When we see how carefully these oracles were guarded and how circumspectly their use was hedged about by senatorial control, and when we think how relatively little harm the use of oracles had wrought in Greece in all the centuries of her history, it may well seem as if the statements made in the beginning of this chapter about the havoc caused by these oracles were grossly exaggerated. But the efforts of the Senate to safeguard these oracles only prove that the older and wiser men in the community realised how dangerous they were, and the comparison with Greece leads to a consideration of certain essential differences between the Greek and the Roman temperament which made that which was meat for one into poison for the other.

In the older purer age of Greece the gods were never far away from men, they lived almost side by side with them; there were to be sure many gods of whom they were afraid and from whom they desired to keep as far away as possible, but there were a great many other gods of whom they liked to think. In constructing the records of their history they did not work backwards from the light of the present into an ever darkening past, but they began from the beginning in the full light of the gods from whom all things sprang, and mythology passed into history by imperceptible gradations. They knew more about the beginning when all things were completely in the hands of the gods than they did about their immediate past. Art began very early to make them familiar with the appearance of the gods, so that there was little that was mysterious about their religion, so little that the element of mystery had later to be almost artificially cultivated in the "mysteries." They respected the gods rather than feared them, and they felt that the gods would do them no harm unless they themselves first sinned against them or their own fellow-men, and the oracles of Delphi were no more terrifying to them than the coming of the word of God was to the prophets of Israel. They were accustomed to these messages, which were almost every-day affairs. It was all a part of that marvellous poise of nature which made the every-day mortal Greek almost as calm as the unperturbed imperturbable faces of their gods as their great sculptors saw them.

In Rome all was very different. The superstitious element in the Italian character, which amazes us so much to-day when cultured twentieth century men and women in good society persecute their fellows because of the evil eye, is a heritage of many thousand years. Sometimes it seems as if it were the Italian birthright, the blight of Etruria which came into their nature in spite of themselves. It required centuries to educate the Roman into the concept of personal individual gods. He had begun his theological career by terror of unknown powers all about him, and by regarding religion as the science of propitiating the right power on the right occasion. One could not know these powers, one did not desire to. Their gods were at once their masters and their servants, but never their companions. The early Roman knew no such thing as an oracle, the only messages from the gods were the expressions of their wrath, in the sending of prodigies and portents. They did indeed consult the gods by watching the flight of birds or studying the entrails of the sacrifice, but it was merely to obtain a "yes or no" answer to a categorical question as to whether a certain act was pleasing to the gods. Otherwise all about them lay mystery, and at the point where sight failed, since neither imagination nor faith carried them any further, superstition stepped in, and the more they thought of the gods the more terrified they became. Now if you present to a people thus constituted a divine book of infallible oracles, you increase their terror in greater measure than the book itself can assuage it, and with the use of the book the simpler forms of their old belief will grow less and less effective in the face of this new "witchcraft," which can work wonders. And no matter how you may hedge the use of the book about, it will be used more and more as the craving for magic is increasingly aroused.

The study of the outward and the inward effects of the Sibylline books is therefore the real history of religion in the first half of the republic. The outward effects are seen in the introduction of a series of Greek gods, who were in themselves in the main eminently respectable, and whose presence was in itself no offence to good morals, and if we stop there we fail to understand why the religious interest of the Second Punic War should change so quickly to the scepticism of the following century. The inward effects however, which, though they are hard to see, may yet be discovered between the lines of the chronicle, will explain all the undermining of foundation, until we wonder not why the structure collapsed so suddenly but how it managed to last so long.

The history of the activity of the books begins peaceably enough. In the year B.C. 496 Rome was in a bad way; her crops had failed and the importation of grain from Latium was rendered very difficult because of the war with the Latins in which she was engaged. In her distress she turned to the Sibylline books, and on the occasion of this their first recorded use, the oracles ordered the introduction into Rome of the cult of three Greek deities, Demeter, Dionysos, and Kore. It was a most appropriate and characteristic choice. In the first place the deities in question were worshipped at Cumae, the home of the books, whence Rome could, and probably did, borrow the cult; and in the second place Demeter was the goddess of grain, and it was from Cumae that Rome was already beginning to obtain her imported grain supply. Thus the coming of the Cumaean Demeter into the religious world of Rome is but the sacred parallel to the coming of Cumaean grain into the material world of Rome. The Greek goddess of grain came with the grain, just as Castor had come with the Greek cavalry, with this essential distinction however that Demeter came by the incantation of the books and the enactment of the Senate, whereas Castor's coming was a slow and normal development.

