The book chronicles the fictitious travels and speeches of Zarathustra. Zarathustra's namesake was the founder of Zoroastrianism, usually known in English as Zoroaster. Nietzsche is clearly portraying a "new" or "different" Zarathustra, one who turns traditional morality on its head. Zarathustra has a simple characterisation and plot, narrated sporadically throughout the text. It possesses a unique experimental style, one that is, for instance, evident in newly invented "dithyrambs" narrated or sung by Zarathustra. Likewise, the separate Dithyrambs of Dionysus was written in autumn 1888, and printed with the full volume in 1892, as the corollaries of Zarathustra's "abundance". Some speculate that Nietzsche intended to write about final acts of creation and destruction brought about by Zarathustra. However, the book lacks a finale to match that description; its actual ending focuses more on Zarathustra recognizing that his legacy is beginning to perpetuate, and consequently choosing to leave the higher men to their own devices in carrying his legacy forth. Zarathustra also contains the famous dictum "God is dead", which had appeared earlier in The Gay Science. In his autobiographical work Ecce Homo, Nietzsche states that the book's underlying concept is discussed within "the penultimate section of the fourth book" of 'The Gay Science' (Ecce Homo, Kaufmann). It is the eternal recurrence of the same events.
