With reference to Archilochus, it has been established by critical research that he introduced the _folk-song_ into literature, and, on account thereof, deserved, according to the general estimate of the Greeks, his unique position alongside of Homer. But what is this popular folk-song in contrast to the wholly Apollonian epos? What else but the _perpetuum vestigium_ of a union of the Apollonian and the Dionysian? Its enormous diffusion among all peoples, still further enhanced by ever new births, testifies to the power of this artistic double impulse of nature: which leaves its vestiges in the popular song in like manner as the orgiastic movements of a people perpetuate themselves in its music. Indeed, one might also furnish historical proofs, that every period which is highly productive in popular songs has been most violently stirred by Dionysian currents, which we must always regard as the substratum and prerequisite of the popular song. First of all, however, we regard the popular song as the musical mirror of the world, as the Original melody, which now seeks for itself a parallel dream-phenomenon and expresses it in poetry. _Melody is therefore primary and universal,_ and as such may admit of several objectivations, in several texts. Likewise, in the naïve estimation of the people, it is regarded as by far the more important and necessary. Melody generates the poem out of itself by an ever-recurring process. _The strophic form of the popular song_ points to the same phenomenon, which I always beheld with astonishment, till at last I found this explanation. Any one who in accordance with this theory examines a collection of popular songs, such as "Des Knaben Wunderhorn," will find innumerable instances of the perpetually productive melody scattering picture sparks all around: which in their variegation, their abrupt change, their mad precipitance, manifest a power quite unknown to the epic appearance and its steady flow. From the point of view of the epos, this unequal and irregular pictorial world of lyric poetry must be simply condemned: and the solemn epic rhapsodists of the Apollonian festivals in the age of Terpander have certainly done so.
