The pandemonium in which Dionysus, himself, and his divine entourage make their entry — that pandemonium which the human horde, struck by his spirit, unleashes — is a genuine symbol of religious ecstasy.
Otto grounds pandemonium in classical religion as the authentic epiphanic atmosphere of Dionysus, distinguishing it as a sacred phenomenon inseparable from its polar opposite, deathly silence.
