Nietzsche
at length           that the friend of his fancy and the real Richard
Wagner--the composer of Parsifal--were not one; the fact dawned
upon him slowly; disappointment upon disappointment, revelation after
revelation, ultimately brought it home to him, and though his best
instincts were naturally opposed to it at first, the revulsion of
feeling at last became too strong to be ignored, and Nietzsche was
plunged into the blackest despair.