It is important to notice closely exactly what happened when these deities were introduced, partly because they form the first recorded instance, and hence may well have acted as a model for subsequent repetitions of the act, but also because we have a more definite knowledge of the phenomena in this case than in many others. In the first place it is clear that the deities were felt to be foreign: not only was their temple built out the Aventine way, in the valley of the Circus Maximus, outside the pomerium, but—a much more significant fact—their Greek names were dropped, and they were given Roman names instead, to make them seem less out of place. Then too these Roman names were not new names, translations of their Greek titles, but were the names of already existing Roman deities with whom they were easily identified, so that we see at once that their coming was no real enrichment of the Roman Olympus; what they stood for was already represented there, and their coming was simply a reduplication, with the consequent result that as these parvenus increased in prominence and influence, they robbed of all their vitality the sober old Roman deities to whom they had attached themselves. What were these original deities who were thus doomed to death in B.C. 496? Demeter took the name of the old Roman goddess Ceres, a goddess of fertility, about whom we know just enough to assert that she belonged to the old religion of Numa and that she was at heart quite a different person from Demeter. All the rest is lost, submerged under the new Demeter-Ceres with her temple built by Greek architects and her April games. It is this new Ceres who soon develops an extraordinary political importance because her temple is to the Plebeians as a class what the temple of Minerva is to the unions of organised labour. It is there that they have their meeting-place, and the temple itself is always their treasury as contrasted with the Saturn temple, the treasury of the state as a whole. The very officers of the Plebeians, the famous Plebeian aediles, get their name from association with this temple (aedes). This political side of her activity is the only real advantage, except the grain itself, connected with her importation; the two form at best a poor economic compensation for the ever increasing immoral effects of the public games of Ceres.

But though Ceres is the most important of the three deities economically and politically, we must not forget the other two, both of whom are interesting, though one of them more for what she is not than for what she is. Along with Demeter came Dionysos and Demeter's daughter Kore: the three were associated in the solemn mysteries of Eleusis, but none of the beauty of these ideas went over into the Roman cult. Demeter was merely the deified grain-traffic, and Dionysos was little else than the god of wine, while poor Kore fell out without any particular content for a curious reason that we shall see in a moment. The only old Roman deity with whom Dionysos could be identified was the god Liber, who had had a rather interesting history, and who had done enough along the line of self-development to deserve a better fate than to be crushed to insignificance under the prominence of his new namesake. Liber was at this time a flourishing god of fertility and, since the introduction of the grape into Italy, especially the patron of the fruit of the vine, but he had made his own career, and there was a time when he had no individuality of his own but was merely a cult-adjective of the great god Juppiter, the giver of all fertility in every phase of life. Thus out of the original Juppiter-Liber there had grown the independent god Liber; and now this Liber lost his individuality by identification with Dionysos. Finally comes Kore, Demeter's daughter. Here the Romans were hard put to it to find a goddess who represented any similar content, and after all this was no light task because Kore has little meaning unless she is taken also as Persephone, Pluto's bride—a process which required a mythological knowledge and appreciation in which the Romans of the early republic were totally lacking. But there was an old goddess Libera, a shadowy potentiality contrasted and paired with the masculine Liber, and they chose her and gave Kore her name. We have a curious proof of how little the Romans knew of Kore-Libera, and of how purely mechanical both the introduction of Kore and her identification with Libera were, in the fact that about two hundred and fifty years later, as we shall see, Persephone, the real Kore, was introduced into Rome as an altogether new deity, and existed there side by side with Libera for at least a century before people began to realise that Proserpina and Libera stood for the same Greek goddess.

It was necessary to go into these details in order that we might understand as much as possible of the process by which the gods of the Sibylline books were assimilated into the body of Roman religion. We see how in the main they were superfluous and therefore unnecessary and even undesirable because by their presence they robbed old Roman deities of their existence, and how those elements in them which were least in accord with the old Roman spirit were most apt to develop, and how in general their adoption was a purely mechanical process, like any act in witchcraft, where the form is all important because the meaning cannot be understood, and how totally different therefore the estate of these gods was in Rome from what it had been in Greece, because in Rome they were introduced, stripped of all their mythology, worshipped only for their practical bearings, and compelled therefore to work for their living.

The importation of grain from Cumae meant more to Rome than the mere satisfaction of her physical needs; it meant much more than the addition of three deities to her state-cult, for the grain thus imported was carried from Cumae to Ostia by sea and so up the Tiber to Rome, and the whole matter therefore marks one of the important steps in Rome's interest in commerce generally but especially in ocean commerce. As yet she did not do the actual carrying herself, but she began to be interested in it, and the sea began to mean something to this inland town. This increased interest in trade in general and this inceptive interest in those who "go down to the sea in ships" have both of them left their reflexion in the religious life of the time; two new deities are introduced, both of them almost certainly by means of the Sibylline oracles, though some accidental blanks in our historical tradition have deprived us of details.

The chronicle of the year B.C. 495 tells us that there was a dispute in that year as to who should dedicate the temple of Mercury. This is Mercury's first appearance in our sources. The circumstances of the vowing of the temple have been omitted through some oversight, but in spite of this the connexion of his introduction with the Sibylline books is beyond all reasonable doubt, for the simple reason that the guardians of the oracles always looked after his cult in all subsequent time. Notwithstanding the suddenness of his appearance and the silence of the chronicle, his story is quite clear and his past history easy to restore, at least in outline.
