Friedrich Wilhelm Nietzsche 
Case Of Wagner, Nietzsche Contra Wagner, and Selected Aphorisms. 

Nietzsche wrote the rough draft of "The Case of Wagner" in Turin, during the month of May 1888; he completed it in Sils Maria towards the end of June of the same year, and it was published in the following autumn. "Nietzsche contra Wagner" was written about the middle of December 1888; but, although it was printed and corrected before the New Year, it was not published until long afterwards owing to Nietzsche’s complete breakdown in the first days of 1889
