Another testimony to the weakening of popular faith in the Hellenistic age is the decay of the institution of the Oracle. This, also, is of early date; as early as the fifth and fourth century we hear much less of the interference of the oracles in political matters than in earlier times. The most important of them all, the Delphic Oracle, was dealt a terrible blow in the Holy War (356-346 B.C.), when the Phocians seized it and used the treasures which had been accumulated in it during centuries to hire mercenaries and carry on war. Such proceedings would assuredly have been impossible a century earlier; no soldiers could have been hired with money acquired in such a way, or, if they could have been procured, all Hellas would have risen in arms against the robbers of the Temple, whereas in the Holy War most of the states were indifferent, and several even sided with the Phocians. In the succeeding years, after Philip of Macedonia had put an end to the Phocian scandal, the Oracle was in reality in his hands—it was during this period that Demosthenes stigmatised it as the mouthpiece of Philip. In the succeeding centuries, too, it was dependent on the various rulers of Hellas and undoubtedly lost all public authority. During this period we hear very little of the oracles of Hellas until the time before and after the birth of Christ provides us with definite evidence of their complete decay. Thus Strabo, who wrote during the reign of Augustus, says that the ancients attached more importance to divination generally and oracles more particularly, whereas people in his day were quite indifferent to these things. He gives as the reason that the Romans were content to use the Sibylline books and their own system of divination. His remark is made _a propos_ of the Oracle in Libya, which was formerly in great repute, but was almost extinct in his time. He is undoubtedly correct as to the fact, but the decline of the oracular system cannot be explained by the indifference of the Romans. Plutarch, in a monograph on the discontinuance of the oracles, furnishes us with more detailed information. From this it appears that not only the Oracle of Ammon but also the numerous oracles of Boeotia had ceased to exist, with one exception, while even for the Oracle at Delphi, which had formerly employed three priestesses, a single one amply sufficed. We also note the remark that the questions submitted to the Oracle were mostly unworthy or of no importance.
