of transplanting such names from the heavens to the earth, and eliminating and dissipating the reverence and faith implanted in nearly all mankind at birth, opening wide the great doors to the godless throng, degrading things divine to the human level, and giving a splendid licence to the deceitful utterances of Euhemerus of Messene,who of himself drew up copies of an incredible and non-existent mythology, and spread atheism over the whole inhabited earth by obliterating the gods of our belief and converting them all alike into names of generals, admirals, and kings, who, forsooth, lived in very ancient times and are recorded in inscriptions written in golden letters at Panchon, which no foreigner and no Greek had ever happened to meet with, save only Euhemerus. He, it seems, made a voyage to the Panchoans and Triphyllians, who never existed anywhere on earth and do not exist!
