With so powerful a protector, Alexander might safely bid his enemies defiance. The governor of Bithynia had to entreat Lucian, whose life had been threatened by the impostor, to keep out of harm’s way. ‘Should anything happen to you,’ he said, ‘I could not afford to offend Rutilianus by bringing his father-in-law to justice.’ Even the best and wisest man then living yielded to the prevalent delusion. Marcus Aurelius, who was at that time fighting with the Marcomanni, was induced to act on an oracle from Abonuteichus, promising that if two lions were thrown into the Danube a great victory would be the result. The animals made their way safely to the opposite bank; but were beaten to death with clubs by the barbarians, who mistook them for some outlandish kind of wolf or dog; and the imperial army was shortly afterwards defeated with a loss of 20,000 men.[346] Alexander helped himself out of the difficulty with the stale excuse that he had only foretold a victory, without saying which side should win. He was not more successful in determining the duration of his own life, which came to an end before he had completed seventy years, instead of lasting, as he had prophesied, for a hundred and fifty. This miscalculation, however, seems not to have impaired his reputation, for even after his death it was believed that a statue of him in the market-place of Parium in Mysia had the power of giving oracles.[347] VI. Another wide-spread superstition was the belief in prophetic or premonitory dreams. This was shared by some even among those who rejected supernatural religion,—a phenomenon not unparalleled at the present day. Thus the elder Pliny tells us how a soldier of the Praetorian Guard in Rome was cured of hydrophobia by a remedy revealed in a dream to his mother in Spain, and communicated by her to him. The letter describing it was written without any knowledge of his mishap, and arrived just in time to save his life.[348] And Pliny was himself induced by a dream to undertake the history of the Roman campaigns in Germany.[349] Religious believers naturally put at least equal confidence in what they imagined to be revelations of the divine will. Galen, the great physician, often allowed himself to be guided by dreams in the treatment of his patients, and had every reason to congratulate himself on the result. The younger Pliny, Suetonius, Dion Cassius, and the emperors Augustus and Marcus Aurelius, were all influenced in a similar manner; and among these Dion, who stands last in point of time, shows by his repeated allusions to the subject that superstition, so far from diminishing, was continually on the increase.[350]
