*Religion.* Greek religion, like Greek literature, had attained a more advanced stage than that of Rome, and possessed a rich mythology when the Romans had barely begun to ascribe distinct personalities to their gods. Hence there came about a ready identification between Greek and Roman divinities to whom similar powers were ascribed and the wholesale adoption of Greek mythological lore. By the close of the third century B. C. there was formally recognized in Rome a group of twelve greater divinities who were identical with the twelve Olympic gods of Greece. There ensued also a rapid neglect of the minor Latin divinities whose place was taken by those of Greek origin. The old impersonal Roman deities had given place to anthropomorphic Hellenic conceptions. This is reflected in the acceptance of Greek types for the plastic representations of the gods, a strong demand for which arose with the acquaintance of the works of art carried off from Syracuse and other Greek cities. An important factor in this hellenization of the Roman religion was the influence of the Sibylline Books, a collection of Greek oracles imported from Cumae in the days of the Roman kings and consulted in times of national danger.
*The decree of the Senate against Bacchanalian societies: 186 B. C.* But Greek influence in the sphere of religion went deeper than the identification of Greek and Roman divinities, for the emotional cult of Bacchus with its mystic ceremonies and doctrines made its way into Italy where religious associations for its celebration were formed even in Rome itself. The demoralizing effects of this worship called forth a senatorial investigation which resulted, as we have seen, in the suppression of these associations. A similar action was taken with regard to the Chaldean astrologers, banished from Italy in 139 B. C.
*The worship of the Great Mother.* Of a different character was the cult of the Great Mother officially introduced into Rome in the year 204 B. C. This was in essence a native nature worship of Asia Minor, disguised with a veneer of Hellenism. It was the first of the so-called Oriental cults to obtain a footing in the Roman world.
*Skepticism and Stoicism.* Although the formalities of religion in so far as they concerned public life were still scrupulously observed, there was an ever increasing skepticism with regard to the existence and power of the gods of the Graeco-Roman mythology. This was especially true of the educated classes, who were influenced to a certain extent by the rationalism of Euhemerus, whose work on the origin of the gods had been translated by Ennius, but much more by the pantheism of the Stoic philosophy. The Stoic doctrines, with their practical ethical prescriptions, made a strong appeal to the Roman character and found an able expositor in Panaetius of Rhodes who taught under the patronage of Scipio Aemilianus.
