day of his own recovery from a dangerous epidemic, it was revealed to him in a dream that her life had been accepted as a ransom for his. We are told that the monks of the Middle Ages could not refrain from expressing their indignant contempt for the insane credulity of Aristeides, in marginal notes on his orations; but the last-mentioned incident, at least, is closely paralleled by the well-known story that a devout lady was once permitted to redeem the life of Pius IX. by the sacrifice of her own.[355] Besides this increasing reverence paid to the deified mortals of ancient mythology, the custom of bestowing divine honours on illustrious men after or even before their death, found new scope for its exercise under the empire. Among the manifestations of this tendency, the apotheosis of the emperors themselves, of course, ranks first. We are accustomed to think of it as part of the machinery of despotism, surrounded by official ceremonies and enforced by cruel punishments; but, in fact, it first originated in a spontaneous movement of popular feeling; and in the case of Marcus Aurelius at least, it was maintained for a whole century, if not longer, by the mere force of public opinion. And many prophecies (which, as usual, came true) were made on the strength of revelations received from him in dreams.[356] But a much stronger proof of the prevalent tendency is furnished by the apotheosis of Antinous. In its origin this may be attributed to the caprice of a voluptuous despot; but its perpetuation long after the motives of flattery or of fear had ceased to act, shows that the worship of a beautiful youth, who was believed to have given his life for another, satisfied a deep-seated craving of the age. It is possible that, in this and other instances, the deified mortal may have passed for the representative or incarnation of some god who was already believed to have led an earthly existence, and might therefore readily revisit the scene of his former activity. Thus Antinous constantly appears with the attributes of Dionysus; and Apollonius of Tyana, the celebrated Pythagorean prophet of the first century, was worshipped at Ephesus in the time of Lactantius under the name of Heracles Alexicacus, that is, Heracles the defender from evil.[357] VII.
