Virgil, indeed, alone of Roman writers, made any contribution of real importance to the development of the Vision legend in literature, though that contribution is the flower and consummation of the legend as it appears in the purely classical tradition. For Virgil, saturated with the Hellenic culture, while remaining intensely Roman in his political views and national sentiment, remains free from any tincture of Oriental ideas. Earlier than Plutarch by more than a century, his treatment of the subject is more modern in style and spirit, although, in his pictures of the other world, he repeats and combines the ideas which the ancients had held concerning it. His topography of the other world and of the approaches thereto agrees so closely with the humorous account in the _Frogs_ of Aristophanes, which, evidently, he has no intention of copying, as to make it clear that both poets followed, in the main, a generally accepted tradition. So, too, in his descriptions of the Elysian Fields and of Tartarus, Virgil simply reproduces in substance the many similar descriptions which occur in the Greek poets and philosophers; and although he perfects these with many exquisite touches of his own, such original contributions of his belong rather to the domain of art than of eschatology. To take one instance, his enumeration of those righteous ones who are admitted to the seats of the blest, including, as it does, Inventas aut qui vitam excoluere per artes, Quique sui memores alios fecere merendo (_Æn._ vi. 663-4), could only have been written in an age of self-conscious culture.
