Now this early religion of which I have been giving a brief summary was the religion of a little city-state; it was suited to a small, unimaginative community. As such it remained formal and practical—a religion intended to secure material blessings; but it lacked all spiritual elements, and offered little or nothing to satisfy man’s natural hope for a happy future life. More than this, it contained little to ennoble daily life, save as it taught the lesson of duty and of fidelity towards the gods in the performance of contracts agreed upon. Yet it was not an uncomfortable religion for unreflective men, winning their existence from the soil and gaining their wealth from crops, their power through war. It did not, however, have in it the possibility of satisfying men’s higher desires. Under the influence of the Greeks and the Etruscans the Hellenic gods were early introduced to Rome. The temple of Jupiter on the Capitoline, which the Tarquin kings apparently built to establish a new religious center associated with their own dynasty, housed Jupiter, Juno, and Minerva; but they were only the Greek gods Zeus, Hera, and Athena, who had travelled to Rome by way of Etruria. In this temple the gods were represented in human form, and thereafter the process of anthropomorphizing and individualizing the divinities must have gone on apace. Some gods came by migration and trade, like the Greek Castor and Pollux, who were introduced to Rome from the neighboring town of Tusculum, and Hercules, whom Greek immigrants had established at Tibur. But the greatest influence in introducing Greek gods was the Sibylline Books. Whenever need pressed the state, these books were consulted that they might indicate what new means should be employed to win divine aid. We can name at least ten Greek divinities who were thus brought in before the outbreak of the Second Punic War. Apollo must have come at the time of the acquisition of the Sibylline Books, or soon after, for the Books were believed to contain his directions; we know that he had a temple by 433 B.C. Under the name of the Italian divinity Mercury, the Greek Hermes had received a shrine in 495; two years later the triad Ceres, Liber, and Libera, an Italian disguise for Demeter, Dionysus, and Kore, were domiciled near Mercury; and not long before 399 B.C. the Greek Poseidon, with the name of Neptunus, was established near the city walls. Then there was apparently a pause for about a century. But in 293 B.C. a serious plague ravaged the city, so that the Sibylline Books were consulted. This time they were found to say that relief was certain if the Greek god of healing, Aesculapius, were brought to Rome. The divinity consented, and two years later a temple was dedicated to him on the island in the Tiber where the hospital of San Bartolomeo today continues his kindly work. Again in the crisis of the year 249 B.C., warned by many omens, the Romans obeyed the Books’ injunction to establish on the
