Thus Spake Zarathustra

Thus Spake Zarathustra is a philosophical novel by German philosopher Friedrich Nietzsche, composed in four parts. Described by Nietzsche himself as "the deepest ever written," the book is a dense and esoteric treatise on philosophy and morality, featuring as protagonist a fictionalized prophet descending from his mountain retreat to mankind, Zarathustra. 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. 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.
