Of certain deities peculiar to barbarians, and their sacred rites; and in like manner concerning the Romans
We have spoken of the gods themselves who are worshipped; we must now speak a few words respecting their sacrifices and mysteries. Among the people of Cyprus, Teucer sacrificed a human victim to Jupiter, and handed down to posterity that sacrifice which was lately abolished by Hadrian when he was emperor. There was a law among the people of Tauris, a fierce and inhuman nation, by which it was ordered that strangers should be sacrificed to Diana; and this sacrifice was practised through many ages. The Gauls used to appease Hesus and Teutas with human blood. Nor, indeed, were the Latins free from this cruelty, since Jupiter Latialis is even now worshipped with the offering of human blood. What benefit do they who offer such sacrifices implore from the gods? Or what are such deities able to bestow on the men by whose punishments they are propitiated? But this is not so much a matter of surprise with respect to barbarians, whose religion agrees with their character. But are not our countrymen, who have always claimed for themselves the glory of gentleness and civilization, found to be more inhuman by these sacrilegious rites? For these ought rather to be esteemed impious, who, though they are embellished with the pursuits of liberal training, turn aside from such refinement, than those who, being ignorant and inexperienced, glide into evil practices from their ignorance of those which are good. And yet it is plain that this rite of immolating human victims is ancient, since Saturn was honoured in Latium with the same kind of sacrifice; not indeed that a man was slain at the altar, but that he was thrown from the Milvian bridge into the Tiber. And Varro relates that this was done in accordance with an oracle; of which oracle the last verse is to this effect: “And offer heads to Ades, and to the father a man.” And because this appears ambiguous, both a torch and a man are accustomed to be thrown to him. But it is said that sacrifices of this kind were put an end to by Hercules when he returned from Spain; the custom still continuing, that instead of real men, images made from rushes were cast forth, as Ovid informs us in his Fasti: “Until the Tirynthian came into these lands, gloomy sacrifices were annually offered in the Leucadian manner: he threw into the water Romans made of straw; do you, after the example of Hercules, cast in the images of human bodies.”
The Vestal virgins make these sacred offerings, as the same poet says: “Then also a virgin is accustomed to cast from the wooden bridge the images of ancient men made from rushes.”
For I cannot find language to speak of the infants who were immolated to the same Saturn, on account of his hatred of Jupiter. To think that men were so barbarous, so savage, that they gave the name of sacrifice to the slaughter of their own children, that is, to a deed foul, and to be held in detestation by the human race; since, without any regard to parental affection, they destroyed tender and innocent lives, at an age which is especially pleasing to parents, and surpassed in brutality the savageness of all beasts, which— savage as they are— still love their offspring! O incurable madness! What more could those gods do to them, if they were most angry, than they now do when propitious, when they defile their worshippers with parricide, visit them with bereavements, and deprive them of the sensibilities of men? What can be sacred to these men? Or what will they do in profane places, who commit the greatest crimes amidst the altars of the gods? Pescennius Festus relates in the books of his History by a Satire, that the Carthaginians were accustomed to immolate human victims to Saturn; and when they were conquered by Agathocles, the king of the Sicilians, they imagined that the god was angry with them; and therefore, that they might more diligently offer an expiation, they immolated two hundred sons of their nobles: “So great the ills to which religion could prompt, which has ofttimes produced wicked and impious deeds.” What advantage, then, did the men propose by that sacrifice, when they put to death so large a part of the state, as not even Agathocles had slain when victorious?
From this kind of sacrifices those public rites are to be judged signs of no less madness; some of which are in honour of the mother of the gods, in which men mutilate themselves; others are in honour of Virtus, whom they also call Bellona, in which the priests make offsprings not with the blood of another victim, but with their own. For, cutting their shoulders, and thrusting forth drawn swords in each hand, they run, they are beside themselves, they are frantic. Quintilian therefore says excellently in his Fanatic: “If a god compels this, he does it in anger.” Are even these things sacred? Is it not better to live like cattle, than to worship deities so impious, profane, and sanguinary? But we will discuss at the proper time the source from which these errors and deeds of such great disgrace originated. In the meantime, let us look also to other matters which are without guilt, that we may not seem to select the worse parts through the desire of finding fault. In Egypt there are sacred rites in honour of Isis, since she either lost or found her little son. For at first her priests, having made their bodies smooth, beat their breasts, and lament, as the goddess herself had done when her child was lost. Afterwards the boy is brought forward, as if found, and that mourning is changed into joy. Therefore Lucan says, “And Osiris never sufficiently sought for.” For they always lose, and they always find him. Therefore in the sacred rites there is a representation of a circumstance which really occurred; and which assuredly declares, if we have any intelligence, that she was a mortal woman, and almost desolate, had she not found one person. And this did not escape the notice of the poet himself; for he represents Pompey when a youth as thus speaking, on hearing the death of his father: “I will now draw forth the deity Isis from the tomb, and send her through the nations; and I will scatter through the people Osiris covered with wood.” This Osiris is the same whom the people call Serapis. For it is customary for the names of the dead who are deified to be changed, that no one, as I believe, may imagine them to be men. For Romulus after his death became Quirinus, and Leda became Nemesis, and Circe Marica; and Ino, when she had leapt into the sea, was called Leucothea; and the mother Matuta; and her son Melicerta was called Palæmon and Portumnus. And the sacred rites of the Eleusinian Ceres are not unlike these. For as in those which have been mentioned the boy Osiris is sought with the wailing of his mother, so in these Proserpine is carried away to contract an incestuous marriage with her uncle; and because Ceres is said to have sought for her in Sicily with torches lighted from the top of Etna, on this account her sacred rites are celebrated with the throwing of torches.
