The story of the sale of the Sibylline Books to King Tarquin is familiar to all: how the Cumaean Sibyl brought to the King nine books of oracles; when he refused their purchase she went away and burned three, and offered the remaining six at the price she had originally demanded for the nine; upon his second refusal she burned three more, and then offered the last three on the original terms. Tradition says that her confidence in human curiosity was justified, and that Tarquin, after consultation with his seers, purchased the last three books.[262] Although we cannot today determine what historical truth lies behind this naïve story, the date of the reputed sale—the sixth century before our era—coincides with the first period of Greek influence at Rome. By their geographical position the early Romans were exposed to influences from two superior civilizations—the Etruscan at the north, the Greek in southern Italy. The Etruscans had entered Italy probably from the East at some time between the eleventh and the eighth centuries B.C.; but before their coming they had advanced in culture beyond the Latins whose territories they touched on the Tiber. By the sixth century certainly the Romans had come into close political and commercial relations with them, and indeed had already felt their power, for an Etruscan dynasty ruled at Rome. In spite of the patriotic efforts of Roman historians, we can now see that the Etruscan domination lasted long after the traditional expulsion of the kings. From their northern neighbors the Romans took many political and social institutions as well as certain religious elements. The most important of the latter were the College of the Haruspices, the Great Games in the Circus, the Triumph, and the Capitoline Triad of Jupiter, Juno, and Minerva, which was established by the Tarquins to strengthen their political position. But far greater was the influence of the Greeks, whose colonies, firmly established, rich and prosperous, fringed the whole southern part of the Italian peninsula. From them the Romans got their alphabet, their weights and measures, and certain political institutions; but most important of all for our present interest, they received from them religious influences which finally so overlaid the early Roman religion that the Romans themselves could not well discover its original elements, and we are hardly in a better situation. Furthermore, if we can believe that there is a kernel of historic truth in the story that King Tarquin the Proud sent an embassy to consult the oracle at Delphi, Rome was not wholly without connection with Greece proper in the sixth century before our era. We have then in Rome of the sixth and earlier centuries an example of a state whose rude civilization was brought into close and intensive contact with the higher civilizations about her. It was inevitable that the results should be rapid and profound.
