And as regards the critical point urged by Palaiphatos, Strabo, and Polybius, that pure invention on Homer’s part is inconceivable, we may without scruple allow it, for myths, like constitutions, grow gradually, and are not formed in a day. But between a poet’s deliberate creation and historical accuracy there is a wide field of the mythopœic faculty. This Euhemeristic theory was welcomed as an essentially philosophical and critical method by the unscientific Romans, to whom it was introduced by the poet Ennius, that pioneer of cosmopolitan Hellenicism, and it continued to characterise the tone of ancient thought on the question of the treatment of mythology till the rise of Christianity, when it was turned by such writers as Augustine and Minucius Felix into a formidable weapon of attack on Paganism. It was then abandoned by all those who still bent the knee to Athena or to Zeus, and a general return, aided by the philosophic mystics of Alexandria, to the allegorising principle of interpretation took place, as the only means of saving the deities of Olympus from the Titan assaults of the new Galilean God. In what vain defence, the statue of Mary set in the heart of the Pantheon can best tell us. Religions, however, may be absorbed, but they never are disproved, and the stories of the Greek mythology, spiritualised by the purifying influence of Christianity, reappear in many of the southern parts of Europe in our own day. The old fable that the Greek gods took service with the new religion under assumed names has more truth in it than the many care to discover. Having now traced the progress of historical criticism in the special treatment of myth and legend, I shall proceed to investigate the form in which the same spirit manifested itself as regards what one may term secular history and secular historians. The field traversed will be found to be in some respects the same, but the mental attitude, the spirit, the motive of investigation are all changed. There were heroes before the son of Atreus and historians before Herodotus, yet the latter is rightly hailed as the father of history, for in him we discover not merely the empirical connection of cause and effect, but that constant reference to Laws, which is the characteristic of the historian proper.
