Thus Spake Zarathustra is a philosophical novel by German philosopher Friedrich Nietzsche. The book chronicles the fictitious travels and speeches of Zarathustra. Zarathustra's namesake was the Persian 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. He goes on to characterize what the name of Zarathustra means in my mouth, the mouth of the first immoralist: The book embodies a number of innovative poetical and rhetorical methods of expression. It serves as a parallel and supplement to the various philosophical ideas present in Nietzsche's body of work. He has, however, said that "among my writings my Zarathustra stands to my mind by itself." Emphasizing its centrality and its status as his magnum opus.
