32 But was that Euhemerus also a poet, who declares both Jupiter himself, and his father Saturn, and Pluto and Neptune his brothers, to have been men, in terms so exceedingly plain that their worshippers ought all the more to render thanks to the poets, because their inventions have not been intended so much to disparage them as rather to dress them up? Albeit Cicero mentions that this same Euhemerus was translated into Latin by the poet Ennius. Or was Cicero himself a poet, who, in counselling the person with whom he debates in his Tusculan Disputations, addresses him as one possessing knowledge of things secret, in the following terms: “If, indeed, I were to attempt to search into antiquity, and produce from thence the subjects which the writers of Greece have given to the world, it would be found that even those deities who are reckoned gods of the higher orders have gone from us into heaven. Ask whose sepulchres are pointed out in Greece: call to mind, since you have been initiated, the things which are delivered in the mysteries: then, doubtless, you will comprehend how widely extended this belief is.” This author certainly makes ample acknowledgment of the doctrine that those gods of theirs were originally men. He does, indeed, benevolently surmise that they made their way into heaven. But he did not hesitate to say in public, that even the honour thus given them in general repute was conferred upon them by men, when he spoke of Romulus in these words: “By good will and repute we have raised to the immortal gods that Romulus who founded this city.” How should it be such a wonderful thing, therefore, to suppose that the more ancient men did with respect to Jupiter and Saturn and the others what the Romans have done with respect to Romulus, and what, in good truth, they have thought of doing even in these more recent times also in the case of Cæsar? And to these same Virgil has addressed the additional flattery of song, saying:
“Lo, the star of Cæsar, descendant of Dione, arose.”
— Eclogue, ix. ver. 47.
Let them see to it, then, that the truth of history do not turn out to exhibit to our view sepulchres erected for their false gods here upon the earth!and let them take heed lest the vanity of poetry, instead of fixing, may be but feigning stars for their deities there in heaven. For, in reality, that one is not the star of Jupiter, neither is this one the star of Saturn; but the simple fact is, that upon these stars, which were set from the foundation of the world, the names of those persons were imposed after their death by men who were minded to honour them as gods on their departure from this life. And with respect to these we may, indeed, ask how there should be such ill desert in chastity, or such good desert in voluptuousness, that Venus should have a star, and Minerva be denied one among those luminaries which revolve along with the sun and moon?
