We find traces of this phenomenon, which at first seems so inexplicable, among the other races of antiquity, but it is nowhere else so marked as it is in Egypt. When Egypt, after being for three centuries subject to the influence and supremacy of the Greek genius, had lost all but the shadow of its former independence and national life; when all the energy and intellectual activity which remained to it was concentrated at the Greco-Syrian rather than Egyptian Alexandria, the ancient religion of the race lost all its highest branches.[75] The aspirations towards monotheism took a form that was either philosophical and Platonic or Christian; and as for the cultivated spirits who wished to continue the personification of the eternal forces of the world and of the laws which govern them, these laws and forces presented themselves to their minds in the forms which had been figured and described by the sculptors, painters, and writers of Greece. They accepted, without hesitation or dispute, the numbers and physical characteristics of the divine types of Greece. From end to end of the habitable earth, as the Greeks boasted, the gods of the Hellenic pantheon absorbed and assimilated all those of other nationalities; within the boundaries of the Roman Empire, at least, its polytheism became a kind of universal religion for civilized humanity, and was adopted by nations of the most diverse origin and language. The lower classes alone, who read neither Homer nor Hesiod and were unable to admire the statues of the Greek sculptors, were kept free from the powerful and softening influence of poetry and art. They guarded with obstinacy the ancient foundations of their early faith, and in the void left by the disappearance of the national gods, their primitive beliefs seem to have put on a new life and to have enjoyed a restored _prestige_. Thus we may see, in forest clearings, the ancient but still vigorous stumps of great trees which have been felled send out fresh shoots to renew their youth.
