Aelian mentions other remarkable examples of the piety displayed by brutes. ‘Elephants worship the sun, stretching out their trunks to it like hands when it rises while men doubt the existence of the gods, or at least their care for us.’ ‘There is an island in the Black Sea, sacred to Heracles, where the mice touch nothing that belongs to the god. When the grapes which are intended to be used for his sacrifices begin to ripen, they quit the island in order to escape the temptation of nibbling at them, coming back when the vintage is over. Hippo, Diagoras, Herostratus, and other enemies of the gods would, no doubt, spare these grapes just as little as anything else that was consecrated to their use.’[353] It is, perhaps, characteristic of the times that Aelian’s stories should redound more especially to the credit of Asclêpius and Heracles, who were not gods of the first order, but demi-gods or deified mortals. Their worship, like that of the Nature-powers connected with earth rather than with heaven, belongs particularly to the popular religion, and seems to have been repressed or restrained in societies organised on aristocratic principles. And as more immediate products of the forces by which supernaturalist beliefs are created and maintained, such divinities would profit by the free scope now given to popular predilections. In their case also, as with the earth-goddesses Dêmêtêr and Isis, a more immediate and affectionate relation might be established between the believer and the object of his worship than had been possible in reference to the chief Olympian gods. Heracles had lived the life of a man, his activity had been almost uniformly beneficent, and so he was universally invoked, as a helper and healer, in the sick-chamber no less than on the storm-tost ship.[354] Asclêpius was still more obviously the natural refuge of those who were afflicted with any bodily disease, and, in a time of profound peace, this was of all calamities the most likely to turn men’s thoughts towards a supernatural protector. Hence we find that where, apart from Christianity, the religious enthusiasm of the second century reaches its intensest expression, which is in the writings of the celebrated rhetor Aristeides, Asclêpius comes in for the largest share of devotional feeling. During an illness which continued through thirteen years, Aristeides sought day and night for help and inspiration from the god. It came at last in the usual form of a prescription communicated through a dream. Both on this and on other occasions, the excitement of an overwrought imagination combined with an exorbitant vanity made the sophist believe himself to be preferred above all other men as an object of the divine favour. At one time he would see himself admitted in his dreams to an exchange of compliments with Asclêpius; at other times he would convert the most ordinary incidents into signs of supernatural protection. Thus his foster-sister having died on the
