We note in passing that the allegorical interpretation of mythology, said to have been first introduced as early as the sixth century before Christ by Theagenes of Rhegium, was well established in the age of Plato, and here, as in the Phaedrus (229-30), though for a different reason, was rejected by him. That anachronisms whether of religion or law, when men have reached another stage of civilization, should be got rid of by fictions is in accordance with universal experience. Great is the art of interpretation; and by a natural process, which when once discovered was always going on, what could not be altered was explained away. And so without any palpable inconsistency there existed side by side two forms of religion, the tradition inherited or invented by the poets and the customary worship of the temple; on the other hand, there was the religion of the philosopher, who was dwelling in the heaven of ideas, but did not therefore refuse to offer a cock to Æsculapius, or to be seen saying his prayers at the rising of the sun. At length the antagonism between the popular and philosophical religion, never so great among the Greeks as in our own age, disappeared, and was only felt like the difference between the religion of the educated and uneducated among ourselves. The Zeus of Homer and Hesiod easily passed into the 'royal mind' of Plato (Philebus, 28); the giant Heracles became the knight-errant and benefactor of mankind. These and still more wonderful transformations were readily effected by the ingenuity of Stoics and neo-Platonists in the two or three centuries before and after Christ. The Greek and Roman religions were gradually permeated by the spirit of philosophy; having lost their {xxxix} ancient meaning, they were resolved into poetry and morality; and probably were never purer than at the time of their decay, when their influence over the world was waning.
