[935]. Of a still different character is the figure of the Sibyl, created by the Greeks and adopted by the Romans.[1721] She, too, is possessed by a god and sometimes, at least, raves in ecstasy; but she does not officiate at a shrine and is not controlled by any official body. She dwells in a cave or a grotto, has her life in the open air, and gives her answers on the leaves of the forest. She represents the divine voices that are heard by early men everywhere in the world; in the myth, when she displeases Apollo she is condemned to fade finally, after a long life, into a voice.[1722] She is not, like the Pythia, an actual human being—she is never seen except in legends and myths. She is a creature of Greek imagination, the embodiment of all the divine suggestions that come to man from the mysterious sounds around him.
[936]. The historical origin of the fully developed figure of the Sibyl is obscure.[1723] In the literature she appears first in the sixth century B.C. along with the Pythia, but she was then thought of as well established and ancient. She is not mentioned by Homer or Hesiod, but their silence is not proof positive that the conception of the character did not exist in their time; they may have had no occasion to mention her, or the figure may have been so vague and unimportant as not to call for special mention. For such a figure it is natural to assume a long development, the beginnings of which are, of course, enveloped in obscurity. However this may be, the Sibyl appears to have received full form under the religious impulse of post-Homeric times, under conditions the details of which are not known to us.
[937]. In the scant notices of the figure that have been preserved the indications are that there was originally only one Sibyl—she was the mythical embodiment of divine revelation, as the muse was the embodiment of intellectual inspiration. At a later time many sibyls came into being; Varro reckons ten and other authors give other numbers. Apparently a process of local differentiation went on; when the idea of the revealer was once established and the historical beginnings of the figure were unknown, many a place would be ambitious to have so noble a figure domiciled in its midst. One line of tradition referred the original Sibyl to the Ionian Erythræ, and when the Sibylline Books were burned in the year 83 B.C., it was to Erythræ that the Romans sent to make a new collection of oracles. Whatever the original home of the figure, one of the most famous of the Sibyls was she of Cumæ.[1724] She was regarded as being very old, and she was probably a permanent diviner of that place. It was from Cumæ, according to the legend, that the Sibylline Books came to Rome. The story of how they were first offered to King Tarquinius Priscus, who refused to pay the price, how three of them were destroyed and then three more, and how finally the required price was paid for the remaining three, points to a belief that the material of the oracles had once been larger than that which came to Rome. There is also the assertion that the utterances of the Sibyl were at that time recorded in books. This fact suggests that oracular responses had long been known at Cumæ, and that some persons, of whose character and functions we know nothing, had from time to time written them down, so that a handbook of divination had come into existence.
[938]. In whatever manner the oracles were first brought to Rome it is certain that they were accepted by the Romans in all good faith, and they came to play a very important part in the conduct of public affairs. They were placed in the temple of Jupiter Capitolinus under the charge of two men (duumviri), and later a college was established for their guardianship. They were used in Rome especially for guidance in national calamities: when the existence of the city was threatened by the victorious career of Hannibal, it was the Sibyl who prescribed the importation of the worship of the Phrygian Great Mother. It is certain that the books were manipulated by political and religious leaders for their own purposes, old dicta being recast and new ones inserted as occasion required;[1725] but probably this procedure was unknown to the people—it does not appear that it affected their faith. Even Augustine speaks of the theurgi as dæmones, and cites a passage from the Erythræan Sibyl as a prediction of Christ.[1726]
[939]. To the poetical books which have come down to us under the name of Jewish Sibylline Oracles no value attaches for the history of the Sibyl except so far as they are an indication of the hold that the conception kept on men's minds.[1727] They are a product of the passion for apocalyptic writing that prevailed among the Jews and Christians in Palestine and Alexandria, from the second century B.C. into the third century of our era. The fame of the Græco-Roman Sibyl was widespread, and to the Jews and Christians of that time it seemed proper that she should be made to predict the history of Judaism and Christianity; possibly it was believed that such a prophetess must have spoken of this history. Naturally the Jewish Sibyl has a Biblical genealogy—she is the daughter of Noah.
[940]. Her utterances, given in heavy Greek hexameters, have been preserved for us in a great mass of ill-arranged fragments, with many repetitions, indicating them as the work of various authors. What we have is clearly only a part of what was produced, but the nature of the whole body of pseudo-predictions is easily understood from the material that has been preserved. They follow the history down to the author's time, giving it sometimes an enigmatical form, and the future is described in vague phrases that embody the guesses or hopes of the writer. It seems certain that all of the existent material of these oracles is from Jewish and Christian hands. Even when Greek mythical stories are introduced, as in the euhemeristic description of the origin of the Greek dynasties of gods in the third book, the whole is conceived under the forms of Jewish or Christian thought. The Sibyllines are quoted by Josephus and by many Christian writers from Justin Martyr to Augustine and Jerome and later. They give a picture of certain Jewish and Christian ideas of the period and of the opinions held concerning certain political events, but otherwise have no historical value. An illustration of the fact that the belief in them as real inspired prediction continued to a late time is found in the hymn Dies Irae, in which the Sibyl is cited along with David as a prophet of the last judgment. The whole history of the figure is a remarkable illustration of the power of a written record, held to be a divine revelation, to impress men's minds and control their beliefs and actions.
[941]. While divination has played a great part in the religious history of the world, it has rarely brought about important political or religious results.[1728] The exceptions are the great Greek oracles of Dodona and Delphi and the Roman Sibylline Books; to these last, as is observed above, the Roman people owed the introduction of some important religious cults. But for ordinary procedures priests and other officiators everywhere were disposed to give favorable responses, especially to the questions of prominent men; and military and other political enterprises were usually in such form that they could not conveniently be modified in accordance with unfavorable omens—the omen had to be favorable. There were exceptions, but this was the general rule. The science of divination, however, did good service in fostering the observation of natural phenomena, and especially in the development of astronomy and anatomy. In connection with these observations it called into being bodies of men—corporations that in process of time became centers of general culture.
[942]. On the ethical side it may be doubted whether divination has been an advantage to society. It has produced much deceit, unconscious and conscious. Whether diviners believed or did not believe in their science, the result was bad. If they did not believe, they fostered a system of deceit. Whether there was real belief or not, the practice of divination encouraged false methods and turned men's minds away from immediate appeals to the deity, and in general from a spiritual conception of religion. On the other hand, it helped to maintain the external apparatus of religion, which for ancient life was an important thing. Like all great institutions its effects have been partly good, partly bad. It belongs to a lower stage of human thought and tends to disappear gradually before enlightenment.
