There are men who, from a lack of experience or out of apathy, turn mockingly away from such phenomena as from a “sickness of the people,” with a sense of their own health and filled with pity. These poor people naturally do not have any sense of how deathly and ghost-like this very “Health” of theirs sounds, when the glowing life of the Dionysian throng roars past them. Under the magic of the Dionysian, not only does the bond between man and man lock itself in place once more, but also nature itself, now matter how alienated, hostile, or subjugated, rejoices again in her festival of reconciliation with her prodigal son, man. The earth freely offers up her gifts, and the beasts of prey from the rocks and the desert approach in peace. The wagon of Dionysus is covered with flowers and wreaths. Under his yolk stride panthers and tigers.
On the other hand, we do not need to speak merely hypothetically when we have to expose the immense gap which separates the Dionysian Greeks from the Dionysian barbarians. In all quarters of the old world (setting aside here the newer worlds), from Rome to Babylon, we can confirm the existence of Dionysian celebrations, of a type, at best, related to the Greeks in much the same way as the bearded satyr whose name and characteristics are taken from the goat is related to Dionysus himself. Almost everywhere, the central point of these celebrations consisted of an exuberant sexual promiscuity, whose waves flooded over all established family practices and traditional laws. The wildest bestiality of nature was here unleashed, creating an abominable mixture of lust and cruelty, which has always seemed to me the real witches' potion.
The language of song and poetry of such a doubly defined celebrant was for the Homeric Greek world something new and unheard of. Dionysian music especially awoke in that world fear and terror. If music was apparently already known as an Apollonian art, this music, strictly speaking, was a rhythmic pattern like the sound of waves, whose artistic power had developed for presenting Apollonian states of mind. The music of Apollo was Doric architecture expressed in sound, but only in intimate tones, characteristic of the cithara [a traditional stringed instrument}. The un-Apollonian character of Dionysian music keeps such an element of gentle caution at a distance, and with that turns music generally into emotionally disturbing tonal power, a unified stream of melody, and the totally incomparable world of harmony.
To grasp this total unleashing of all symbolic powers, man must already have attained that high level of freedom from the self which seeks to express itself symbolically in those forces. Because of this, the dithyrambic servant of Dionysus will understand only someone like himself. With what astonishment must the Apollonian Greek have gazed at him! With an amazement which was all the greater as he sensed with horror that all this may not be really foreign to him, that even his Apollonian consciousness was covering the Dionysian world in front of him, like a veil.
