How they who were men obtained the name of gods
Marcus Tullius, who was not only an accomplished orator, but also a philosopher, since he alone was an imitator of Plato, in that treatise in which he consoled himself concerning the death of his daughter, did not hesitate to say that those gods who were publicly worshipped were men. And this testimony of his ought to be esteemed the more weighty, because he held the priesthood of the augurs, and testifies that he worships and venerates the same gods. And thus within the compass of a few verses he has presented us with two facts.
For while he declared his intention of consecrating the image of his daughter in the same manner in which they were consecrated by the ancients, he both taught that they were dead, and showed the origin of a vain superstition. “Since, in truth,” he says, “we see many men and women among the number of the gods, and venerate their shrines, held in the greatest honour in cities and in the country, let us assent to the wisdom of those to whose talents and inventions we owe it that life is altogether adorned with laws and institutions, and established on a firm basis.
And if any living being was worthy of being consecrated, assuredly it was this. If the offspring of Cadmus, or Amphitryon, or Tyndarus, was worthy of being extolled by fame to the heaven, the same honour ought undoubtedly to be appropriated to her. And this indeed I will do; and with the approbation of the gods, I will place you the best and most learned of all women in their assembly, and will consecrate you to the estimation of all men.” Some one may perhaps say that Cicero raved through excessive grief.
But, in truth, the whole of that speech, which was perfect both in learning and in its examples, and in the very style of expression, gave no indications of a distempered mind, but of constancy and judgment; and this very sentence exhibits no sign of grief. For I do not think that he could have written with such variety, and copiousness, and ornament, had not his grief been mitigated by reason itself, and the consolation of his friends and length of time. Why should I mention what he says in his books concerning the Republic, and also concerning glory?
For in his treatise on the Laws, in which work, following the example of Plato, he wished to set forth those laws which he thought that a just and wise state would employ, he thus decreed concerning religion: “Let them reverence the gods, both those who have always been regarded as gods of heaven, and those whose services to men have placed them in heaven: Hercules, Liber, Æsculapius, Castor, Pollux, and Quirinus.” Also in his Tusculan Disputations, when he said that heaven was almost entirely filled with the human race, he said: “If, indeed, I should attempt to investigate ancient accounts, and to extract from them those things which the writers of Greece have handed down, even those who are held in the highest rank as gods will be found to have gone from us into heaven.
Inquire whose sepulchres are pointed out in Greece: remember, since you are initiated, what things are handed down in the mysteries; and then at length you will understand how widely this persuasion is spread.” He appealed, as it is plain, to the conscience of Atticus, that it might be understood from the very mysteries that all those who are worshipped were men; and when he acknowledged this without hesitation in the case of Hercules, Liber, Æsculapius, Castor and Pollux, he was afraid openly to make the same admission respecting Apollo and Jupiter their fathers, and likewise respecting Neptune, Vulcan, Mars, and Mercury, whom he termed the greater gods; and therefore he says that this opinion is widely spread, that we may understand the same concerning Jupiter and the other more ancient gods: for if the ancients consecrated their memory in the same manner in which he says that he will consecrate the image and the name of his daughter, those who mourn may be pardoned, but those who believe it cannot be pardoned.
For who is so infatuated as to believe that heaven is opened to the dead at the consent and pleasure of a senseless multitude? Or that any one is able to give to another that which he himself does not possess? Among the Romans, Julius was made a god, because it pleased a guilty man, Antony; Quirinus was made a god, because it seemed good to the shepherds, though one of them was the murderer of his twin brother, the other the destroyer of his country. But if Antony had not been consul, in return for his services towards the state Caius Cæsar would have been without the honour even of a dead man, and that, too, by the advice of his father-in-law Piso, and of his relative Lucius Cæsar, who opposed the celebration of the funeral, and by the advice of Dolabella the consul, who overthrew the column in the forum, that is, his monuments, and purified the forum.
For Ennius declares that Romulus was regretted by his people, since he represents the people as thus speaking, through grief for their lost king: “O Romulus, Romulus, say what a guardian of your country the gods produced you? You brought us forth within the regions of light. O father, O sire, O race, descended from the gods.” On account of this regret they more readily believed Julius Proculus uttering falsehoods, who was suborned by the fathers to announce to the populace that he had seen the king in a form more majestic than that of a man; and that he had given command to the people that a temple should be built to his honour, that he was a god, and was called by the name of Quirinus.
By which deed he at once persuaded the people that Romulus had gone to the gods, and freed the senate from the suspicion of having slain the king.
