The numerous fables mixed with the Grecian creed, sufficiently venerable, as we have seen, not to be disdained, but not so sacred as to be forbidden, were another advantage to the poet. For the traditions of a nation are its poetry! And if we moderns, in the German forest, or the Scottish highlands, or the green English fields, yet find inspiration in the notions of fiend, and sprite, and fairy, not acknowledged by our religion, not appended as an apocryphal adjunct to our belief, how much more were those fables adapted to poetry, which borrowed not indeed an absolute faith, but a certain shadow, a certain reverence and mystery, from religion! Hence we find that the greatest works of imagination which the Greeks have left us, whether of Homer, of Aeschylus, or of Sophocles, are deeply indebted to their mythological legends. The Grecian poetry, like the Grecian religion, was at once half human, half divine--majestic, vast, august --household, homely, and familiar. If we might borrow an illustration from the philosophy of Democritus, its earthlier dreams and divinations were indeed the impressions of mighty and spectral images inhabiting the air. [62] XXIV. Of the religion of Greece, of its rites and ceremonies, and of its influence upon the moral and intellectual faculties--this-- already, I fear, somewhat too prolixly told--is all that at present I deem it necessary to say. [63] We have now to consider the origin of slavery in Greece, an inquiry almost equally important to our accurate knowledge of her polity and manners.
